Title: Remote sensing for practical forestry: Arboriculture to UAVs
In remote sensing, forests are often put into context by reference to REDD
(Reducing emissions from deforestation and forest degradation) and loose
associations with 'ecosystem services'. However, more than just a tracking
and monitoring tool for carbon-credit forests, remote sensing offers
opportunities for practical forest management. Responsive forest management
in the UK takes particular relevance at the present time due to recent
arrivals of foreign pests and pathogens as well as rising incidence of
climatic anomaly-related tree stress responses. I will discuss the use of
and research into remote sensing tools to tackle issues unique to forests,
from the platforms, to the instruments, to the analysis.

Dr. Karin Viergever
Head of Land Use and Spatial Analysis, Ecometrica, Edinburgh
Title: Our Ecosystem: the development of a web-platform that brings spatial data to non-GIS experts
Ecometrica is an Edinburgh-based provider of consultancy and web-based services in greenhouse gas accounting, land use and ecosystem assessment. Our programming team and analysts have developed Our Ecosystem (OE), a web-based data viewing and sharing platform that is designed to make spatial data accessible to people that do not have GIS or remote sensing expertise. Our aim was to produce a platform that would make it easy for non-GIS specialists to access, organise, share, query and analyse spatial data on land cover and ecosystem services.
The presentation will discuss the reasons behind the development of the platform and the technical challenges faced in both the backend (e.g. the OE ‘machine’) and frontend (e.g. communicating complex data to non-expert users and getting the user interface right).
Current examples of OE applications include mapping and quantification of resources and impacts on resources; showing or checking compliance to environmental legislation; monitoring changes to vegetation and other resources; and publication of scientific research. Researchers and other organisations that have produced data layers that they would like to share with others are encouraged to use the Our Ecosystem platform as a means to publish their data. During the presentation several examples of OE applications in the application fields of forest and environmental management will be shown.

Title: Smart Cities: Big Data, Real Time Transport, Social Media and Urban Simulation
I will explain how computers are being fast embedded into many different aspects of the built environment of cities and thus delivering many news kinds of data that pertain to change and movement, particularly in terms of transport flows and social networking. These data are large in the sense that every time an event occurs, the event is recorded and there may be as many as 10000 events per second, yielding data streams measured in millions of events. Making sense of all this is a major challenge and visualization as well as quite elaborate data mining is the key, but the smart city that is an obvious consequence of this digital revolution depends on how we use these new data streams, how we understand urban problems better and fashion more effective urban plans. We will illustrate these ideas from our work in London with the Oyster card system on London’s public transport, various social explorations into social media, digital participation and the development of longer term more traditional land use transport models that can be run now in almost real time. In short, the temporal events associated with spatial events in cities is changing the basis of how we think about their planning. The focus is shifting from long to short term planning as indeed is our own attention span in an era when life seems ever faster. We illustrate these ideas with notions about how we can account for disruptions in cities, unexpected events and how big data is providing us with possibilities for understanding and indeed control of cities that we have never been realized before.

Title: Natural Flood Management within the Flood Risk Management (Scotland) Act
The hydrological impact of diffuse land use changes often associated with NFM push the capabilities of even the most sophisticated hydrological techniques. With an inevitable high degree of uncertainty in mind, a series of GIS based screening tools will be presented that will assist the practitioner to screen for areas where NFM techniques may be effective, prior to more detailed and focused assessment. These screening methods have been designed to be rapid, informative and can be implemented with existing national datasets.
An overview of a novel method to quantify the hydrological impacts of fluvial NFM measures using a GIS based spatially distributed, semi-physical hydrological model will also be presented. Although at present still largely speculative, this method may provide a means of testing NFM measures against more traditional flood risk management strategies by retaining a link to current UK hydrological practice. While this method will provide hard figures it will be important to remember the high degree of uncertainty necessarily associated with such quantitative approaches.

Title: Humanising Archaeological GIS
GIS applications have become increasingly popular within archaeology although not without an element of controversy. This talk will outline the early applications and critiques and then focus on attempts to overcome the perceived positivist stance of GIS technology and its possible integration within post-modernist theoretical approaches to the past. The emphasis is on movement and visibility and how the two can be modelled and combined. A series of case-studies will be presented which attempt to model an embodied engagement with the material world.

Title: Transport schematics: usability, aesthetics, and evaluation
As urban rail networks around the world grow and develop, so the challenge to create attractive usable maps increases. Generally, designers begin with rules first used for the Berlin S-Bahn in 1931, and by Henry Beck for the London Underground in 1933, also known as octolinearity (horizontal and vertical lines and 45 degree diagonals). From the perspective of cognitive psychology, what are the requirements for a well-designed map versus a poorly designed one? Why might octolinearity assist usability? Is this really the optimum means of achieving the best possible design? Can objectives be better achieved if this constraint is relaxed? It is concluded that different networks have different underlying properties, and that these suit different rules.

