So I am having some issues getting my USGS DEM to display in 3d in ArcScene. I downloaded my DEM (.jpg) and brought it into ArcScene. I clicked properties and base heights and floating on a custom surface, and then after accepting, the DEM is still completely flat.
What am I doing wrong?
I thought I had already put it into a projected coordinate system.
What coordinate system is it in when I download it from USGS?
How would I change it correctly?
What I am trying to do ultimately is use the 3d elevations for a flood simulation.
