卫星遥感技术在矿产勘查设计中的应用

Application of satellite remote sensing technology in geological exploration design

在前期基础工作开展较少的情况下,通过对卫星遥感技术成果的分析和集成,可生成反映勘查区地形地貌特征的图件,并能对勘探工程的规划和布置提供空间数据支持。本文从卫星遥感技术数字DEM产品的获取、不同坐标系的转换、栅格文件裁剪、地形图生成以及卫星影像Key参数和密钥的申请、ArcGis在线调用高清卫星影像等方面进行阐述。卫星遥感技术不仅在快速获取地貌特征方面取得成功,同时在不同颜色岩体的识别、矿产资源利用监测、勘查决策和规划等领域不断获得更广泛的应用。

Under the condition that the initial basic work is less carried out,through the analysis and integra⁃tion of satellite remote sensing technology achievements,maps reflecting the topography and geomorphology characteristics of the exploration area can be generated,and spatial data can be used to support the planning and layout of exploration engineering.This paper expounds the acquisition of digital DEM products in satellite remote sensing technology,transformation of different coordinate systems,raster file clipping,topographic map genera⁃tion,application of key parameters and keys of satellite image,and online access of high-definition satellite image by ArcGIS.Satellite remote sensing technology has been widely used in the fields of rapid acquisition of geomorphic features,identification of rock masses with different colors,monitoring of mineral resources utiliza⁃tion,decision-making and planning of exploration.