Title: Geographically Weighted Regression: Modelling Spatial Heterogeneity
Geographically Weighted Regression is a technique for exploratory spatial data analysis. In "normal" regression with data for spatial objects we assume that the relationship we are modelling is uniform across the study area - that is, the estimated regression parameters are "whole-map" statistics. In many situations this is not necessarily the case, as mapping the residuals (the differences between the observed and predicted data) may reveal. Many different solutions have been proposed for dealing with spatial variation in these relationships. GWR provides means of modelling such relationships.
This seminar outlines the characteristics of spatial data and the challenges its use poses for analysis, the ideas underpinning geographically weighted regression and details the process of estimating and interpreting the outputs from GWR models. We finish with a brief survey of current issues in GWR and potential future developments.

Title: The Role of EO Consultants and SMEs within GMES
Environmental information is of crucial importance to understand how our planet and its climate are changing, the role played by human activities in these changes and how these will influence our daily lives.
The European Global Monitoring for Environment and Security (GMES) program aims to provide, or support the provision of, this information through a range of operational Earth Observation-based products and services. The products and services will address a number of key themes; marine, land, atmosphere, emergency, security and climate change. GMES also covers the space component, with the provision of data from the soon to be launched Sentinel series of satellites, and the in-situ component, by the coordination of Member State activities. Policymakers and public authorities at the EU level, the major users of GMES core products and services, will use the information to prepare, implement and monitor environmental legislation and policies across Europe. However, the GMES core products will also be the foundations for downstream services which will operate at the sub-EU level addressing Member State, Regions and local authorities.
The core services offer sustainable pan European input data which will promote the development of downstream services which offer a major opportunity for small to medium sized enterprises (SMEs) in the EO sector to expand their activities within a realistic local context. The current FP7 project GMES for Regions: Awareness and Access Link (GRAAL) will build a platform to help users better specify their demands for EO-based services and for SMEs to better market and promote the services they are offering. The next few years will therefore be a very important and exciting time in the European EO industry and this presentation will describe how the GMES Land theme has developed and some of the opportunities that lie ahead for SMEs.
Dr. Geoff Smith, Specto Natura Ltd., is an Earth Observation(EO) consultant with over 20 years experience in academia, government and industry. He has a PhD in imaging spectroscopy of vegetation from the University of Wales, Swansea and postgraduate qualifications in geophysics and EO. He has worked extensively with UK government delivering products and advice as well as representing UK interests at the European Level. He worked within a UK government agency undertaking a range of activities from blue-skies research to operational applications and has been responsible for successful bids to the UK government, the European Commission and the European Environment Agency. He has been involved in GMES from its early days working on the FP5 BIOPRESS, FP6 Geoland, FP6 BOSS4GMES projects and is now involved in other land related FP7 projects (Geoland 2, HELM, MS-MONINA & GRAAL). His focus is on land cover mapping activities with a user perspective and has provided technical input and management to UK national land cover map and CLC production projects. Previously, he was the head of the Section for EO at the Centre for Ecology and Hydrology, UK.

Title: Assessing the Accuracy of Crowdsourced Data
The use of informal, crowd-sourced geospatial data collected by non-professional volunteers (volunteered geographic information, VGI), is often regarded as a panacea for projects which are confronted by inadequate or unattainable official information. This seminar will examine how 'good' such informal data is, by assessing its quality using a number of different measures. Any integration of VGI and formal datasets, which is already happening in several applications, must take account of relative accuracies, completeness, currency and meaning. The results of tests on some of these metrics will be described.

Title: GIS Explorations in the Coastal Zone
Spatial data covering the coastal environment is increasingly
available at a range of scales and resolutions. Whilst there is great
potential for these spatial data to explore characteristics of the
coastal zone, particularly in terms of contemporary features, there
are also a number of limitations that can frequently constrain our
research process. This is particularly true when reconstructing past
environments and histories. Drawing on a range of projects
investigating coastal behaviour and environmental histories, this talk
will review coastal spatial data and reflect on the opportunities for
GIS and remote sensing in coastal studies.

Professor Richard Healey
School of Geography, University of Portsmouth
Title: New Developments in Historical GIS
The formative period of work in historical GIS from the late 1990's
onwards was characterised by the digitisation of published historical
census datasets and attention to the problems of administrative boundary
changes, using a variety of standard GIS and database tools. More
recently, the growing availability of very large individual level files
for 19th century censuses in the USA, the UK and parts of Northern
Europe, has created both major data processing challenges and immense
opportunities to broaden and deepen the scope of research in
demographically-related historical GIS. However, such fine-grained
datasets still have a very coarse temporal resolution by decade, and are
therefore limited for the analysis of shorter duration socio-economic
processes. Taking as a theme the mobility of 19th US industrial
workers, this presentation will examine new technical developments and
substantive issues that affect the deployment of historical GIS in these
data-rich environments, including the use of business intelligence
methodologies (data warehousing and OLAP), web-based visualisation
techniques and the perennial problems of data quality.

Title: Urban and Regional Models: Achievements and Challenges
Modelling the functioning and evolution of urban and regional systems has been, and is, one of the grand challenges of Twentieth and Twenty-First Century science. There is half a century or more of achievement which is reviewed briefly. The challenges for the future range from taking advantage of the wealth of new data and the demands this makes for effective warehousing through the optimum deployment of the models that work well – such as interaction models – to the challenge of modelling system dynamics and evolution. The concepts of abrupt change and of path dependence are developed and the idea of ‘urban DNA’ introduced. These models are illustrated with a range of applications from retail structures (and agent-based variants of conventional models) to some historical examples, including the evolution of the USA urban system in the Nineteenth Century.

