[mapserver-users] How to tile a large TIF image?

[Stefan Schwarzer]

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
