As of ArcGIS Pro 3.2, this functionality is now available through the Filter Coordinate Systems button next to the Search bar in the Coordinate Systems tab of the Map Properties dialog. Once you click on that button, you can go to the bottom of the resulting dialog, toggle "Projection property", and choose the property you wish to filter by. ... View more

I don't know of any alternatives; I've always converted rasters to arrays. I find it helpful to use something like this pattern: inputRaster = arcpy.Raster(inputPath) cX = inputRaster.meanCellWidth cY = inputRaster.meanCellHeight crs=inputRaster.spatialReference anchorX = inputRaster.extent.XMin anchorY = inputRaster.extent.YMin corner = arcpy.Point(anchorX, anchorY) inputArray = arcpy.RasterToNumPyArray(inputRaster) outputArray = DoAllYourNumpyStuff(inputArray) outputRaster = arcpy.NumPyArrayToRaster(outputArray,corner,cX,cY) arcpy.DefineProjection_managment(outputRaster,crs) ...

Hello, It looks like the issue may be that np.cos, a NumPy function, is being called on an ArcPy Raster object. My understanding is that ArcPy rasters need to be converted to Numpy arrays with arcpy.RasterToNumPyArray() before this will work. You can convert back with arcpy.NumPyArrayToRaster(). Hope this helps, -Charles ... View more

Hello Simon, The help document should say that GCS WGS 1984 is the only CS option for global scenes. It looks like this is an error in our 2.3 help, but this will be fixed in the update to 2.4. As for support for other planets, extraterrestrial datums are supported for maps and local scenes, but not for global scenes. We are investigating the potential support of other planets in global scenes in a future release. -Charles ... View more

Hello, "CM" probably refers to "central meridian". The central meridian of UTM 30N is 3°W, so it seems a good bet that WGS 84 UTM 30N is the correct coordinate system. You should be able to verify this by doing the following: Use "Define Projection" to assign WGS 84 UTM 30N to a copy of your data. Load the result in a map and check that it agrees with either a base map or with data for which you know the correct coordinate system. -Charles ... View more
