I was trying to create a new RAS classification layer using USGS NLCD 2016 dataset (.img format) in HEC-RAS 6.1 and 6.0 versions. Both gave me an error message as “Unknown Error: Bad Tiff Format”. Then I tried with v 5.0.7 and it worked. Anyone had the same issue with v 6.0/ 6.1? Not sure if that is a bug in the new version but any suggestions would be highly appreciated.
No, I have not had any issues with this, however you can create it in 5.0.7 and then use the “add existing land use RAS layer” and load it in the newer version
Hello,
I too am having this issue. Is there any pre-processing that I can do to the NLCD data for 6.0.1 to recognize this format? Or should I step back to 5.0.7?
