Hi, You asked help for understanding, so
Check the size of the original image: 309153 x 277451 Check how many bands: 1 Check how many bits per pixel for each band: 32 bits (makes 4 bytes) Multiply: 309153 x 277451 x 4 = number of bytes as uncompressed = 3.43099E+11 = 343 GB Compare with the 120 MB that you have and make a conclusion that the original is well compressed. -Jukka Rahkonen- -- Sent from: http://osgeo-org.1560.x6.nabble.com/GDAL-Dev-f3742093.html _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org https://lists.osgeo.org/mailman/listinfo/gdal-dev
