Jeremy asked me to write him a quick 'n' dirty parcel digitizer. So I did it! (silly me). This is to take scanned plat maps, register them against vector data, and then transfer traced parcel polygons to the vector projection (currently LatLon in Decimal Degrees). Later the parcels can be exported to a shapefile for easy manipulation.
This was written in Java 1.5 using BBN's OpenMap and the Matrix Toolkits for Java for homography craziness.
craft.tar.gz or craft.zip is a game I made. It requires the Allegro graphics library. Enjoy!
