Abstract:

Craters are one of the major features on lunar surface, it is important to study their characteristics. The craters identified from the  first image Chang’e-1 can be classified into 4 types, such as the normal, central mound, flat-bottomed and concentric craters. The morphological characteristics of different craters are described. Making using of remote sensing professional software, the diameter information and spatial distribution of the craters were extracted with Bessel geodetic algorithm. The results showed that craters’ diameter are mainly concentrated between 300 and 700 meters.Their spatial distribution is inhomogeneous, and its densest degree rises with diameter decreasing.
