In the course of updating the GIS database of land use data, the multi-source data always canpsilat match well. In order to update the GIS database of land use data more effectively, scientifically, reasonably and esthetically, based on the GIS data updating quomodo and the practical requirement of land use data updating, a data fusion algorithm of GPS/GIS is presented in the paper. By establishing...
