Anything else?

You can attach links to datasets.

Make sure your input DEMs are in floating point GeoTiff format.

I used the Copy Raster tool to export the raster as a 32-bit optimized GeoTIFF and it still isn't uploading correctly. Are there more settings I'm missing?

Can you zip the DEM. If it's small you can attach it to this ticket. If it's too big you might need to put it somewhere public on the internet and link to it here.

It looks like the file didn't upload correctly.
