[mapserver-users] mapserver, msProjectPoint() error

[Stephen Woodbridge]

I think this error is caused because you have a layer with data defined 
in lat,lon and it has coordinatesgreater than +-85.0511287776451 degrees 
of latitude or > 180.0 or < -180.0 long.

Coordinates outside that range will generate this error.
