遥感是一门收集远距离目标或景物信息的科学,对这些目标的研究离不开仪器。地质遥感开始于十九世纪,当时已发明了摄影技术。但是直到发明了飞机以后,遥感才得到广泛的应用。本世纪五十年代,随着图像雷达,热红外扫描仪及地球轨道卫星的出现,遥感具有了现代特征。然而对地质学家来说,遥感最重要的发展还足1972年以来三颗陆地卫星提供了地球表面大量的系统图像以及数字计算机应用于遥感资科的解释和分析。
Remote sensing is a science that collects long-range target or scenery information, and the research on these goals can not be separated from the instrument. Geological remote sensing began in the nineteenth century, when photographic techniques were invented. However, remote sensing was not widely used until the invention of the aircraft. In the 1950s, with the advent of image radar, thermal infrared scanners and earth orbiting satellites, remote sensing has the modern character. For geologists, however, the most significant development in remote sensing is that three terrestrial satellites have provided a large number of systematic images of the Earth’s surface since 1972 and the interpretation and analysis of digital computers used in remote sensing.
