Map slums around the world - Maps are a vital component of activities to improve slums and the lives of slum dwellers. Let's work together to increase the quality and quantity of data on slum areas and the areas' visibility through mapping.
Crisis in the Horn of Africa - Help create detailed maps using your local knowledge of places, such as cities, roads, bodies of water and other natural landmarks. The map data that you contribute will be shared periodically with the UN agencies which are engaged in this crisis.
We've seen some very fun and successful events so far and would love to learn about more! The events have helped us gather feedback to improve Map Maker and have also helped users make friends and learn from each other.
