Abstract

The exploration of the Moon has become an important goal for several countries in order to set up foundations for future exploration of mineral resources. In the framework of the cooperation project “Moon Mapping” between Italy and P.R. China, a working group has been established to study landslides inside impact craters. So far, WAC (Wide Angle Camera) images and DEM (Digital Elevation Model) maps from LROC (NASA) at 100 m/pixel have been used to visually recognize some landslides in impact craters. Further steps include: (i) the classification of impact craters; (ii) the identification for each crater type of a theoretical shape; (iii) the automatic identification of the landslide through the analysis of deviations from the theoretical shape; (iv) the measurement of the landslide deposit volume; (v) the analysis of relationships between landslides and characteristics of the hosting craters and of the surrounding terrain (topographic slope, geology, etc); (vi) the comparison of multispectral data with available spectral libraries to map geological features on the Moon surfaces.
