Abstract：As a basic platform,MAPGIS is widely applied during establishing geological spatial databases in China currently.The quality of its spatial data has a directly effect on the function of the geological spatial database.The precision of spatial data,the validity and intagrality of the attribute data and the topo relation of spatial data are the main factors that affect the quality of space database.Based on practical work,the methods for data quality control are studied.With the methods,the data quality can satisfy the request for the establishing of high standard geological spatial databases.
