遥感技术地质应用中的一个重要环节是图象的解译。众所周知,陆地卫星的多光谱扫描(MSS)影象通常仅反映不同光谱通道的地表景观,地质解译就是将地下地质状况与地表景观二者间建立正确的联系。在良好露头区,卫片的目视解译比较容易;在大面积覆盖区,则目视解译相当困难。
An important link in the geological application of remote sensing technology is the interpretation of images. It is well-known that multispectral scanning (MSS) images of terrestrial satellites usually only reflect the landscape of different spectral channels. Geological interpretation is the correct connection between the underground geological conditions and the surface landscape. In a good outcrop area, the visual interpretation of the patch is easier; in a large area of coverage, the visual interpretation is rather difficult.
