Using GIS To Illustrate Two-Dimensional Groundwater Contamination on a Three-Dimensional Platform
Defining Issue: Groundwater contamination is very difficult to communicate to the public when displayed in two-dimension. The challenge would be to create informative animations and images that clearly show the public the extent and treatment of groundwater contamination. GIS Solution: The San Gabriel Basin Water Quality Authority has been actively involved in the Federal Government's Superfund. A three-dimensional application was used to better communicate to Congress and the Environmental Protection Agency how the groundwater cleanup can be expediated. This application converts the contamination polygons, in ArcView, to Virtual Reality Modeling Language, then was able to be viewed using a browser and animated for final production on a video clip. Also, a set of maps were specially created so that they could be seen three-dimensionally using special three-dimensional glasses. Methodology: The Avenue script that converts polygons to VRML was modified so that it would create the blobs of
groundwater contamination in three-dimension. Along with a three-dimensional model of the contamination is a set of maps created specifically to be viewed using special three-dimensional glasses. Using these glasses an observer can see, in three-dimension, the depths of the contamination concentration levels below the surface; without the glasses the map appears to be just another map. Software: The application was written with Avenue and VRML. The purpose of this paper is to demonstrate how a low budget agency can communicate a three-dimensional concept using different methods.
