            TEST WORKSPACE FOR GEOGRAPHICAL INFORMATION SYSTEMS


OVERVIEW

This workspace contained in this directory is an example of how to connect
the different GIS modules together.  

NOTICE : This workspace will not run!  The required input data files
	 have not been included in the standard KHOROS package.  It
	 is only intended to illustrate how the GIS modules might
	 be connected together.

gis.wksp.Z - will take a satellite photograph, a DLG file
	     (which shows the roads in the area), and a DEM 
	     file (which shows the elevations in the area), 
	     convert them all to VIFF files, and then warp
	     them such that all of the corresponding features
	     in each of the images overlap.  The resulting image 
	     is then displayed in a three-dimensional form.
