State of the Map is alive and well
Puneet Kishor, June 11th, 2013
About 400 map makers, coders, cartographers, designers, business services providers and data mungers of chiefly spatial persuasion gathered in San Francisco to “talk OpenStreetMap, learn from each other, and move the project forward.” These conference attendees are a tip of an iceberg composed of 1.1 million registered users who have collectively gathered 3.2 billion GPS points around the world since OpenStreetMap was launched in 2004 as a free, editable map of the whole world. Unlike proprietary datasets, OpenStreetMap allows free access to the full map dataset. About 28 GB of data representing the entire planet can be downloaded in full, but also is available in immediately-useful forms like maps and commercial services. OpenStreetMap is open data licensed under the Open Data Commons Open Database License (ODbL) with the cartography in its tiles and its documentation licensed under a CC BY-SA 2.0 license.
The program ranged from building and nurturing OSM communities, to technical wizardry, to improving infrastructure. Martijn van Exel provided an insight into the OSM community in the United States (see table below). Big countries and large areas pose challenges already in the queue to be tackled.
