YouthMappers in Action: Disaster Response in Turkey and Syria using OSM
summary
YouthMappers mobilizes university chapters to map earthquake damage using Rapid Editor and Mapillary, Planet and OpenAerialMap imagery, and the HOT Tasking Manager, producing over 1 million buildings added and geotagged damage/collapse points from about 40 mapathons and ~8,000 contributors. Data lands on HDX and is reused by responders. Work succeeds at scale but faces gaps: AI building detection lacks coverage in parts of Syria, AI quality drops in rural areas, Tasking Manager slows on weak connections, and contributor skill is uneven.
