Setting up CRS for Mars images taken by a satellite

Geographic Information Systems Asked by user7587298 on September 2, 2021

I have a PDS image of the Valles Marineris taken by the Mars Orbiter Missions (MOM) Mars Colour Camera (MCC). I have to generate a depth map and I am in the process of creating a 3D model.
In the provided metadata I have latitude and longitudes of 9 reticle points on the given image.
When I try to set the provided CRS I am prompted with the following error:

No transform is available between EPSG:4326 – WGS 84 and Unknown CRS: GEOGCRS["unknown",DATUM["unknown",ELLIPSOID["unkno….
proj_create_operations: Source and target ellipsoid do not belong to the same >celestial body

The CRS that I tried were the following:

  • Mars_2000_(Sphere) ESRI:104971
  • GCS_Mars_1979 ESRI:104904.

Are there any suggestions for setting up a CRS or any other way to generate a depth map?

One Answer

Since you are using a non Earth projection for the layer, must check on the No projection (or unknown/non-Earth) option for the project map, in Project Properties, CRS tab.

And do not change the unknown CRS of the layer.
