I created a NetCDF file and then added it as a multidimensional voxel layer to ArcGIS Pro. I then got this warning:

Voxel layer can only be drawn in local scenes with the same coordinate system as the voxel layer. Change the scene to a local scene and the coordinate system of the scene to match the voxel layer.

Looking at the scene's Map Properties > Coordinate Systems, I found that my voxel layer used the WGS 1984 coordinate system while the World Topographic Map and WorldElevation3D/Terrain3D layers used the WGS 1984 Web Mercator (auxiliary sphere) coordinate system.

I found this FAQ that suggets using a projection file to override the coordinate system of the NetCDF file used for the voxel layer. I did it successfully, and got my voxel layer, AIRS_Voxel, to use the WGS 1984 Web Mercator (auxiliary sphere) coordinate system.

However, I'm still getting the same warning about the coordinate systems not matching. I've also tried changing the Z coordinate system to both None and WGS 1984, to no effect. I've also restarted ArcGIS Pro, to no effect.

Here's the spatial reference for my voxel layer, in case it helps:

What should I do?

EDIT: The warning about coordinate systems not matching is no longer showing. However, the voxel layer still won't display.

  • Voxel layers can only display regularly gridded data. There is a note in the voxel FAQ. Could this be the cause of your display problem? Commented Aug 4, 2023 at 22:31
  • @MarkBryant This indeed turned out to be the issue, along with needing my region to be at least 33x33 degrees.

I have managed to find a solution to my issue with the help of Esri's support (Andrew--Johnson of Esri). (our discussion on this matter is available here).

There were two issues that led to the voxel layer not displaying:

  • The z-dimension was not regularly gridded
  • The geographic region of my data was small
