Wu Chonglong (Institute of Geology and Mineral Resources Information System, China University of Geosciences, Wuhan430074)  
An integrated geological and mineral resources point-source information system (GMPIS) consists of three parts: exploration data management, exploration data process, and geological-mineral resources prediction-evaluation. It has a stromatolithic compound structure of technique-method and application model with its core of point-source subject database. This system has unified data model, standard code system, normative procesing pattern and integrated function software. Except what is mentioned above, it even has open development flat-top of application software. They are not only providing various interfaces which accept new achievement of function software momentarily, but also are able to support all users to undertake additional redevelopment expediently at their particular requirement. Geological and mineral resources point-source information systems are established on the basic exploration units (data collection locales). They can combine two goals: actualizing computerization of data collecting and processing in all geological-mineral exploration course, and actualizing computerization-networked of management and retrieval of geological-mineral data. It can be not only network intersection points of national geological-mineral information, but also micro-workstations of basic exploration units. The development objective is to actualize the association of ‘5 bases’ (database, graph-base, model-base, method-base and knowledge-base) and integration of 6S (DBS, GIS, RS, GPS, CADS and ES) in the future.
