[mapserver-users] GEOMTRANSFORM definition causing an error

[Stephen Woodbridge]

So according to this:

http://mapserver.org/development/rfc/ms-rfc-89.html  Section 2.2

You GEOMTRANSFORM at the LAYER level is expecting your buffer value in 
ground units, do you really want to buffer your parcel by 150 degrees?

Maybe you want to do something like Section 2.3?
