|Voronoi methods in geomatics--the importance of the spatial model|
Geomatics covers surveying, remote sensing, geographic information systems ( GIS) and other topics concerning the capture and management of spatial information. Thus the restricted (discrete) model of space used in the computer is of central importance. While known for many years, the simple Voronoi diagram is only now being recognized as a central organizing concept for many types of data. This has been helped by the discipline of Computational Geometry, and is now being recognized within Geomatics. This talk will focus on applications based on simple concepts, and show how the Voronoi model is ideally suited to both algorithm development and geographic data input, management and analysis.
The plenary address will survey some of the classical examples of these moduli spaces and their structures. The special session talk will describe some of the more technical details of the proof.
