V The merger of Geographic Information Systems (GIS) analysis with multidimensional visualization has S allowed the development of a unique interactive environment for GIS systems. Instead of the traditional top down viewing of GIS layers and analyses using those layers, a three dimensional approach is Curr described that combines GIS functionality with a fast 3 dimensional code developed at the Georgia Tech view Research Institute (GTRI). While three dimensional perspective viewing has been common in flight spati simulation and has been used recently in display of remote sensing and GIS data sets, it has always been dime used primarily as a glitzy method to display basic data and pregenerated analyses. By combining fast be p rendering within a GIS structure, direct query of attributes can be added to visibility analysis allowing using the practical use of perspective imaging as a direct interface into a GIS analysis system. This interface and : is a natural method for a user to interact with spatial data sets. the s the @ from I.
