Thread created for posting MSL route maps and map updates.
Comments / suggestions adding value to the route maps are allowed, but discussions regarding the route itself and "future" paths are not. Use the currently active thread for the latter. Eduardo Tesheiner Moderator ----- Here's an updated map of activities near the landing site and the start of a map of the route to Glenelg. I may get one more step added to this before I have to take a break Aug. 31 to Sept 16, and I will resume it after that. Details will be revised as necessary as we go.

Michael,
I love your map... but there's something seriously wrong with it. First the rover route is way off. Here is a version with Tesheiner's GE overlay superimposed. Second, I can't reconcile the contours with surface features in some areas. I suspect a difference in map projection or registration between base image and DEM. Can you take another look?

Thanks Phil, I think there is a registration issue. When I recently tried to mosaic the HiRISE DEMs (derived from stereo-pair imagery) in Gale Crater, there was some noticeable mis-registrations where the DEM boundaries met, so I was concerned about the georeferencing of this data. I also need to familiarize myself with Martian geoids (areoids?) and coordinate systems.
I'll study this problem and consult the HiRISE documentation some more. I can "fix" the registration by applying a delta x- and y- shift, but that's a very last resort. I looked at the base image layer versus DEM and they do seem to align well. The base image is PSP_010573_1755_RED.jp2 and the DEM is DTEEC_010573_1755_010639_1755_U01.IMG Do you know if the post-landing imagery is orthorectified? If so, can someone point me to it? I can use that instead. Tesheiner, thanks for the KML, I'll make a new map once I sort out the map alignment issue. A number of interesting map products can be derived from the DEMs: slope maps, gradient maps, aspect maps, viewshed maps, etc. I'll work on those soon after the map registration issues are resolved. I've got to get back to work now, I'll work on this some more tonight and over the weekend. |
