Trusted by public safety, relied on by communities
Features
Built for the Way You Work
The real-time, collaborative map agencies use to create and share evacuation zones, closures, routes, and resources in seconds, then publish the exact same view to the public with a single link. No app, login, or registration required. It becomes your common operating picture for emergency management, fire, law, public works, and PIO teams, integrates with existing Esri data, and keeps an auditable record of every change. Communities using Perimeter get fewer non-emergency 911 calls because people can find answers fast, which helps build lasting public trust.
Integrations
Works with Your Existing Systems
It works with the tools public safety teams already use, so key information stays in one place. Perimeter pulls in data from multiple systems to create one shared, live map that agencies can edit together in real time. Share one simple public link, no login needed, through alerts, social, websites, or QR codes, so the public sees the same trusted updates. It works with Esri/ArcGIS, sends and receives data fast, and connects with alert tools like Everbridge. Export GeoJSON/KML for CodeRED, Rave, and CivicReady to keep alerts and visuals aligned. Admins control publishing, and every change is recorded. Built to work in low connectivity environments.
Use Cases
Daily Operations, Disaster-Ready
Used daily to give the community one view and one message. PIOs publish once and updates are automatically live, which has helped agencies cut 911 information calls by about 40 percent. Used for blue and gray-sky events such as parades, festivals, parking, utility work, street closures, school safety, and routine road incidents, as well as wildfires, floods, debris flows, hazmat, and other hazards. During major incidents, the link reaches residents fast and at scale; for example, a Washoe County wildfire incident reached 2.4 million visits in nine days. Because there’s no app or opt-in and the link can be placed in alerts, social posts, and websites, residents instantly see their location against evacuation zones, routes, closures, shelters, and more.

Plan, Publish, and Act with Authority.
Perimeter Plan and Perimeter Map are built to complement each other. Plan zones, sequences, clearance timelines, and route deconfliction ahead of time. During an incident, your team activates the plan, updates closures and resources, and publishes the same authoritative map to the public with a single link. From planning, response, recovery, and after action analysis, keep everyone aligned from exercises to operations. The result is faster decisions, clearer communication, and a community that knows what to do.
Built for the reality of public safety.
