I am struggling to produce a terrian file with RAS Mapper.
I have a .tif file produced from a .asc raster elevation and when I tried to add a New Terrain Model as described in the documentation I get the following error:
Error creating Terrain: Input string was not in a correct format.
I have gone through all options related with the file paths and it seems to be something with the file itself, but what?
Among the many ways I have tried to produce it I am using GRASS.
The source of the raster data:
