一、简要的回顾现代地质遥感研究的广泛开展开始于第一颗陆地卫星(Landsat-1,原名ERTS-1)的使用(1972年7月)。这种资源卫星对地球的绝大部分地面作周期性的重复覆盖的摄象,提供了全世界范围的高质量的多波谱图象资科,揭示了丰富的地质信息,特别是大型及隐伏的线性构造。随后又陆续发射了陆地卫星2号(1975年1月)及3号(1978年3月),互相 I. A Brief Review The extensive development of modern geospatial remote sensing research began with the use of the first Landsat-1 (formerly ERTS-1) (July 1972). The satellite imagery, which periodically and repeatedly covers most of Earth’s surface, provides a worldwide resource of high-quality multi-spectral images revealing a wealth of geological information, particularly large and latent Linear structure. Subsequently, Landsat 2 (January 1975) and No.3 (March 1978)
