This image shows the relative heights and depths of a region in the southern hemisphere of Mars showing the Sirenum Fossae fracture system.
As indicated in the key at top right, whites and browns/reds represent the highest terrain, while blue/purple is the lowest (values are marked on the scale).
The colour-coded topographic view is based on a digital terrain model of the region, from which the topography of the landscape can be derived.
The region was imaged on 5 March 2017 during Mars Express orbit 16688. The ground resolution is approximately 14 m/pixel and the images are centred at 28°S / 215°E. North is to the right.
