What's Different

If you are familiar with OpenStreetMap you may want to know what's different about fosm and learn why you should contribute to fosm rather than OpenStreetMap. This page summarises the main differences.

Differences

• The main difference is, of course, the license. Fosm content is licensed under the Creative Commons CC BY-SA license rather than OpenStreetMap's combination of Contributor Terms (CTs), Open Database License (ODbL), and Database Content License (DbCL). We think our license is much simpler and easier to understand. It relies on copyright which is the traditional mechanism for protecting maps and follows well known and understood legal principles.
