[mapserver-users] kml superoverlays

[Páll Péter Hunor]

Hi,

Thank you for this short discussion, now I think there is light at the 
end of the tunnel.
I tried solve my problem with MapServer 6.4.1 and GDAL 1.9, but that 
gdal version has write-only support for kml superoverlays.
First step is to change GDAL version in my project...
