1/9 arc second IMG files from USGS?

by Kevin Daye

Feb 2, 2018

I'm using Elk 2.2.2 and was able to find a 1/9 arc second DEM file (in IMG format) on the USGS National Map of the area of my interest. However, When I try to import the file I always get a domain error no matter what my Lat/Long values are.

Can Elk use these files?

    Hi Kevin, did you ever find a solution to this? I'm able to get the 1/3 arc second data to load, but not the 1/9 data for the same region. I notice that the file structures of the two ZIPs are different, which might be the root of the problem. I can dig into it later, but wondered if anyone else had found a workaround first.

      I have the same issue with a geotiff from open topography on another area. I always got issues wit the exact lat and long.Any suggestion anyone?
