In this presentation we report high resolution estimates of surface roughness/slopes corresponding to various types of latitude-dependent morphology with intention to provide data for future rover exploration. The basic method is photoclinometry applied to HiRISE data to estimate m-scale roughness. [2] have already conducted m-scale topographic mapping for the survey of Phoenix landing site. Our aim is to construct basic data base for roughness/slope statistics of m-scale of typical surface types. Since the coverage of HiRISE image is limited we measure roughness by CTX, MOC and THEMIS-VIS data at coarser length scales. We combine fine scale (m-length scale) roughness spectrum and coarse scale (10-20 m) spectrum to a consistent spectrum. In combination to conventional photoclinometry approach we use thermal infrared images to estimate roughness based on the analysis of [1].
