Hi,I'm running gdal_translate against a VRT file: <VRTDataset rasterXSize="751" rasterYSize="801"> <GeoTransform>-20.05, 0.1, 0.0, 40.05, 0.0, -0.1</GeoTransform> <SRS> GEOGCS["WGS 84", DATUM["WGS_1984", SPHEROID["WGS 84",6378137,298.2572235630016, AUTHORITY["EPSG","7030"]], AUTHORITY["EPSG","6326"]], PRIMEM["Greenwich",0], UNIT["degree",0.0174532925199433], AUTHORITY["EPSG","4326"]] </SRS> <VRTRasterBand dataType="Float32" band="1" subClass="VRTRawRasterBand"><SourceFilename relativetoVRT="1">10day_precip.bin.1999121</SourceFilename><ImageOffset>0</ImageOffset> <PixelOffset>4</PixelOffset> <LineOffset>3004</LineOffset> <ByteOrder>MSB</ByteOrder> <NoDataValue>-999.0</NoDataValue> </VRTRasterBand> </VRTDataset>I just noticed that the resulting GeoTIFF is upside down. Is this a problem with my GeoTransform values? If so, what values would produce the image right side up?
Greg, I don't see any obvious problem with the geotransform values. Perhaps the image really is upside on disk. If so, you could flip it as it is read by changing your values to <ImageOffset>2403200</ImageOffset> <PixelOffset>4</PixelOffset> <LineOffset>-3004</LineOffset> Best regards, -- ---------------------------------------+-------------------------------------- I set the clouds in motion - turn up | Frank Warmerdam, [email protected] light and sound - activate the windows | http://pobox.com/~warmerdam and watch the world go round - Rush | Geospatial Programmer for Rent _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
