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
Talent
10 of OSM-DK's 100 most active are cyclists
The overall #3 in DK is a women, cyclist & retired
teacher
(1 & 2 are bulk importers/robots)
>6% of total data in OSM-DK 2012

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
