1:50000Spatial Database Construction Method,Standard, Process

1:50000regional geological map spatial database is suitable for less than or equal to the same scale of basic geological survey, mineral resources exploration, environmental geological survey or planning etc.. Quality problems of digital production1:5million regional spatial database is generated along with data acquisition, processing and application process. In order to strengthen the digital production quality control and management, ensure the quality of digital production, make the construction project geological map spatial database1:5million regional in the framework of unified standards within the normal and orderly development, this paper take the Qinghai province tin Tieshan building map as an example, the construction method, with the space1:50000regional geological map database the procedure and the existing problems.This paper is on the basis of a large number of1:5million regional geological map of geological survey data, to the domestic software MAPGIS as the platform, and using the GIS spatial analysis function analysis, application software to carry out a comprehensive study on the spatial database has been built, a detailed understanding of geology, mineral content of the work area, to delineate mineralization, ore prospecting the target area, the future exploration and research work has played a guiding role.This paper describes in detail the application method of MAPGIS in domestic software in building, have a good reference to the construction workers. This paper appeared in the process of building the processing opinion properly, the superior competent department improve construction standards and guidelines has certain reference function. To improve the domestic software MAPGIS has certain significance.
