Abstract Based on spatial features, the authors identified preliminarily impact craters and linear tectonics by using Chang’E-1 satellite CCD data. First, many targets were segmented by using the edge detection method and then merged in order to reduce excessive and wrong segmentations. Second, the merging result was manually updated by using ArcGIS software so as to obtain geologically significant information. Finally, different identification rules were proposed for identification of impact craters and linear tectonics based on image spatial features. As a result, satisfactory results were obtained.
