[mapserver-users] Mapserver tile generation - google maps

[Wim Vanbelle]

For reference sake:

The issue is also present when using Bing maps as overlay.
I also recompiled mapserver against agg 2.5 and gd-2.0.36RC1, but no change
unfortunately.

As stated in my previous mail, I may have to look for alternatives as the
tilecache will probably not be an option for us.

Would it be possible to circumvent this problem by using WMS?
