Hi, I remember a discussion a few weeks ago about the need for vectorization of rasters in geotools. Andrea Aime pointed to some JGrass code (port of Grass' r.to.vect) and people offered to test the algorithm for Geotools.
I also need this badly, so I gave it a try and made a geotools-compatible class, which tests satisfactorily so far. The code is self-contained (in a geotools environment) and contains a main() with some minimal testing code. It can be made a lot smarter, but it works ok as a proof of concept. If anyone wants to see it, it can be found on our fisheye server: http://ecoinformatics.uvm.edu/crucible/browse/ThinklabGeospacePlugin/org/integratedmodelling/geospace/gis/Vectorizer.java I'm also going to start work on a rasterizer - which is likely to be dumb, as I'm definitely not the spatial algorithm guru, but after 12 years in the USA I have no shame left and I'll post what I come up with anyway :) Suggestions for algorithms or pointers to existing code are of course welcome.
