Abstract:

National mineral resource potential assessment, the survey for utilization of national mineral resource and the national mining rights field verification are the three nationwide projects for basic national conditions survey in the field of mineral resources. They contribute more than 10 Tb geological information data. Boosting the integration and share of geological data is conducive to promote the service abilities for prospecting breakthrough strategy action，enterprises and community. The authors propose the geology information one-map idea after have analyzed the data integration requirements of three survey result data with typical massive and heterogeneous characteristics.The study about sharing and application launched from data integration and application integration. The various clients can use geological data resources and computing resources by service interface. Users can complete the following businesses online through GUI：geological data access，analysis，fusion show and thematic maps generation. Recommending two new kinds of geological material service types：one is provide information on demand online，another is submit the request online and process data offline to produce new geological products. The integration and sharing trial platform of the three specialized projects is built preliminarily using regional outcomes data of gold and iron ore as basic data objects，and using GIS components to implement the prototype system. The system can achieve spatial data analysis and all kinds of maps generation with automatic configuration cross projects flexibly. The solution is operational and it is able to contribute valuable references for the nationwide integration and land resources one map.
