In disaster scenarios, reliable communication is crucial. A solution for offline disaster relief coordination is presented, using OpenStreetMap vector maps hosted with FastAPI on a Raspberry Pi, which provides a WiFi hotspot. Street and location names are extracted from OpenStreetMap data to enable location searches. The system can be extended by using a LORAWAN gateway to receive positional information from disaster relief workers.
All the knowledge required to host such a map server will be provided.
