Simplification and Gridding
Simplifier is a Manifold Map script that implements a set of different methods for topological simplification of a planar-enforced polygon drawing.
The code (map file) can be downloaded here
To understand what it does see the presentation on Gridding and Simplification (Presentation on techniques for modifing/splitting of large polygons that demonstrate slow performance when being geoprocessed (intersected).) I gave at the Oracle Forum in Sydney in August 2008.
