Download: Google Earth 5 w/Mars
An early overview is available here. This is exactly what I've been waiting for ever since Google Earth came out five years ago. And HiRISE integration is amazing. |

I hope Google includes the MOC,CTX and HIRISE images in the next release!
That way i can resume my search for volcanoes on the red planet ! Good thing theres a lot of user discoveries, overlays, databases, and info at Google Earth Community! -------------------- "Thats no moon... IT'S A TRAP!"

Does anyone know exactly how Googe Mars does obtain their Digital Terrain Models (DTM) used to render those views ?
It was my understanding that they use the MOLA base map (200-meter-ish post spacing) plus HRSC (Mars Express) DEMs (~50 m resolution) where available and only then draping CTX/HiRISE images etc. over them. HOWEVER: The impression from views like that of the "half crater" and "landslide-alley" posted by Stu above is that the actual terrain models must be considerably more accurate than MOLA alone. But yet there does not seem any other altimetry data of that region (i.e. HRSC or HiRISE DTMs) The only related data is CTX imagery but that is 2D-only, i.e. can be draped over the terrain) So are we seeing still officially unreleased HRSC DTM data, or am I missing some other sources ? A related question: is there a way to view/save the data in Google Mars as a height map, i.e. similar to what is displayed in the "google maps" like window at the bottom of each HiRISE observation page (i.e. http://hirise.lpl.arizona.edu/ESP_016354_1745 ? |
