Hi, I'm just starting out actually manually mapping with OSM (not addicted yet, but give me a little time), and I've been helping out with Development Seed's addition of Africover data to undermapped African areas.

OpenStreetMap is a free editable map of the whole world. It is made by people like you.

OpenStreetMap allows you to view, edit and use geographical data in a collaborative way from anywhere on Earth.

OpenStreetMap's hosting is kindly supported by the UCL VR Centre and bytemark.
