地球资源技术卫星(ERTS)多光谱扫描仪(MSS)所得到的计算机兼容磁带(CCT)记录着丰富的地表信息,对其进行数字图象处理,可以获得多种极为有用的资料,因此引起人们的普遍重视。本文拟通过笔者的理解,结合上机进行西北某些地区的图象处理实践,对其在解决构造问题中的应用方法和效果进行初步探讨。 (一) 陆地卫星CCT的特点及其在西北地区的适用性由于多光谱扫描仪的地面分辨率(79m)和波段数(MSS4、5、6、7)有限,再加上我国所得到的基本都是单时相图象,以及所记录光谱的表面性和综合性的特点,致使陆地卫星
Computer-compatible tapes (CCTs) obtained with the Earth Resources Satellite Technology (ERTS) Multispectral Scanner (MSS) record abundant surface information and are digitally imaged to provide a wide range of extremely useful information that has caused people The general attention. This article intends to carry on the image processing practice in certain areas of northwestern China through the understanding of the author, and discusses the application methods and effects in solving the problem of structure. (1) Features of Landsat CCT and Its Applicability in Northwest China Due to the limited resolution of the multispectral scanner (79m) and the number of bands (MSS4,5,6,7), coupled with the basic Are both single-phase images, as well as the superficial and comprehensive characteristics of the recorded spectrum, resulting in the loss of land satellites
