The document summarizes Map Kibera, a project that mapped Kibera, one of the largest slums in Africa located in Nairobi, Kenya. The project engaged local residents to map their community using open source tools. Over a period of two years, the project recruited and trained local mappers, mapped the entire slum, developed skills in community members, and connected them to service providers to increase accountability. The goal was to empower the community by mapping and gathering local information that could be used to advocate for their needs and voice their perspectives.
