Survey of Slum Housing Characteristics Using Drones: An Experiment in the Alto das Pombas Community, Salvador de Bahia/Brazil

Drone-based photogrammetry offers a low-cost, rapid solution for gathering detailed urbanistic data on slum housing, as demonstrated in a study of the Alto das Pombas community in Salvador de Bahia, Brazil. The research found that drone surveys could effectively identify and quantify precarious housing structures, prioritizing them for health improvement interventions. By processing aerial imagery, the study extracted key physical characteristics of households, providing actionable insights for municipal programs aimed at upgrading slum infrastructure under Brazil's Federal Technical Assistance Law. This approach holds promise for scalable implementation in other informal settlements.
