Abstract Using the VB program, the authors converted the Regional Exploring Data point information into a MapGis Point Document in plain code, and set up a database which joins the Point Document to the exploration data. Exemplified by the 1:200,000 Regional Exploration Data of Hebei Province, this paper has established a provincial regional exploration spatial database, which makes it possible to carry out such spatial analyses on MapGis as intersection analysis of geological areas, condition inquiries, and analysis of buffer areas. As a result, data inquiries can be easily made in spite of spatial restriction or geological conditions, and various geological problems related to mineral exploration can be solved.
