heal.abstract	A methodology was designed that delineates Valles Marineris chasma, an elongated steep-sided depression, from Mars MOLA DEM data. The DEM-to-Mount transformation was implemented allowing the segmentation of chasma sides and the elevated features lying on the basin floor Iterative connected components labelling followed by region filtering on the basis of size thresholds, allowed the filtering of craters developed on the surrounding plateau, and resulted in the refinement of Valles Marineris to a single compound object that was described parametrically. Finally it was segmented to facets with the same aspect pointing direction (aspect regions). Each region was parametrically described on the basis of its mean elevation and gradient, and mapped.	en
