The Aeolian processes are key elements to understand the surfaces of celestial bodies with atmosphere. This paper performs an analysis of aeolian activity on Herschel crater, from two dune fields in different topographical settings. At East field, between small simple craters, and at West, the dune field is located inside a large impact crater near to uplifted central peak. As source of data will be employed high resolution images (spatial resolution 0,25 m/pixel) and digital terrain models (DTM), with 1m / pixel spatial resolution, generated by HiRISE sensor of orbital probe Mars Reconnaissance Orbiter (MRO).Were measured horizontal parameters (Area,Azimuth length, width , and length/width ratio) and vertical parameters (height of crest (Hc), height of slipface (Hs),slipface slope, curvature) of 10 dunes in each field.
