Before August 2016, this structure along a dirt path was the only building in the area. People often gather in the shade of large trees. Solar panels help charge smartphones. Houses are typically made of mud or plastic sheeting. Fields are burned to prepare for new crops. To create a digital map, features such as roads and build- ings are traced from satellite images. Business* As pharmacies, restaurants, convenience stores, and other shops open, they’re added to the map, along with their hours. Place of worship Many churches have been established and mapped in Bidibidi, along with a number of mosques. *Dots represent unidentified shops. Medical facility Clinics and health centers are described by how they’re constructed and how many doctors and nurses are on staff. School Information includes when a facility opened, whether it’s permanent, and how many teachers work there. KEY FEATURES 0 feet 300 0 meters 100 NN PUTTING BIDIBIDI ON THE MAP Three years ago the area containing the Bidibidi settlement was a forest in northwestern Uganda. Now, as this satellite image shows, it’s a makeshift home for a quarter million refugees from South Sudan. Armed with smart- phones, some of them are helping to build an online map of schools, clin- ics, businesses, and water sources. The effort is led by the Humanitarian OpenStreetMap Team, which creates free and publicly edited maps of crisis zones. The aim? To give refugees a guide to their home and the power to change it. Aid workers use the data to manage the quickly evolving camp.
