Interoperating GIS: Overview
可互操作的GIS研究

With the reality of computer is the network, through the platform, accessing the information, particular geoinformation independent of data structure, semantic and so on is the dream for the users. Inter-operating GIS is the hot topic due to the useful way to realize it. In this paper, we focus on the overview of inter-operating GIS. Technology interoperation is to access and share geodata, service interoperation is to access useful geoprocess and operation, and semantic interoperation works on how to get the true geodata and geoprocess what the user want. Technology, methodology, state and drawback have been present in these four aspects. Finally, the future of inter-operating GIS is expected.
