[mapserver-users] question on layer projection and WMS

[Bart van den Eijnden (OSGIS)]

Hi Reinoud,

I do have a PROJECTION block at the MAP object, as well as WMS_SRS METADATA
in my LAYERs. So I am quite sure the warning is about the missing LAYER
PROJECTION block.

But as you said, this should not be needed anymore, and the warning should
be updated to reflect this.

Best regards,
Bart
