[mapserver-users] polygon overlay

[Ben Lewis]

All -
Does anyone know of open source code out there for polygon overlay?  I would 
like to do a union on two small shape files within a mapserver application.  
Was thinking there would be something used ascii inputs and outputs.  There 
appear to many code bits, especially in the computational geometry realm, 
but I'm not seeing anything I can compile and use.
