Offline navigation app CoMaps aids rescue efforts during Venezuela earthquake response
Technical upgrades to the open-source software allowed emergency responders to access weekly map updates in zones without cell service.
The short version
- First responders and volunteer rescue teams in Venezuela utilized the open-source offline navigation app CoMaps to coordinate logistics in areas with no cellular coverage.
- Recent infrastructure upgrades decoupled map updates from app updates, reducing map processing time from 10 days to 3 days and allowing weekly global updates.
- The updates successfully delivered critical geospatial data, including thousands of volunteer-mapped buildings, to on-the-ground humanitarian organizations.
Key facts
- CoMaps is an open-source, non-commercial navigation application built on OpenStreetMap data that operates fully offline using a device's GPS once maps are downloaded.[Hacker News]
- The app was used during the earthquake response in Venezuela by local responders and international rescue units, including firefighters and Civil Protection from El Salvador.[Hacker News]
- CoMaps recently updated its systems to separate map updates from the app store review process and utilized a more powerful server, reducing processing time from 10 days to roughly 3 days.[Hacker News]
- The faster processing enabled weekly updates containing thousands of newly mapped buildings generated by volunteers through the Humanitarian OpenStreetMap Team (HOT) Tasking Manager.[Hacker News]
- The platform allows humanitarian organizations such as Techo and the Red Cross to navigate and utilize OSM data directly in the field without needing specialized geospatial analysis expertise.[Hacker News]
What remains uncertain
- It is not yet determined when CoMaps will achieve its future goal of implementing region-specific updates every 12 hours during active emergencies.[Hacker News]
