Abstract: An approach to geo-spatial information systems considers how to improve expansibility and interoperability, which has become increasingly relevant in this research field.This paper firstly looks at the ISO/OGC rules and standards of geospatial sharing, and then constructs an SOA (service-oriented architecture) geo-spatial integration module.Based on the module, researches the uniform architecture of geo-spatial interoperability and services; forms independent of software and the expression pattern of suit the geological spatial information interoperability.The purpose is to provide a data description mechanism for use in an isomerous and distributing system, making it possible to apply and manage geological spatial data.This paper presents geo-spatial information exchange architecture using the GML (geography markup language) model, aiming at geoscience application demand.The pattern of specialty data is put forward providing a feasible way to ensure geological spatial information interoperability.
