摘要：Combined with Spatial data model of MAPGIS, this study brings up distribute structure query language (DGSQL) and has designed the interpreter of DGSQL. This study has given the method of the analysis of the distribute structure query language to the GSQL of the node of the spatial data and built the mapping model of the global spatial query sentence to the local query sentence. Hence, DGSQL can sustain the query of distribute spatial data. This study has realized the spatial relation operation (Intersection, Union, Difference) and synthesized operation (Length, Buffer, intersecting region) and so on.
