HiRISE digital terrain models (DTMs) and anaglyph images over the Opportunity field site
Digital Terrain Models (DTMs) are high-resolution topographic data computed from stereo pairs of HiRISE images. For Opportunity, there are only two DTMs, outlined in blue on this map. There are also two sets of stereo pairs that have been converted into anaglyphs for 3D viewing, outlined in green on this map. Finally, there is a stereo pair taken over Santa Maria Crater that has not yet been converted to an anaglyph, but could be, marked in purple on this map. Opportunity's traverse is marked in yellow.