Title: Commuter pollution exposure: can modal choice affect your health?
Most research suggests, that contrary to lay expectations, pollution exposure is higher among car occupants than and other road users. However recently a couple of studies has suggested otherwise. Most of these types of studies have occurred in areas of high traffic density. This presentation will give the results of a recently conducted study in Christchurch and Auckland, New Zealand, that assessed the relative exposure people travelling by car, bike, bus and train. It simultaneously monitored for particles of varying size fraction and carbon monoxide. It also used GPS and GIS technologies to track individuals to relate mobility to exposure.

Title: The Role of Urban Sensing in Managing Megacities
Many megacities are growing at an annual rate of over 6% and some will double their populations in the next decade. This incredibly rapid growth of megacities causes severe social, economical and ecological problems. New tools, techniques and policies are required to baseline and integrate the social, economic and environmental factors associated with megacities, to monitor growth and change across the megacity and to forecast areas of risk – all within shorter timeframes than previously accepted.
This presentation explores the role of ‘urban sensing’ that uses cellular phones, sensor technologies, GIS related technologies, Web 2.0 and crowdsourcing (mass collaboration using Web 2.0) to support the creation of a public infrastructure, a ‘data commons,’ that will allow the citizen to increasingly participate in politics, civics (including land administration and management), aesthetics and science. These emerging techniques have the potential to strengthen the Spatial Data Infrastructures and urban change information available to megacities.

Title: Using Open Standards for Delivery of Geo Related Data - Lessons and Thoughts
James Reid is one of the leading exponents of the use OpenGIS standards for the delivery of large-scale GI services in the UK. He leads a team which has built a spatial data infrastructure for the UK academic community. This presentation will report the findings from the Data Integration and Dissemination (DIaD) project, which is investigating the potential of using international open standards based techniques (Open Geospatial Consortia) to perform data linkage between two of the most heavily used UK academic census programme outputs - the aggregate statistical data and the output geographies. The primary objective of this work is to develop a data dissemination model which demonstrates a more generic capability - that of 'geo-linking'. Additionally, using the same standards based approach, the project will aim to demonstrate how further value added processing can be invoked by transforming the geo-linked outputs through a series of ancillary web processing services.
The presentation will review project progress, discuss issues arising from the work to date and suggest how open standards and open source software approaches to building spatial data infrastructure may (or may not) be prudent.

Title: Dynamic oscillations of the Last British Ice Sheet: new evidence from onshore and offshore
Recent work has presented an overview of the glacial landscape preserved on the northern UK continental shelf based on an extensive echosounder dataset [Bradwell et al., 2008a]. In this talk I will describe how this data was collected and how it has led to several new discoveries relating to the glaciation of the British Isles. The talk will highlight key lines of evidence within the offshore geomorphic record, augmented by new multibeam data, alongside cosmogenic nuclide analyses which spatially and temporally constrain the decay of the northern sector of the last British Ice Sheet. By focusing on the NW sector, I will highlight the detailed pattern of moraines preserved on the seabed and onshore - the morphology and distribution of which testify to the highly dynamic behaviour of a grounded palaeo-ice-sheet margin. Finally, I will consider several of these ice sheet oscillations, including the Wester Ross Readvance, within a wider context; and aim to convince you that ice caps in Scotland probably existed throughout the Lateglacial Interstadial.

Title: Understanding the Modifiable Areal Unit Problem
Most social science and some environmental data are available for areal units such as counties, districts, wards, postcode sectors, grid squares or pixels. A country or a study area can be divided up in many different ways and often the system of zones used for collection, modelling and display of data may be arbitrary or ‘modifiable’. However if the data are analysed, the results of the analysis may vary, sometimes very dramatically. This is the modifiable areal unit problem (MAUP). It was first discovered in the 1930s, and studied in detail by Openshaw (1984). It has two aspects: the scale problem, which concerns differences in statistical results for zonal systems at different scales (generally – but not always - larger units are linked to stronger correlations); and the zonation (or aggregation) problem, which concerns differences in results between zonal systems at the same scale but with different configurations of zones.
This paper is concerned with investigating how often and in what circumstances the MAUP is a problem, using zone design software to aggregate the smallest areal units in different ways, paying attention to consideration of equality in size, compactness of shape and social homogeneity. Results from the real zoning system can be compared with results from simulated systems, and the relationship of the MAUP to spatial autocorrelation and the impact of geographical processes.

