Land use data are usually collected by the basic unit of county, but they must be realized the integrated application at municipal level, provincial level and national level. In this paper, we research on the integration technologies of distributed land use data based on OGC standards-compliant geospatial grid services. Firstly, we analyze the integration demands of distributed land use data and propose the integration objectives. Then, we research the integration mechanism of distributed land use data based on OGC-Compliant geospatial data grid service. Lastly, we realize the municipal level integration of distributed land use data of two counties.
