[mapserver-users] Tiled PNG doesn't work for WCS (and WMS)

[Steven M. Ottens]

Hi all,

Thanks to Frank the problem was drilled down to the way the relative  
paths where defined in the index shapefile. Using absolute paths in  
gdaltindex did the trick.

Unfortunately Geoserver 1.7.6 is faster on the same machine, with the  
same dataset as Mapserver 5.0.2 :(

Thanks for all the help
