自1972年美国发射“陆地卫星”1号(过去称“地球资源卫星”)以来,卫星遥感技术在矿产勘查及其他工程应用上已逐渐为人们所接受.卫星遥感的优越性是获取地质信息面广、速度快和花费少,因此受到人们日益重视.但是,早先的卫星只装有一种多波段扫描器(MSS),仅能获取四种遥感影象,即红、绿和两种近红外光谱.许多地质学家惋惜这种遥感缺乏用于指示矿物和土 Since the United States launched Land Satellite 1 (formerly known as Earth Resources Satellite) in 1972, the satellite remote sensing technology has been gradually accepted in mineral exploration and other engineering applications.The superiority of satellite remote sensing is that it can obtain geological information surface However, the earlier satellites were equipped with only one multi-band scanner (MSS) and were able to capture only four remote sensing images, namely, red, green and two near-infrared spectra Many geologists regret this lack of remote sensing to indicate minerals and soil
