Dear all,

I want to create a geotiff which has 2GB size at the end.

Further I used the option -co TILED=YES and the compression LZW.

Unfortunately a program breaks after opening the map.

Qgis need some time, but show the map.

What does Tiled=YES?

Should it "break" the file in 'handsome" segments to make it loadable in the pc ram similar to tiles in web services?

Make it sense to add a block size?


Can I change the file to another tif format and compress it with jpeg?


gdalinfo for a .vrt which I like to compress:


Coordinate System is:
PROJCRS["ETRS89 / UTM zone 32N",
    BASEGEOGCRS["ETRS89",
        DATUM["European Terrestrial Reference System 1989",
            ELLIPSOID["GRS 1980",6378137,298.257222101,
                LENGTHUNIT["metre",1]]],

.

.


Band 1 Block=128x128 Type=Byte, ColorInterp=Palette
  Color Table (RGB with 256 entries)
    0: 255,255,255,255
    1: 255,255,255,255
    2: 255,255,255,255
    3: 191,230,230,255
    4: 153,255,179,255
    5: 230,255,204,255
    6: 191,242,128,255

.

Thank you very much for your help!


Kind regard


Piet