Title: MapAction in Action
Ever wondered how geographical information systems (GIS) are being harnessed for humanitarian purposes?
MapAction is an established UK-registered charity, largely manned by unpaid volunteers, whose purpose is to deploy a trained team of specialist personnel to apply the power of GIS to map humanitarian relief operations. MapAction has experts in remote sensing imagery, communications, logistics, security, computing and medical skills in addition, of course, to GIS and GPS navigation skills. We're a team that works
efficiently and effectively under field conditions in fraught situations.
In such crisis', relief agencies need rapid answers to questions about 'where'. Where are the greatest needs? Where are the gaps that need to be filled? Aid that ends up in the wrong place is of no use in relieving human suffering. MapAction's work in disaster zones multiplies the efficiency of emergency response. We do this by setting up a field-mapping centre at the site of a disaster highlighting the places where relief help is most urgently needed as the crisis unfolds.
We don't create maps per se, what we do is to depict the situation on a map as a crisis unfolds. An important part of our service is that we update our maps at regular intervals, daily or more frequently, in accordance with changes in the dynamic situation pertaining at the time. Our baptism of fire came in response to the Asian Tsunami Disaster when a team was scrambled at short notice to help map disaster relief efforts in Sri Lanka. Since then (December 2004) MapAction have completed over 60 missions in both disaster relief and capacity building.
Our capability is predicated on responding to a sudden onset disaster, though MapAction can and do get involved with other types of humanitarian relief activities. We have operated during famine in Lesotho, conducted development work in Tajikistan and we are currently working in Malawi.
This seminar will introduce MapAction and talk through sudden onset and capacity building projects undertaken by Vickie Shelley in Lesotho, Sri Lanka, Tajikistan, Mozambique and Iraq.

Title: A Ground, Airborne and Satellite Study of Snow on the North Slope of Alaska
Ground-based meteorological observations are sparse at high latitudes and so only provide limited data for constraining numerical weather forecasts, evaluating climate models and monitoring climate change. Assimilation of data from microwave sounders on polar orbiting satellites has been found to greatly improve forecast skill in polar regions. Because microwave scattering by snow on the ground is not yet well-understood, however, measured radiances in channels that are sensitive to both atmospheric and ground conditions are not currently used over land.
In February 2008, the NERC atmospheric research aircraft flew out to Fairbanks, Alaska, to join a NASA project combining airborne and satellite observations with ground measurements of snow properties on the North Slope. The ground survey crew, based at the Toolik field station, included one rather cold and food-poisoned researcher from Edinburgh. This seminar will present results from the experiment and discuss plans for using the data in improving snow microwave emission models for use in retrievals of both ground and atmospheric properties from remote sensing. Some cool pictures of snowy landscapes will also be shown.

Title: Tropical Forests and Global Carbon Cycle: Watching Human Impacts and Climate Perturbations from Space
Tropical forests play a key role in the global carbon cycle by contributing to atmospheric carbon concentration through deforestation and land use change and by sequestering carbon at a higher rate than previously expected. The remaining forests in tropics are currently at risk because of increased anthropogenic activities and impacts of climate change to a potential near-term tipping point. Regional analyses from satellite observations are providing us with new insights in patterns and processes of human impacts, forest ecology, and interactions with climate perturbations. These observations include measurements of forest cover, structure, moisture, phenology, and regional climate variables. Recent results from these measurements over the Amazon and Congo Basins draw a new picture of the role of tropical forests in global carbon cycle and pose interesting questions for future research.

Title: Where's the Wind: Offshore Wind Power Planning and Remote Sensing
Download Recorded Talk (WMA File - Right Click, Save Target As)
The UK has an abundant offshore wind resource with offshore wind farming set to grow rapidly over the coming years. Optimisation of energy production is of the utmost importance and accurate estimates of wind speed distributions are critical for the planning process. Synthetic aperture radar (SAR) data can provide synoptic, wide area wind field estimates at resolutions of a few kilometres and has great potential for wind resource assessment. The key challenges for the operational implementation of SAR in this context will be considered; namely the accuracy of SAR wind retrievals and the ability of SAR to characterise the mean wind speed and wind power density. We consider the main stages of SAR wind retrieval; the retrieval algorithm; sources of a priori information; the optimal configuration of the retrieval system; and the challenges for and accuracy wind resource estimation from SAR.

Title: Red, White and Drunk All Over: A Wine Soaked Journey from the GIS Lab
In the real-world of wine making, GIS has a reputation for complex and expensive technology run by computer nerds walking around vineyards with what resembles E.T. strapped to their back. Unsurprisingly, vineyards have been slow to adopt this technology even though it has been proven to save thousands of pounds. Interestingly the slow rate of adoption of new technology in the vineyard contrasts with the high rate of adoption in the cellar, but it doesn't have to be this way.
One of the hottest areas of GIS application is precision viticulture (PV) which can be thought of as a viticultural version of the Motorola’s Six Sigma approach, which attempts to measure, understand and eliminate process variation and hence reduce costs and raise quality. PV has been shown to deliver real commercial benefits when focused towards modifying cultural practices, particularly in reasonably homogeneous viticultural environments, such as are often encountered in Australia or parts of the US, where the aim is to optimise yield and to surpass a quality threshold rather than to maximise quality per se.

Title: The Application of Poverty Maps on Urban Planning: The Use of Census Microdata in Liberia, Costa Rica
Poverty analyses should be instrumental for a pro-poor urban planning practice, yet they are weak in addressing the causes of poverty at city level in developing countries, because they are seldom articulated in a strategic set of pro-poor local actions, and they do not reach small geographical scales at city level where actions should be implemented.
In an attempt to bridge this methodological gap, a technique for undertaking poverty analyses at city level was tested in the analysis of the implementation of Costa Rica’s social housing policy in the medium-sized city of Liberia. It was found that the use of an urban residential segregation approach in small geographical scale poverty analyses allows defining concrete deprived urban areas and foreseeing scenarios to propose feasible pro-poor land-based actions; therefore, proving helpful on promoting a pro-poor urban planning practice.

