Color Figures from Geographical Information Systems, Second Edition

Plate 01 Spatial representation used to map the areas of darkness and light on the Earth’s surface. ( 1 of 67)	Plate 02 Raster (voxel)representation in a 3-dimensional matrix. ( 2 of 67)	Plate 03 Vector representation of solids using tetrahedra. ( 3 of 67)	Plate 04 Three-dimensional view of the DEM in Figure 5 of Chapter 9 overlaid with specific catchment area. ( 4 of 67)
Plate 05 Annual mean precipitation overlaid on a 250-m resolution DEM for an area of length approximately 25 km. ( 5 of 67)	Plate 06a Mount Kilimanjaro: a topographical view. ( 6 of 67)	Plate 06b Mount Kilimanjaro: a thematic view. ( 7 of 67)	Plate 07 Representing spatial information: Bertin’s (1993) graphical variables: size, value, texture (grain), orientation, and shape expressed in point, line, and area symbols. (Source: Kraak and Ormeling 1996) ( 8 of 67)
Plate 08 Detail from Microsoft’s Encarta World Atlas. ( 9 of 67)	Plate 09 Graphic depiction of the error in a single-elevation value. (Source: Hunter and Goodchild 1995a) ( 10 of 67)	Plate 10 The cross-validation error shown separately from the data in a side-by-side display for two different periods. The cross-validation error is displayed as glyphs (coloured balls on pins) with the colour of each ball representing the error at sampled depths. (Source: Mitasova et al 1995) ( 11 of 67)	Plate 11 Images showing estimated surfaces of dissolved inorganic nitrogen for two time periods with cross-validation error at each observation station. Cross-validation error is displayed as a glyph. The height and colour of the glyph indicate the value of the cross-validation error. (Source: Mitasova et al 1995) ( 12 of 67)
