This paper will be based on a NASA project with the City of Boulder CO. The goal was to obtain better productivity through GIS, particularly n the area of city planning and in offering new services to the public. One of the techniques used was to create animation loops (4-D GIS) of maps of the areas of interest. The ArcInfo TINS module was used for visualization, and then successive maps were linked together to show different perspectives. The goal of the current research is to evaluate the impact that 64-bit ArcInfo and 64-bit UNIX will have on the productivity of this process. At the moment it is extremely time-consuming (some of the processing is an overnight run, depending on how many scence are involved, etc.) We think that animation is an important new use of GIS and hopefully this paper will inspire other ArcInfo users to try it. NASA's Commercial Remote Sensing Program Office at Stennis Space Center, in Mississippi recently tested 64-bit computing for a number of frequently used digital image processing (DIP) techniques. Using multispectral imagery acquired from NASA's Airborne Terrestrial Applications Scanner (ATLAS), ancillary data, ERDAS Imagine 8.2 software, and ArcInfo, operation times for DIP procedures were recorded and compared to the operation times achievable on a 32-bit platform. As a capstone to this examination, three-dimensional fly-throughs were obtained by capturing successive images from slightly different viewing perspectives. The perspective images were then viewed in succession using movie emulation tools. The authors would like to demonstrate this technique in an Application Spotlight at the conference.