Title: War and Peace? The Troubled History of the Geo-Data Wars
Once geographic information was considered either a public good, placed in the public domain as most other scientific information, or as a state secret hidden from view to gain military or state advantage. However in the digital age, which effectively started for geographic information in the late 70s and early 80s, geo-data has increasingly begun to be seen as a private commercial resource, even by government agencies which, while publicly owned, still need to recover some or all their costs through trading in such information.
More recently the reduction in the cost of mass data capture, the arrival of commercial global players such Navteq, Tele-Atlas and Google as well as a growing open-source geo-data movement, suggest that the balance of power in geo-data may shift. In this talk Bob Barr will assess how we got to the present unfortunate state of affairs regarding geo-data in the UK, will suggest ways forward drawing on examples from overseas, and will question the possible impact of the European Inspire initiative on the situation.

Title: Active Tectonic Studies in Western and Central Mongolia
Western Mongolia - and adjacent parts of China, Kazakhstan and Siberia - accommodate ~10 mm/yr of the shortening between India and Eurasia and are an important component in this evolving continental collision. I describe recent (and on-going) studies of the late Cenozoic tectonics of Mongolia that aim to understand both the present-day distribution of mountain-building in Mongolia, and the evolution of faulting that has led to that present-day distribution, with application in many deforming parts of the world. The studies range from investigations of the the total deformation recorded in the geology, through the slip-rates on active faults averaged over timescales of 10-100 ka, to the distribution of strain recorded by earthquakes. Although Mongolia has produced several large magnitudes events over the last 100 years (including the Bulnay earthquake of 1905: the largest known earthquake from the continents), these are not widespread over the country, and we have few constraints from seismicity on the deformation in large parts of the country. We are, however, fortunate that the extremely low rates of erosion in Mongolia allow the preservation of surface ruptures from palaeo-earthquakes occurring over at least the last 1000 years: providing a much longer record of earthquakes than available in most deforming parts of the world, and providing information on the sense of motion and slip-direction on the faults.

Title: Thematic Mapping with Remote Sensing Satellite Networks
Currently most remote sensing data gathering is carried out using a small number of sensors of a small number (perhaps tens) of satellite platforms. With falling hardware and imaging costs it is likely that much remote sensing in the future will be undertaken by large swarms of very small satellites, each with limited imaging capacity but capable of operating cooperatively to provide a high level of intelligence in data acquisition. Such networks of satellite sensors present particular analytical challenges when seeking to map the landscape. In particular, we still need to understand how to do thematic mapping in such a context. After reviewing candidate multi-sensor and multi-source classification processes, methods that show promise for operating in the dynamic satellite sensor network environment will be identified. It is concluded that fusion procedures operating at the level of labelled pixels, rather than those that seek to fuse data, offer most promise.

His research tries to show how far understanding the patterns to people's lives can be enhanced using statistics about the population. Part of this research involves developing new techniques to analyse and popularise quantitative information about Human Geography. In particular, introducing the use of novel cartographic techniques into geographical research.

Title: Mapping and Monitoring Millimetric Ground Movements from Space-PSinSAR
In the early 2000s, following almost a decade of using differential interferograms to observe centimetric ground movements, particularly for earthquakes, the Polytecnico Milano, and its spin-out company TRE, pioneered a new processing approach which has yielded results at a millimetric scale (PSINSAR). With around 30 radar scenes utilized, rather than two, a longer term, high precision view is obtainable, with widespread applications. These range from monitoring deformation in earthquake and volcanic zones, ground vulnerability mapping and landslide risk assessment, to geotechnical issues in relation to groundwater abstraction and recharge, compressible soils, mines and engineered excavations. Differential subsidence observed in alluvial flood plains can lead to improved flood risk assessments as is evident from the application of this Persistent Scatterer INSAR technique in New Orleans.
In order to build more awareness of this potential, the European Space Agency has sponsored a project, entitled GMES Terrafirma, to capitalize on its ERS1, ERS2 and ENVISAT data archives. Many city and landslide sites in Europe have already been processed to reveal their ground movement histories for up to 14 years, and by the end of 2008 it is intended that every European Union country will have at least one city, with satellite radar coverage processed to reveal small ground movements of around 1 millimetre per year. That information will be in the hands of national geoscience centres and engineers for expert interpretation utlilising their own data and expertise. They, in turn, will engage with the relevant authorities in their countries to ensure take up, and action on the hazards revealed which will be seen in great detail; in many cases, for the first time. It is intended that these national cities will lead to national initiatives for further studies across each country, and that the examples will be shared across borders to ensure that the community of Europe benefits from the experience of its collective experts and from our European Space Agency’s investments in leading edge technology for practical purposes.

