GIS信息技术是目前矿产资源评价的手段,而GIS综合矿产资源评价实施则有赖于合理的相关矿产资源评价空间数据库建设,在GIS空间数据库建设中一项非常重要的内容是根据预测评价矿种及资料水平进行空间数据库的地学数据模型设计.
GIS information technology is the means of evaluation of mineral resources at present, and the implementation of GIS comprehensive mineral resources assessment relies on the construction of reasonable spatial database of mineral resources evaluation. In the construction of GIS spatial database, a very important content is based on the prediction and evaluation of mineral resources and Data level Geospatial data model design of spatial database.
