OpenStreetMap is a free and open source map of the world created by volunteers. It began in 2004 and now has over 1.3 million contributors who have mapped over 34.5 million km of roads and 91.7 million buildings globally. In Denmark, volunteers have mapped over 99.8% of roads and over 556,000 buildings. OpenStreetMap allows anyone to add and update map data to keep maps current and add important information not included by commercial maps. It also enables "counter-mapping" by communities to represent places not shown on traditional maps.

Commercial maps vs.
OpenStreetMap

Commercial maps update monthly, yearly

Commercial have Quality Assurance

OSM has crowd-ownership

Free downloadable data

OSM-Data is available immediately after save

The critical power of
OpenStreetMap
“Maps as resistance, counter-mappings and
participatory GIS take up maps and politics in an
explicit manner to provide alternative mappings of
space not represented by official state agencies”

Counter-mapping in
OpenStreetMap

Counter-mapping – Critical Cartography

Who is to decide what “important geodata” is?

No secrets - “if it's there, it's there”

Wheelchair accessibility as Counter-mapping act

The Long Tail of
“Frustrated” Talent
Don't think of crowdsourcing participants as
cheap “Mechanical Turks“

They might be experts in the field

You can “transform” their interest, not dictate
their work
