In order to improve the accessing precision of polar geospatial information service on web, a new methodology for retrieving global spatial information services based on geospatial service search and ontology reasoning is put forward, which includes distributed geospatial web service , geospatial service search engine, extended UDDI register center and multi protocol geospatial information service client. Some key technologies including service discovery based on search engine, service ontology modeling and reasoning, and service register based on extended UDDI are presented. Finally, the prototype is described.
