I have recently freaked out a little bit about Martian maps of all sorts. And finally I was astonished with those highly detailed beauties that I list below. Nonetheless. some of them have huge inconsistencies (crater names) easily noticed when we compare the surroundings of Gusev crater. Enjoy:

Great, I'm glad you were able to make some use of it. I'm a GIS neophyte so appreciate you posting the details.
In terms of other potential resources - this SPICE topocentric kernel was made pre-landing, but other than exact coords of actual landing has useful detail: https://naif.jpl.nasa.gov/pub/naif/MARS2020...z_iau2000_v4.tf (it in turn leads to many rabbit holes, but I think the upshot is that "IAU" + "east-positive longitude" seems to indicate planet'ocentric). The above kernel provides the local definition that connects to the rover kernel, which fully defines all the other transformations. Note that the one in the main folder doesn't seem to be quite as complete as this one, which has more instruments: https://naif.jpl.nasa.gov/pub/naif/MARS2020...ee/m2020_v03.tf So far as I know (which isn't that far) PLACES is internal to JPL. But the data does get published with the periodic PDS releases. I think the .geojson is a great asset that gets most of what we'd want from there in terms of near-real-time location data. |
