Hello: I got DEM data from INEGI (Mexican Geographic Institute) and convert it to Geo Tiff.
gdal_translate -of GTiff -co "TILED=YES" MDE-n200000s190000e0970000o0990000.bil volcanes.tif gdaladdo -r average volcanes.tif 2 4 8 16 32 gdalinfo volcanes.tif Warning 1: TIFFReadDirectory:volcanes.tif: Wrong "StripByteCounts" field, ignoring and calculating from imagelength Driver: GTiff/GeoTIFF Files: volcanes.tif Size is 7200, 3600 Coordinate System is `' Origin = (-99.000000000000000,20.000000000000000) Pixel Size = (0.000277777777778,-0.000277777777778) Image Structure Metadata: INTERLEAVE=BAND Corner Coordinates: Upper Left ( -99.0000000, 20.0000000) Lower Left ( -99.0000000, 19.0000000) Upper Right ( -97.0000000, 20.0000000) Lower Right ( -97.0000000, 19.0000000) Center ( -98.0000000, 19.5000000) Band 1 Block=256x256 Type=UInt16, ColorInterp=Gray NoData Value=0 Overviews: 3600x1800, 1800x900, 900x450, 450x225, 225x113 Warning 1: TIFFReadDirectory:volcanes.tif: Wrong "StripByteCounts" field, ignoring and calculating from imagelength If I try to create the terrain database this way I get only a line osgdem -d volcanes.tif -l 8 -v 1.0 -o volcanes.ive so I have to give approximate pixel size with xx and yy and it apparently works. osgdem --xx 33 --yy 33 -d volcanes.tif -l 8 -v 1.0 -o volcanes.ive Is there not enough information in the geotiff file? or this is a bug?
