Hi All,
I'm new to translating rasters and i'm looking at doing a simple translation from GeoTiff to ASCII grid data. The Geotiff is a simple single band DSM with REAL32 datatype. I've created a workbench that has the Geotiff as the reader and ASCII as the writer. I am also clipping the original Geotiff, so I've got a clipper in there as well. However, when I run this I get an error 'ESRIASCIIGRID writer: Failed to obtain raster from feature. Only features with raster geometry are expected'. I was kind of expecting something along these lines, because I suspected you need to extract the height info from the band before converting it to ASCII. How do you do this please?
Thanks
Dave
