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 attempt has been made at geological interpretation of the data of size able coverage areas obtained by Landsat by means of digital image processing and model identification.The method of non-supervise classification proposed in this study is essentially an improved variety of cluster algorithm.It is not only characterized by convenience rapidity and easier adaptation to minicomputer from the viewpoint of formation,disintegration and integration of initial condensation points,but also enhances the interactive function and makes the result of classification more satisfactory.The output result of classification displays the special distribution of soil types.Since the distribution of some soils corresponds to relative subsurface structures,a feasible approach is provided for geological interpretation of covered areas.