Title: Spatial Data Modelling - The transformation of OS MasterMap to 1 : 250 000 scale database
Intuitive and meaningful interpretation of geographical phenomena requires their representation at multiple levels of detail. This is due to the scale dependent nature of their properties. Considerable interest remains in capturing once geographical information at the fine scale, and from this, automatically deriving information at various levels of detail and scale via the process of map generalisation. Prior to the cartographic portrayal of that information, model generalisation is required in order to derive higher order phenomena typically associated with the smaller scales.
This research presents a model generalisation approach able to support the derivation of phenomena typically present at 1:250,000 scale mapping, directly from a large scale database (1:1250/1:2500/1:10,000). Automatic derivation of the required geographic phenomena requires that we model various relationships among the objects in the database. This research focuses on two types of relationships: taxonomic and partonomic. The research demonstrates the importance of both of these in the transformation of spatial objects in the source database into required objects for the target database.
The utility of the results obtained, via the implementation of the proposed methodology, is demonstrated using spatial analysis techniques and the creation of 'links' between objects at different representations needed for multiple representation databases. The output database then acts as input to cartographic generalisation in order to create maps (digital or paper). The results are evaluated both quantitatively and qualitatively using with manually generalised datasets.

Title: GIS and Crime Mapping
Crime has an inherent geographical quality. For a crime to occur it involves an offender and a suitable target to come together at a place, at some point in space and time. Understanding the role that this 'place' has and the importance of other geographical factors that result in why a crime occurs can offer vital clues that contribute to improving how we respond to and tackle crime problems.
Crime mapping is the direct application that comes from considering the inherent geography in crime. It also involves much more than just the production of pretty hotspot maps for management reports and the office wall. Crime mapping particularly contributes to the intelligence development process, helping to generate a real understanding of criminal activity and the direction in tackling it.
This presentation will explore this inherent geographical quality to crime and illustrate how GIS, geographical analysis and spatial thinking is contributing to supporting improvements in policing and partnered crime reduction activities.

Title: Changes in Elevation of the Amery Ice Shelf, East Antarctica, over 40 years ... plus some GRACE results
Antarctica's ice shelves are sensitive to changes in both ocean and atmospheric conditions and thus may represent "early warning systems" for climate change effects in Antarctica. Furthermore, their potential role in regulating the flow of onshore ice onto the sea (and thus influencing sea level) has been dramatically demonstrated in the case of the Larsen B Ice Shelf. Recent satellite altimetry results have shown that, between 1992 and 2001, Antarctica's ice shelves exhibited mean elevation trends (dh/dt) commonly in the region of +-0.2m/yr, with a few much larger exceptions. However, over periods as short as ~10 years, regional environmental variations may mask a longer-term (in)stability. The main part of the talk will discuss one of the longest spans of velocity and elevation change data for a large Antarctic ice shelf, the Amery Ice Shelf in East Antarctica. The Amery Ice Shelf data set, starting in 1968-69 provides a truly multi-decadal data span, placing these shorter data sets into context and highlights some curiosities in the altimetry record in that region.
The final, shorter, part of the talk will report on an investigation into aliasing of ocean tides into GRACE (satellites measuring Earth's gravity field) time variable gravity fields around Antarctica, and hence GRACE-based ice mass balance estimates. It is shown that some tidal constituents are aliased into ~3 and ~7 year terms and that published GRACE results will be biased by tidal mismodelling. The most recent release GRACE products, using a more accurate (but not perfect) tide model, are much improved but further improvements are required.

Title: Place-based versus people-based accessibility
Accessibility is core to many theories and methods addressing many social, economic and urban phenomena. Traditional methods for measuring
accessibility focus on the spatial separation between key locations in individuals' lives such as their home and workplaces. These are
place-based accessibility measures since they are functions of locations rather than people. While still viable and useful, place-based
accessibility is increasingly incomplete. A place-based approach to accessibility by itself is no longer viable in a world where transportation and communication technologies are drastically changing the relationships between people and place. The continuing development
and deployment of geographic information systems (GIS) and other geospatial technologies are greatly enhancing the ability to collect and
analyze data relevant to accessibility analysis. This lecture argues that traditional, place-based measures of accessibility should be
enhanced and complemented with people-based measures that are more sensitive to individual activity patterns and accessibility in space and
time. I will also present some of my work on developing people-based accessibility measures in network, multi-dimensional and virtual spaces.

Title: An Agenda for Geospatial Intelligence Research
The Centre for Geospatial Science at the University of Nottingham was launched in November 2005 with the objective of undertaking
research into geospatial intelligence, geospatial interoperability, mobile location-based services and aspects of telematics. Its remit is
to undertake mid-term research in these areas directed at addressing major topics of governmental and industrial concern and with a
particular applications focus in the area of disaster management, mitigation and recovery.
The presentation covers the progress of the first 18 months including the identification of technology drivers and definition of
the research agenda. The outcome has been the creation of a highly multi-disciplinary research group crossing both traditional areas of
concern to the GI scientist as well as the incorporation of strong computer science and human factors elements. Whilst the research
horizon is mid-term it has been necessary to consider longer terms trends in a number of fast moving technology areas to try to ensure
that energies are spent on what will be tomorrow’s problems rather than today's passing inconveniences.

