摘要：Recently, GIS related research and applications have been making rapid progress. Computers with faster CPU and larger memory enable practical applications of time consuming and memory intensive algorithms, both for spatial analysis and visualization. Storage devices become cheaper and have larger space to store data of larger volume and more varieties including image, sound and video. For GIS data capture, novel technologies such as GPS, laser range finder, synthesize aperture radar are getting more and more popular, which bring us terrain data of higher precision at lower cost. Yet, our living environment is also changing rapidly, which makes it a task of high cost and complexity to maintain and manage geometric data such as cartographic or utility information. This paper proposes a system for efficient GIS data maintenance and management. It makes use of a spatiotemporal data model for describing various types of dynamic changes of GIS data, manipulating data in multidimensional space including time. The experiments performed on the initial implementation of the proposed system show its ability of efficient and accurate maintenance of dynamic GIS data.
