基于三维GIS的济南市矿山地质环境航测调查管理系统设计与实现

随着矿产资源大规模的开发利用,加剧了地质环境的不断恶化,矿山地质环境保护迫在眉睫,传统的矿山地质环境调查技术已经显得乏力。该文以济南市矿山地质环境航测调查为例,提出了基于三维GIS的矿山地质环境调查方法,利用三维GIS的高性能空间数据引擎、直观的可视化技术和强大的空间分析能力,整合济南市高分辨率的航空影像数据、DEM数据、倾斜摄影数据和历年的监测图斑数据,重建航测调查区真实的三维地貌。结合矿山开采信息,进行航测调查区矿山开采现状图斑的提取及拓扑处理,查明矿山地质环境破坏、地质灾害隐患情况,有效监测矿山地质环境,加强重点矿山开采区的监测与管理,推动济南市矿山地质环境保护工作。

Design and Implementation of Photogrammetry Investigation System of Mine Environment Based on 3D GIS in Jinan City

Accompanying with large scale development and utilization of mineral resources, geological environment has been becoming more and more worse. Geological environmental protection of mines is very urgent. But the traditional technology for surveying geological environment of mines has become weak. In this paper, setting geological survey of mines in Jinan city as an example, the method of geological environment investigation based on 3D GIS has been put forward. By using highperformance spatial data engine of 3D GIS technology, integrating intuitive visualization technology and powerful spatial analysis ability, the aerial image data, the DEM data, the tilted photographic data and the monitoring plots data over the years, real 3D geomorphology of the aerial survey area has been reconstructed. Combining with mining information, the extraction and topology processing of present condition of mineral exploration have been carried out, It will identify the condition of geological environment damage and geological hazards effectively, monitor geological environment of mines, strengthen the monitoring and management of key mining areas, and promote geological environment protection in Jinan city.
