Basic technical framework of national basic geological database integration

National basic geological data,including all kinds of basic geological data,such as areal geology,geophysics,geochemistry,remote sensing image,geological drilling,regional ocean,hydrogeology,mineral resources.Due to the physical dispersion,different database standards,too dependent on the business system and other reasons,these data are difficult to meet the demand for public,professional organizations,and managers.In order to improve the national basic geological data sharing and service,during in-depth analysis,experiment,and synthesis,based on the technology of metadata,database,data warehouse,GIS,Internet and web technology,the paper proposed basic technical framework of national basic geological database integration with physical distribution and logical collection