Title: Recent sea level contribution of the Antarctic and Greenland ice sheets
After a century of polar exploration, the past decade of satellite
measurements has painted an altogether new picture of how Earth’s ice
sheets are changing. As global temperatures have risen, so have rates
of snowfall, ice melting, and glacier flow. Although the balance
between these opposing processes has varied considerably on a regional
scale, data show that Antarctica and Greenland are each losing mass
overall. Our best estimate of their combined imbalance is about 125
gigatons per year of ice, enough to raise sea level by 0.35 millimeters
per year. This is only a modest contribution to the present rate of
sea-level rise of 3.0 millimeters per year. However, much of the loss
from Antarctica and Greenland is the result of the flow of ice to the
ocean from ice streams and glaciers, which has accelerated over the
past decade. In both continents, there are suspected triggers for the
accelerated ice discharge—surface and ocean warming, respectively— and,
over the course of the 21st century, these processes could rapidly
counteract the snowfall gains predicted by present coupled climate

Title: GIS: Objects Are Not Enough
GIS theorists for the last 20 years or more have failed to respond to the challenge of Leibnitz that space is the expression of the relationships of objects embedded within it, or to Einstein's comment that empty space has no meaning.
They have failed to look at the dimensionality of the objects they implicitly embed; they have accepted that connectivity is a "hard" problem best left to commercial outfits and computer scientists; they have failed to look at spatial relationships other than superimposing objects; they have failed to treat fields seriously, relegating them to trivial rasters; and they have retreated to their last defences of discussing only things that may be chopped up and put in databases.
If we want to be scientists we must pick up the challenges of the hard problems again. If spatial data is information that has no meaning separated from its location in space, it is evident that its relation with other information at other locations is fundamental to any understanding of the world we live in. We must reach beyond our own narrow discipline (that we think is broad because so many things are geography) and seriously woo the many disciplines that involve spatially-realizable objects. We must go back to looking at the stars and asking: "What is Space?"

Title: Sharing Spatial Information Within the SEERAD Family
Enterprise level GIS and spatial data management has become the norm in central government organisations today. This has been driven by the high cost of data licensing and the mainstreaming of GIS technology. The next logical step is to cross the corporate firewalls and begin sharing spatial information services between organisations.
In 2005, the Scottish Executive Environment and Rural Affairs Department started work on implementing a corporate GIS infrastructure that would allow the efficiency gains from enterprise level GIS to be extended to a multi-agency environment.

Title: Is there a theory of Geographic Information?
Much research in geographic information science has been technical, but pursuit of theory can increase the perceived and actual value of Geography and geographical information to other disciplines, and so a theory of geographic information is a desirable research goal. Models of information theory from computer science, primarily following Claude Shannon’s entropy concepts, have provided a background, but a new approach or paradigm now seems necessary. Fortunately, geographical representational models are well developed and formalized, even standardized. Yet in terms of abstract information, beyond Shannonian content, spatial data must also account for spatial relations, process and time within the geographical geometry; and also must communicate confirmation, level of detail, relations and pattern. I review the first fragmentary precursors to a new theory of GI, suggest that missing elements are links to energy and matter, and conclude that the lack of a theory will eventually hamper GIScience as we drown in the vastness of data now coming on-line, since not all geospatial data are of equal scientific value.

Title: New ways of Looking at the World: A Sample of Research at the National Centre for Geocomputation
Advances in technology are allowing unprecedented access to large volumes of spatial data; a situation that challenges us to find innovative methods of converting such data into useful information. This seminar will cover three aspects of geocomputation as currently being practised at the NCG. One concerns spatial data capture through GPS-linked sensors with an example given of digital video; a second concerns the visualisation of spatial data through continuous cartograms with an example shown of Irish population dynamics; and a third demonstrates the measurement of spatial varying processes through Geographically Weighted Regression. Some introductory remarks will also be given about the NCG. Stream Recording (Windows Media Video)

Title: GIS and Public Sector Reform "The Local Government Perspective"
Over the last 5 years, the public sector has undergone significant change in the modernisation and reform of its services. Over the same time, there have been signifcant changes in GIS technology and the geographic information marketplace. This talk considers the changing backdrop to the delivery of public sector services in Scotland and how
the role of GI/GIS is supporting the development, transformation and sharing of efficient public services as well as some of the key organisational and technical challenges ahead.

Title: Spreading Gain, Spreading Pain: Modelling the impact of the hyper mobile classes at multiple scales in Aotearoa New Zealand
On the surface the core of this presentation is the phenomenon of the growth and changing impact of international tourism in New Zealand, a country with a number of similarities to Scotland. Certainly the talk will offer a substantive look at the growth trajectory of tourism and its geographic manifestations, but behind this is a concern with a far wider agenda. That agenda is centred on the need to explore ways to describe, visualise, generalise and model individual flows, and beyond that to identify structural patterns in those flows, and the impacts of those flows on the geographies they traverse. At the very heart of this is the better understanding of spatial processes that stretch from financial flows to disease transmission, and embrace the enterprise of achieving a more dynamic view of human GI Science. This seminar will elaborate on the methodologies being developed for exploiting New Zealand's national data bases, and conclude with a comment on the opportunities for dynamic GIS.

Title: Geographical Health Variations in Scotland
This talk considers health inequalities in Scotland over the last two decades. The relationship between deprivation and mortality is considered in detail, and the evidence for the 'widening health gap' is discussed. We also explore how mortality variations relate to population mobility and compare the health of the Scots with English and Welsh people living in Scotland. Finally, we focus on the example of suicide and explore how the health gap has widened, but also whether there is any evidence of suicide clustering in Scotland.

