Safety & Emergency Data Methodology
How EnvioGrid sources and presents safety and emergency service information including hospitals, police precincts, and fire stations.
Last updated: May 2025
Data Sources
Safety and emergency data is sourced from:
- OpenStreetMap (OSM): Hospital locations (amenity=hospital), police precincts (amenity=police), and fire stations (amenity=fire_station)
- Official Government Directories: Verified emergency service locations from city and county government websites
Data Presentation
Safety data is presented as a categorized list of nearby emergency facilities. Each category includes:
- Facility name and address
- Distance from ZIP code centroid
- Type of service (emergency room, urgent care, police precinct, fire station)
Important Disclaimer
This data is for informational purposes only. In an emergency, always call 911. Facility information may change — verify directly with each facility before visiting.
Limitations
- Not all facilities may be listed in OSM
- Hours of operation and service availability may change
- Distances are calculated from ZIP code centroid, not from a specific address
