I will like to project my DEM from GCS_GDA_1994 into UTM but when I select Projections and Transformations> Raster -> Project, I can't find the file that represents my DEM. I am using ArcGIS 10.5.
Can anyone help please? Thank you.
When you can't find the file that represents your DEM, are you talking about the spatial reference needed for the DEM or the DEM itself?
If you are referring to the DEM itself, if you have your DEM in your table of contents, can you right click on it and open the properties pane. Under the source tab, you can find the path to the file.
