| Abstract: | It is the GIS developing direction to integrate GIS with Internet. Internet GIS is not only used to publish distributed geographic information on line, but also to provide on line tools for distributed geographic information real time analysis and processing. Internet GIS should make use of existing multi sources and functions for geographic information analysis and processing. In other words, it must solve the problem of interoperability. The interoperability of Internet GIS includes heterogeneous data and heterogeneous geographic information processing environment. This paper provides the Internet GIS approach to interoperability of heterogeneous geographic information processing environment, and the interoperability based model, distributed hypermap model, for Internet GIS. The implementation of this method is made clear. With the example of Internet GIS GeoSurf, it sets out the application of this method in details. |
