OpenStreetMap is the free and open wiki map of the world made by millions of volunteers whoíre just like you. Contributors use paper, pens, GPS devices, phones and laptops to capture the world around them (like a street name and location) and then upload it to OSM. The map data is then given away for free, all just like wikipedia. This book contains 15 interviews conducted by OSM founder Steve Coast with the people who were there as the project began and grew. Starting in 2004, the interviews trace how a rag tag collection of volunteers was able to produce a map which compares in quality to maps produced by multi-billion dollar corporations. Learn how such an ambitious project got started and then succeeded at mapping the world, for free!
