OpenStreetMap is a collaborative project to create a free editable map of the world. It was founded in 2004 in response to expensive ordnance survey data and has grown to over 300,000 registered users worldwide who contribute geographic data through GPS, aerial imagery and existing public sources. This crowdsourced mapping data is used by the Humanitarian OpenStreetMap Team for humanitarian and development purposes, including assessing exposure to natural disasters through their Risk-in-a-Box tool.
