[mapserver-users] Trouble with mode=tile

[Dave Rafkind]

Hi, thanks for your reply. Results follow:

I can't remove the PROJECTION block, otherwise I get this error from 
mapserver:
msTileSetProjectionst(): WMS server error. Cannot set new SRS on a map 
that doesn't have any projection set. Please make sure your mapfile has 
a PROJECTION defined at the top level.

QGis thinks this is the spatial information for my test shapefile, this 
is 4326 (basically unprojected), right?
+proj=longlat +ellps=WGS84 +datum=WGS84 +no_defs

If I have the PROJECTION block in the mapfile, I can indeed see tiles of 
some kind, but it looks like each tile overlaps in its spatial extent.

See attached for "wrong" results..I changed some of the colors so it 
would be more obvious.
