Most of the readers might be used to use their gps powers smart phone to look up directions on a detailed and up to date map. However, this does not exist everywhere. In the slumps of our world there is a lack of good maps, which are essential for economic prosperity (like deciding what kind of infrastructure to build). Using OpenStreetMaps, a collaborative tool to make maps, volunteers from the Humanitarian OSM Team go around the globe to create maps. These collaborative maps can be used by aid and development agencies.
