Engineering Geology Application Technology System of Airborne Hyperspectral Remote Sensing and Its Exploration Demonstration
摘要
Abstract
Airborne hyperspectral remote sensing has the characteristics of both high spatial and high spectral resolution,and has important value in geological and mineral exploration application.This article conducts research on remote sensing geological applications based on the CASI/SASI airborne hyperspectral data.A complete technical workflow for engineering geological application of airborne hyperspectral remote sensing is established,including hyperspectral data acquisition,preprocessing,mineral mapping,interpretation of lithology and fault structure,construction of ore exploration models,delineation of favorable ore exploration sections,and field verification and optimization.New methods for the acquisition of high quality airborne hyperspectral data,the engineering mineral mapping,and for the fine identification of lithology are proposed.9 types of airborne hyperspectral products was conducted,and a complete geological survey technology system using airborne hyperspectral remote sensing has been constructed.This article takes Liuyuan area in Gansu Province as a typical area to carried out an airborne hyperspectral-geological exploration demonstration.As a result,11 favorable sections for hyperspectral exploration were delineated.After the field investigation,several surface mineralization clues were newly discovered,such as the Nanjintannan gold anomaly,the Luotuobozigou gold anomaly.As shown in above,the airborne hyperspectral remote sensing technology has achieve fine application in geology.关键词
