The development process and technique of the mineral resources potential evaluation data model in China

Abstract：Exemplified by data modeling of China's mineral resources potential evaluation special project,this paper put forward the development process and implementation strategy of the data modeling for the very complex problem domain,systematically illuminated the essential contents of the development process and implementation strategy of the data modeling,briefly introduced the design idea,the methods and techniques,and the related research achievements. Practices have verified the effectiveness,feasibility, practicability and representativeness of the development process, methods and techniques, and the results obtained have certain reference significance and application value. The achievements are especially suitable for large quantities of geological project data resources construction characterized by super-large,multi-professional,engineering and spatial-oriented data.