Title: Remote sensing of forest cover: new techniques and opportunities or potential that is always just out of reach?
Several factors appear to have come together to encourage the development of new ideas and techniques in remote sensing for forest cover assessment. Such factors include concerns over the role of land cover change in climate change, the demand for better information on biodiversity and also commercial concerns over the cost of managing forests at a time when timber prices are low worldwide. In many countries, including the UK, there is recognition that remote sensing can help to deliver quantitative data over large areas in a way that is reliable and cost effective.
The seminar will use examples from forest mapping studies in Bangladesh, New Zealand, Sweden and the UK to illustrate the potential of fine spatial resolution optical imagery and airborne LiDAR. There will be a discussion of the potential to model tree height, volume and even in some cases species using innovative techniques such as LiDAR; there will also be an acknowledgment that there is still much work to be done to link remote sensing to biophysical models for forest growth on the one hand and commercially useful mapping techniques for the forest industry on the other.

Title: Some issues in the development and application of geodemographic profiling
Geodemographics, the analysis of people by where they live, is undergoing a renaissance in public sector applications, particularly in education, health and policing. In that geodemographics provide measures of neighbourhood conditions that connect with individual and household circumstances, they also have important roles to play in promoting spatial literacy, in effecting knowledge transfer of the core organising concepts of the discipline of Geography, and thence in halting the continuing decline of the discipline in UK education and research.
This seminar will develop and illustrate these issues with respect to:

Prof. Jim Frew
Visiting Professor, School of Informatics, University of Edinburgh
Title: Computational lineage of satellite-derived data products – first steps
Jim Frew is Associate Professor in Environmental Information Management at the Donald Bren School of Environmental Science and Management, an interdisciplinary graduate school based at the University of California, Santa Barbara. During this last year, he has been a visitor to the UK Digital Curation Centre and the Database Group at the School of Informatics at the University of Edinburgh.
His talk will feature a review of his recent work designing web-based information systems to deliver satellite-derived data products (for example, water content estimates for snow-covered mountain ranges) to their scientific users. A prominent feature of his system architectures are in-built methods to record and allow queries on the provenance (lineage) of each custom data product. This provenance information is key to capturing the algorithms behind derived data, and is critical for curating (properly managing and archiving) scientific data collections for the long-term.

Title: Landscape simulation and monitoring, linking data to use
Pressures for change in the rural and peri-urban landscapes of Scotland lead to the use of complex and equivocal data and information in the advocacy, or rebuttal of changes in land use, management practice, or regulatory control. This in turn can lead to misinterpretation of the reasoning or objectives of such change, or the likely directions of change (e.g. following the uptake of CAP reform and opportunities under the Rural Development Programme or pressures for a diversity of energy supply).The role of scientific research in the provision of an evidence-base for management decisions at a range of scales (e.g. city park, farm, estate or region) requires data, or knowledge, in the form of inventory, interpretation and a means of exploring options.
Studies of landscape change, for which tests were conducted on the role and effectiveness of visualisation tools in presenting scenarios of change in urban and rural landscapes are used to discuss the value of such tools in aiding public participation in decision regarding land use and landscape change. The presentation will consider how visualisation techniques can be used for testing factors associated with preferences for landscapes, and virtual reality tools for use in aiding the advocacy of cases by professional and public stakeholders.

Title: "Understanding and predicting mining subsidence in North Yorkshire, using radar interferometry".
In the coastal area of North Yorkshire, potash is extracted at depths of 0.8 to 1.3 kilometres. The undermined area is approximately 40 square kilometres and is subsiding gradually at a maximum rate of 60 mm per year. Ground surface deformation associated with deep mining activities tends to differ from that accompanying shallower extraction. Prediction of the gradual rates operating over large extents is a challenging problem due to the range of complex variables that combine to determine the deformation of the surface. Complex environmental processes such as mining-induced subsidence can be modelled empirically if large monitoring datasets of sufficient distribution, accuracy and reliability are available.
An empirical model was built based on an alternative data-driven approach using statistical techniques in combination with a relational database, using two datasets. This approach utilises past patterns of monitored subsidence to predict future movements at any point in space and time as a consequence of mining activities. In addition to the existing levelling dataset a new dataset was created using space-borne radar Persistent Scatterer Interferometry (PSI). In her presentation, Ilona evaluates the PSI technique and present an improved method of understanding complex deformation processes.

Title: "The Helpful Environment - geographically dispersed intelligent agents that collaborate"
"Imagine in the not too distant future that every citizen, vehicle, package in transit and other "active devices" can be treated as a potential sensor or responder. Individuals or vehicles that need help, as well as local, regional, national and international emergency agencies, could look up specialized capabilities, or find local availability of help and seek support to enable a much more responsive and effective environment. Systems could inter-operate to enable preventative measures to be taken so that those in imminent danger of natural and other hazards could be forewarned by their own systems, and by the people, vehicles and buildings around them. A truly "helpful environment" could be created that is accessible by all." Talk slides here (Links to external website)
