[mapserver-users] Rewarping/Reprojection with GDAL and -wo EXTRA_SOURCE parameter

[Heiko Schröter]

Oh Andreas, blind me.
Copied it into the POSTGIS layer but not the LINE Layer.
Sorry for that.
It works now as described, panning and zooming is ok.

Btw, where to send the bugreport ?

Thanks and sorry for the additional noise.

Regards
Heiko
