基于GIS的矿区三维重建

Three-dimensional rebuilding of a mining area based on GIS

文章探讨了以三维GIS为基础的某多金属矿区的三维重建过程及其实现。三维重建的过程可以概括为二维图形编辑、三维图形编辑和建立属性数据库。三维重建后,可以在三维模型的基础上对矿区进行相应的空间分析,如空间查询、断面分析等。同时提出了实际应用中存在的一些问题,并对该技术的发展前景作出了展望。

The three-dimensional rebuilding process of a certain multi-metal mining area and its realization based on the three-dimensional geographic information system(GIS) are discussed. The three-dimensional rebuilding process contains two-dimensional graphic editing,three-dimensional graphic editing, and attribute database establishment. The spatial analysis of the mining area can be carried out on the basis of the three-dimensional model,for example,spatial query, section analysis and so on. Some problems in practical application are also discussed. It is considered that the three-dimensional GIS technology will be applied widely in the geologic field for its superiority.
