In places where data on critical infrastructure is hard to access, street-level imagery offers a low-cost and verifiable alternative. By building on tools like Mapillary, we explore how visual cues, like school signs or facility names, can support disaster resilience through open, community-led data collection.

Our two-day UPRI YouthMappers x TomTom mapping party focused on adding missing speed limits to OpenStreetMap, with 20 participants contributing 399 updated highways using Mapillary and KartaView. We discovered gaps in speed limit data near toll exits, gas stations, and U-turn slots, encountered funny AI misdetections, and enjoyed a fresh perspective on mapping beyond roads and buildings.
