Miranda - depth estimation from a single image / test - false color

Visual interpretation of relief on Miranda based on depth estimation from a single image

 

Zoedepth was not trained for DTM - the 3D image may contain errors, since it's not based on a DTM but on an AI model that hasn't been trained on planets.

 

Process on 2d image : false color, not RGB

Not based on a DTM, but a visual interpretation of the surface

Citation of NASA photojournal about the original image in black and white :

"This image of Miranda, obtained by Voyager 2 on approach, shows an unusual 'chevron' figure and regions of distinctly differing terrain on the Uranian moon. Voyager was 42,000 kilometers (26,000 miles) away when its narrow-angle camera acquired this clear-filter view. Grooved areas baring light and dark bands, distinct from other areas of mottled terrain, are visible at this resolution of about 600 meters (2,000 feet). The bright V-shaped feature in the grooved areas is the 'chevron' observed in earlier, lower-resolution images. Cutting across the bands are sinuous scarps, probably faults. Superimposed on both types of terrain are many bowl-shaped impact craters less than 5 km (3 mi) wide. The entire picture spans an area about 220 km (140 mi) across. The Voyager project is managed for NASA by the Jet Propulsion Laboratory".
