Open Street Map
OpenStreetMap (OSM) is a collaborative project to create a free editable map of the world. Two major driving forces behind the establishment and growth of OSM have been restrictions on use or availability of map information across much of the world and the advent of inexpensive portable satellite navigation devices.
Founded by Steve Coast in 2004, it was inspired by the success of Wikipedia and preponderance of proprietary map data in the UK and elsewhere. Since then, it has grown to over 900,000 contributors, who collect data with GPS devices, aerial photography, and other free sources. This crowdsourced data is then made available under the Open Database License. The site is supported by the OpenStreetMap Foundation, a non-profit organization registered in England.
Rather than the map itself, the data generated by the OpenStreetMap project is considered its primary output. This data is then available for use in both traditional applications, like its usage by Craigslist and Foursquare to replace Google Maps, and more unusual roles, like replacing default data included with GPS receivers. This data has been favorably compared with proprietary datasources, though data quality varies worldwide.

Famous quotes containing the words open, street and/or map:
“It is an open question whether any behavior based on fear of eternal punishment can be regarded as ethical or should be regarded as merely cowardly.”
—Margaret Mead (1901–1978)
“Everybody has that thing where they need to look one way but they come out looking another way and that’s what people observe. You see someone on the street and essentially what you notice about them is the flaw. It’s just extraordinary that we should have been given these peculiarities.... Something is ironic in the world and it has to do with the fact that what you intend never comes out like you intend it.”
—Diane Arbus (1923–1971)
“The Management Area of Cherokee
National Forest, interested in fish,
Has mapped Tellico and Bald Rivers
And North River, with the tributaries
Brookshire Branch and Sugar Cove Creed:
A fishy map for facile fishery....”
—Allen Tate (1899–1979)
