Why maps? Because maps are a visual tool for sharing information with others. Because they can be produced by many people and combined together to tell stories about complex relationships. Because maps are never ﬁnished and only tell part of a story that can constantly be expanded upon. Because power exists in space, struggle exists in space and we exist in space. Because we cannot know where we are going if we do not know where we are from. - Notes for a People’s Atlas of Chicago http://chicagoatlas.areaprojects.com/about/ 2

A thought... “If you don’t make [lower-resolution mapping data] publicly available, there will be people with their cars and GPS devices, driving around with their laptops .. They will be cataloguing every lane, and enjoying it, driving 4×4s behind your farm at the dead of night. There will, if necessary, be a grass-roots remapping.” Tim Berners-Lee 13

How is OpenStreetMap different? 14

“You could have a community capability where you took the GPS data of people driving around and started to see, oh, there’s a new road that we don’t have, a new route .. And so that data eventually should just come from the community with the right software infrastructure.” - Bill Gates 15

\"OpenStreetMap is a project aimed squarely at creating and providing free geographic data such as street maps to anyone who wants them.\" openstreetmap.org 16
