J-S, Thanks for the files. I was able to use them to make it work. The problem was that the original TIFF had go spatial information. So, I assigned it the proper SRS with:
gdal_translate -a_srs WGS84 32V.tif 32V.wgs84.tif Then I was able to reproject it into UTM: gdalwarp -t_srs "+proj=utm +zone=32 +datum=WGS84 +units=m" 32V.wgs84.tif 32V.utm.tif And finally a test run through osgdem: osgdem --terrain -d 32V.utm.tif -o out.osg And that yields a good UTM dataset.
