CLUES : a web-based land use expert system for the Western Cape

[摘要] GIS has revolutionized geographic analysis and spatial decision support and has greatlyenhanced our understanding of the real world though it's mapping and spatial modellingcapabilities. Although GIS software is becoming more powerful, less expensive and more userfriendly,GIS still remains the domain of a selected few who can operate and afford thesesystems. Since the introduction of web mapping tools such as Google Earth, accessibility togeographic information has escalated. Such tools enable anyone with access to a computer andthe Internet to explore geographic data online and produce maps on demand. Web mappingproducts have, however, a very narrow range of functionality. In contrast to GIS that focuses onspatial data capture, storage, manipulation, analysis and presentation, the function of webmapping tools is to visualize and communicate geographical data. The positive impact of webmapping tools suggests, however, that GIS has not yet developed to a level where anyone canuse the technology to support spatial decisions and enhance productivity. A possible solution isto close the functional gap between web mapping tools and GIS to make spatial analysis moreaccessible, thereby promoting geographical awareness and supporting better spatial decisions.
