Hi I have scanned in maps, that needs to be georeferenced. I usually did the georeferencing in ArcMap. I would like to move a away from propriety software to do this.
I used gdal_translate to georeference the supplied tif file. The result is "upside down". So i went back ArcMap, load the original un-georeferenced tif file and it is displayed correctly. I then loaded the gdal_translate produced georeferenced file, and it display "upside down". What am i missing? When generating a preview of the gdal_translated georeferenced tiff file in the windows explorer it displays correctly. Maybe this suggest that some tag or flag in the gdal_translate produced file is not set? I get the same result with the FWTools 1.3.5(very old) and FWTools 2.4.7 Here is the gdal_translate command i used. gdal_translate -a_ullr 28.4696526275608 4.96918660287081 30.029965644484 6.29703349282297 E:\Gis\wt250cd_sb35-8_0528_kalemie_2005_ed1.tif E:\Gis \wt250cd_sb35-8_0528_kalemie_2005_referenced.tif Here is the gdalinfo information on the original tif file. gdalinfo.exe e:\Gis\wt250cd_sb35-8_0528_kalemie_2005_ed1.tif Driver: GTiff/GeoTIFF Files: e:\Gis\wt250cd_sb35-8_0528_kalemie_2005_ed1.tif Size is 8175, 6938 Coordinate System is `' Metadata: TIFFTAG_SOFTWARE=Adobe Photoshop CS3 Windows TIFFTAG_DATETIME=2008:06:24 10:21:23 TIFFTAG_XRESOLUTION=300 TIFFTAG_YRESOLUTION=300 TIFFTAG_RESOLUTIONUNIT=2 (pixels/inch) Image Structure Metadata: COMPRESSION=LZW INTERLEAVE=PIXEL Corner Coordinates: Upper Left ( 0.0, 0.0) Lower Left ( 0.0, 6938.0) Upper Right ( 8175.0, 0.0) Lower Right ( 8175.0, 6938.0) Center ( 4087.5, 3469.0) Band 1 Block=8175x10 Type=Byte, ColorInterp=Red Band 2 Block=8175x10 Type=Byte, ColorInterp=Green Band 3 Block=8175x10 Type=Byte, ColorInterp=Blue Best Regards Theuns Heydenrych _______________________________________________ gdal-dev mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/gdal-dev
