[OSM-dev] Austrian National Grid <-> latlon

[Nick Whitelegg]

Thanks everyone for input to this. Got proj4java working on android, after removing the AWT dependencies, and works fine with EPSG:3785 (google mercator) and 27700 (OSGB). Given the German projections seem a little simpler I might use EPSG:31469 as it seems to cover the Vienna area.
