Mapping for the masses

Open Street Map project is an interesting open source project. Where the community is building a collection of mapping data, which is licensed CC by SA . The project which has a large following in Europe is just starting to expand in the USA with the start of integrating the freely available TIGER data sets, which promise to provide a good base coverage for the whole USA. Supporting the project many innovative tools have been built and function, including a google style map browser known as Slippy Map, an web based editor Potlatch, and a very capable java based editor JOSM . Go check out their maps at either http://openstreemap.org or http://informationfreeway.org
