Abstract: In consideration of the requirement of metal deposit prospecting and construction of land resources information, the metal deposit prospecting and exploration information was summed up through scientific and rational filtration and induction, and then the design programs were made, which were made up of three subsystems: information collection subsystems (client), information retrieval system (client) and network database services (server), including seven main modules: attribute information collection module, space information collection module, original data collection module, data maintenance module, attribute information retrieval module, space information retrieval module and original data retrieval module. A metal deposit prospecting and exploration system having a friendly customer interface was developed adopting the integration development method of VB + MapGIS components + SQL Server, which can serve for the geological exploration departments, government departments and the public. The VB code of some technical issues settled in project development process was also given.

Key words: exploration, information system, construction of country resource information, MapGIS development
