The downloading of data from SWAD and SPA Database
into ArcView was tested on ESRI® ArcView GIS 3.2. If you have any
problems please contact Anthony
Newton, your computing support or ESRI.
For instructions on using ArcMap click here.
These instructions assume a basic knowledge about ArcView. Note that
if you have a choice we recommend that you use ArcMap, as it is far
simpler to import text files and use the hyperlink tool than in ArcView. |

Instructions on importing sites into ArcView GIS |
Downloading data from SWAD and SPA Database: |

After a short pause a dialogue box will appear asking whether you
wish save a file called arcviewfile.txt to disk.
Click on the OK button and save the file to an appropriate
folder. You can rename the file to whatever you want, but keep the
.txt suffix. (Note that file you have downloaded
contains a list of files with XY coordinates as Ordnance Survey northings
and eastings.

Importing arcviewfile.txt into ArcView: |
- Open a new or existing Project in ArcView.
- If a new Project, load a map of Scotland or the part of Scotland

window and click on Add button. An Add Table
dialogue box will appear. Change the List of Files of Type
to Delimited Text (*.txt) and select the appropriate
file to load. Click OK.

Loading a script into ArcView so that Hot Links can be used:
|
- In order to use the Hot Link feature in ArcView a script needs to
be loaded. This tells ArcView to launch your default web browser when
you click on a point. This script needs to be loaded into each new
ArcView project.
- Click on Scripts in the Table of Contents window and then click
on New.
- A new window called Script1 will appear.
- Copy the following text (from theVal to the second
end) and paste it into
the Script1 window. You will need to replace the red
and bold text with the location of your web browser.
In the example below, Internet Explorer is launched, but this could
be Mozilla, Opera or whatever.
theVal = SELF
' see if the value of the field is not null
'trim "/" off the end of hyperlinks
number i = theVal.Count
theValTrim = theVal.Left(i-1)
if (not (theVal.IsNull)) then
' if the file listed in the field exists, then run browser
if (File.Exists(theVal.AsFileName)) then
' use the path to the video player executable
System.Execute("C:\Program Files\Internet Explorer\iexplore.exe" ++theValTrim)
else
' if the file doesn’t exist, tell the user
MsgBox.Warning("File "+theVal+" not found.","Hot Link")
end
end
- Once you have completed the script, click on Script
in the menu at the top of the page and click on Compile.
- Close the script window.
- You can rename the script if you like by highlighting the script
in the Table of Contents window and pressing "Control
+ R" or going to Properties on the
top me.
