TOPIC: WHEN DISCIPLINES MEET: VORONOI METHODS IN GEOMATICS DATE: Thursday, February 8, 1996 TIME: 1:30 p.m. PLACE: Room 5115, Herzberg Building Carleton University ABSTRACT Occasionally, a new technique appears that has the potential to significantly modify a discipline. At present it appears that recent developments in Voronoi diagram methods in Computational Geometry have the potential to change many of the ways we look at spatial problems in the discipline of Geomatics, or Geographic Information Systems (GIS). In an attempt to escape from some of the limitations of traditional GIS data structures, the Voronoi diagram is an attractive alternative - it is a space-filling structure, eliminating many problems of the line-intersection spatial model. It has various forms in various dimensions, and by making it fully dynamic the traditional GIS operations may be extended in new directions. A variety of GIS-type problems will be described, along with possible solutions. The real challenge for the future is not only to implement more efficient versions of traditional GIS functions, but to see how the two disciplines may combine to produce completely new functionality.
