Abstract: Based on detailed discussion of the current status of geospatial information resources application and development of geospatial information technologies,this paper proposed a geospatial information service mechanism supported by multi-tier heterogeneous geospatial databases.By providing and calling WMS,WFS and other standard geospatial services built on distributed and cooperated databases,this mechanism provides a total solution for the state-wide geospatial data integration,sharing and services.
