Study for the Interoperable Model of GIS Based on Web Services;

Firstly, this paper introduces the necessity and technology of GIS interoperability generally , then gives a detailed description of the main function core module and the advantage of the GIS interoperability in Feature Manipulation Engine (FME), then, extends the interrelated interoperability technology of FME taking the example of the transformation between DGN of CAD and Tab of Mapinfo.

It is necessary to realize geographical information sharing and GIS interoperability for GIS application socially.

In this paper, we realize GIS interoperation at syntactic and semantic levels by encapsuling geographical function unit in semantic geographical web service, and describe how to interact with it with WSDL and what its geographic function means with OWLS, then present an interoperation model of semantic geographical web service.

Construction of distributed workflow interoperation model based on SOAP technology;

This paper introduces the basic concept and key technique of cross-platform interoperable GIS, and discusses its present development status and technique evolvement in our country.
