Martian valley networks bear some resemblance to terrestrial drainage systems, but their precise origin remains an active research topic. A limited number of valley networks have been manually mapped from images, but the vast majority remains unmapped because standard drainage mapping algorithms are inapplicable to valleys that are poorly organized and lack(More)
A novel automated channel mapping algorithm is developed and applied to map valley networks in variety of sites on Mars. The algorithm uses digital topography data from which topographic planar curvature is calculated and a series of steps is implemented to convert curvature map into a map of channels. Results in eight test sites are compared to accurate(More)
