HJ-1A Hyper-spectral Remote Sensing Alteration Information Extraction and Analysis

Abstract

Compared with the traditional geological survey and prospecting mapping, hyper-spectral geological mapping costs low, low consumption, therefore, the selection of hyper-spectral remote sensing data is the potential prospects of innovative traditional survey methods. The study field of Xiemisitai Mountain east section of west Junggar Basin northwest is main objection. Using geological data and hyper-spectral remote sensing alteration information extraction technology researching as a starting point, through field measurements of the spectral characteristics of alteration minerals analysis, combined with China's environmental mitigation satellite (hereinafter referred to as the HJ-1-A) HSI image to extract the iron ore alteration of the study area.
