Thanks for the info.
Did it like this:
Library/Frameworks/GDAL.framework/Versions/1.5/Programs/gdal_translate
-outsize 10'' 10'' -co TILED=YES gebco/bathymetry.tif gebco/
bathymetry_tiled.tif
But get the message: "Segmentation fault"
Anything that I did wrong? Or should do differently?
Thanks for a hint,
Stef
