Application of satellite remote sensing technology in geological exploration design
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.
