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
