OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. OSM data is openly licensed and contributors can map areas important to them. The OSM map is compiled from data contributed by mappers around the world and integrated with public datasets like TIGER. Mappers can contribute from home or at global mapping events using online tools or GPS devices to add and update map features.

16. Norman Dennison, director of Geographers' A-Z Map Company, confirms that Lye Close is a lie, which will now be removed. "The idea is to put something on the map to protect copyright," he says. "We try to put it in an area or a part of a road which would not be misleading to the ordinary person in the street. They have been put in out-of-the-way places."

20. 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

TIGER Data: T opologically I ntegrated G eographic E ncoding and R eferencing system TIGER/Line®Shapefiles are spatial extracts from the Census Bureau's MAF/TIGER database, containing features such as roads, railroads, rivers, as well as legal and statistical geographic areas. http://www.census.gov/geo/www/tiger/
