In my opinion, the plugins should work in cartesian coordinates. I've written some scripts, which I will release in the winter holiday. I hope, someone is going to port them to JAVA. Cartesian Coordinates are in a rectagular coordinate system and it's easy to calculate with vectors and trigonometry. Since JOSM is used for short directions 90% of the time, the error rate will be very low ... up to 10 km it's some centimetres. Cartesian Coordinates are the basic of any transformation process, the JOSM could work with any projection: 90° would always be 90° and a circle would always be a circle - internal of course, not on screen :-) _______________________________________________ josm-dev mailing list josm-dev@openstreetmap.org http://lists.openstreetmap.org/listinfo/josm-dev
