Hello all I'm using gdal utilities to georeference some tiff files.
I'm inserting the gcp using: gdal_translate -gcp .... original.tif original_gcp.tif Then I use gdalwarp to gereference the images: gdalwarp -t_srs EPSG:32633 original_gcp.tif original_warp.tif The resulting Geotiff is correctly georeferenced and the size is approximately the same of the original The problem arise if I insert the options -co COMPRESS=LZW at the warping. The process end successfully but the resulting geotiff is 6 times the size of the original one! I've tried to use: gdal_translate -of GTIFF -co COMPRESS=LZW original_warp.tif original_warp_lzw.tif and it produces a geotiff smaller than the original. Am I doing something incorrect? thank you in advance Stefano --------------------------------------------------- 41.95581N 12.52854E http://www.linkedin.com/in/stefanoiacovella http://twitter.com/#!/Iacovellas _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
