Founded in the UK in 2004, inspired by the success of Wikipedia and crowd sourcing information, OpenStreetMap aims to map the world as open data.

The project came into it's own during the 2010 Haiti earthquake where volunteers used available satellite imagery to map the roads, buildings and refugee camps of Port-au-Prince in just two days, to create the most complete digital map of Haiti.

Harry Wood, developer at transportAPI.com, and on the board of the Humanitarian OpenStreetMap Team, introduced us to OpenStreetMap, looking at how volunteer mappers helped with disaster response in the Philippines after Typhoon Haiyan.
