[postgis-users] How to generalize or simplify a Polygon

[Matt Lynch]

Hi,

I have an application where I will be accepting a shape file (polygon)
to define a region of permitted access for a user which will be imported
to postgis.  That shape file has the potential to have many points if
the region defined has a border like a river or lake.  Are there any
functions or tools available that would take a polygon shape and reduce
or generalize the number of points in the polygon?  The resulting
polygon must cover at least as much area as the original.

Thanks,

Matt
