[mapserver-users] google tiles

[Roger André]

Fascinating, thanks for sending the link!  Since you state that you only get
blank images when you try it out, perhaps it is a projection mis-match? It
appears that your mapfile extents are defined in meters, which would match
spherical mercator, but your layer is in EPSG 4326.  What if you make your
extents be in lat/lon instead?
