Extraction and Analysis of Mineral Information of Pulang Copper Ore Based on Hyperion Data
In order to overcome the problems of high altitude,poor traffic conditions and limited traditional exploration methods in Pulang ore district,hyperspectral remote sensing technology is used to extract rock and ore information more conveniently and accurately.Using Hyperion data,the pure pixel is extracted as the end element by the minimum noise separation transform and the pure pixel index method,and the end element spectrum is obtained by N-dimensional visualization analysis.Then,spectral Angle mapping is used to extract altered minerals in the study area,and combined with known geological data analysis,to verify the feasibility of this method.The results show that hyperspectral re-mote sensing can accurately identify the types of altered minerals and display the distribution range.At the same time,the results show that it can map the minerals and improve the availability of alteration information,which is of great significance for remote sensing extraction of alter-ation information in the Pulang copper ore district.
