“3S”技术在资源地质调查中的应用

Application of “3S”Technique in Geological Prospecting of Resources

利用遥感(RS)、全球定位系统(GPS)、地理信息系统(GIS)等高新技术的有机配合可以快速高效地完成环境条件恶劣地区的资源地质调查工作。以宁夏碱沟山地区煤田地质调查为例 ,介绍了“3S”技术的应用情况。即应用法国SPOT卫星图像对地质、地貌等要素进行综合解译、对比和分析 ;应用全球定位系统对地质、地形地貌等要素进行野外控点 ;应用地理信息系统对调查成果进行综合分析、编辑和制图。总结了应用“3S”技术进行资源调查的工作方法和程序。“3S”技术进行资源地质调查具有快速高效、低成本的优势 ,值得在今后的国土资源调查中推广和应用。

Integration of remote sensing、globe positioning system and geographical information system can predict geology and resources effectively in poor natural environment.The authors introduce the applications of “3S”technology in 1∶25000 geologic prospecting taking coal resources in Ningxia Hui autonomous region as example. Including application of France spot satellite image in geologic and geomorphological interpretation、globe positioning system in field location and geographic information system in synthetic analysis and mapping, and summarize a series of new applications on “3S”technology in geologic and resources prospecting.
