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?

    The "No transform is available between EPSG:4326 - WGS 84 and Unknown CRS" seem to imply that some of your data are recognized as having a CRS from earth, could you provide more information on what you did and how you did it ? – J.R Jul 25 '20 at 22:05
  • i just added the raster layer in qgis while setting up the CRS i chose the mars one but it gave me the mestioned error – user7587298 Jul 26 '20 at 19:47

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.
