ABSTRACTPhotoclinometry was used to analyze selected High Resolution Imaging Science Experiment (HiRISE) images of Transverse Aeolian Ridges (TARs) on Mars. Sixty Mars profiles have been assessed and a summary of their morphologic characteristics compiled. Measurements collected quantified the symmetry of the feature, the curvature of the crest, flank slopes, width, height and several comparative ratios. Results show that small TARs have physical characteristics generally similar to measurements obtained from lower resolution images of Mars. The HiRISE image data allow for much improved sampling along each feature; the improved resolution reveals relatively few features not seen in earlier studies, but is well suited for topographic sampling. Measured TAR profiles, when scaled by the width of the feature, can be compared to similarly scaled profiles for terrestrial dunes and megaripples. Published 2012.
