This page is a collection of OSM related resources and links. For the official OpenStreetMap site, go to openstreetmap.org.

What is OpenStreetMap?

OpenStreetMap is a global volunteer effort to create map data and give it away for free like Wikipedia.

Examples of who uses OSM maps:

  • Humanitarian Organizations: Organizations such as the Red Cross and Doctors Without Borders use OSM maps to fight disease outbreaks (such as ebola and cholera), and to respond to natural disaster crises.
  • Companies: Companies who use maps in their websites (Geocaching, FourSquare).
  • Individuals: Anyone who wants access to the raw data, or anyone who wants to print maps and have explicit permission to do what they want with them!
