Refugee camps, such as the Kalobeyei settlement in Kenya, face significant challenges in urban planning due to a lack of spatial data, which impacts the delivery of essential services. To address this, the UNHCR, in collaboration with the Humanitarian OpenStreetMap Team and technological partners like Microsoft, utilized drones and machine learning to map these areas efficiently, turning what would be a lengthy manual process into a much quicker one. The project leveraged GitHub as an open-source platform to share data, models, and code, enabling global collaboration and adaptation for similar scenarios worldwide. This initiative not only helped in planning but also fostered a collaborative environment where refugees, scientists, and developers could work together, creating a reusable blueprint for future humanitarian efforts and empowering displaced communities with sustainable solutions.
