A Research Of Spatial Information Integration And Share Based On Ontology In Resource And Environment Field

As the spatial information technology is applied deeply in resource and environment domain it produces many separate and different structures of resource and environment spatial information that are respectively independent, relatively isolate and unable to interoperate. The information forms isolate spatial information island so that it is difficult to meet the requirements of related and comprehensive policy for Internet and resource and environment spatial information. How to make these spatial information islets respective independence as well as interoperate and how to make Internet users rapidly and accurately locate, attain and use cared spatial information, and so on, are the focus of international spatial information study at present and also are the key of achieving spatial information integration and share in resource and environment domainSo the paper introduce Ontology to research the technology of Spatial Information integration and share; make ontology and web service get together closely and construct research framework of spatial information integration and share based on ontology. Through the deep research of Ontology , practice the applied study of spatial information of resource and environment share and integration and Spatial Information Service modeling construct. The former provide the comprehension of date for the different resource and environment department. The later build the bridge for the user to information , and is the road to realize the Spatial Information integration and share.
