OpenStreetMap is a free and open source map of the world. It is often referred to as the Wikipedia of Maps. It’s is maintained by hundreds of volunteers throughout the world and relies on individuals to make corrections and updates to the map. Users are often told to map what they find interesting so in many cases you find data and information contained in it that is not found on other maps of geographic information systems.

With budgets being tightened and organizations forced to be creative in how they obtain and maintain data, this is a resource with which you should become familiar.

  • OpenStreetMap Book – This book is dedicated to newcomers interested in collaborative mapping who have not yet gotten their hands on OpenStreetMap. Though we wanted to make this book accessible for beginners, advanced users will also find more complex information in the last two sections. It was written during a three-day book sprint held during the Google Summer of Code Documentation Summit in Mountain View, California between the 18th and 20th of October 2011. The team consisted of a group of six co-authors (developers, users, trainers and beginners), Kate Chapman, Ian Dees, Anne Gentle, Shaun McDonald, Nóirín Plunkett and  Tomi Toivio, and was facilitated by Anne Goldenberg of FlossManuals-fr.
