RouteMe: A native slippy map for the iphone. Project documentation is all here: http://code.google.com/p/route-me/ For news and updates and help, join our mailing list: http://groups.google.com/group/route-me-map There are two subdirectories - MapView and Proj4. Proj4 is a support class used to do map projections. The MapView project contains both the route-me map library and a simple example application which embeds the map. Refer to the embedding guide for details: http://code.google.com/p/route-me/wiki/EmbedingGuide
