Know where every searcher is, and what ground is covered.
Meridian SAR tracks your search teams live, shows the ground covered and the gaps left, sends search areas to their phones, and lets you run realistic navigation training - from one command screen.
Built for USAR SAR units, Police search teams and Volunteer SAR groups.
Years in the making, with careful deployment.
Everything a search needs, on one screen
From a handful of volunteers to hundreds of searchers, Meridian SAR keeps the picture current - and keeps working when the signal does not.
Live positions and trails
Every searcher on the map as they move, with their route. Zoomed out it groups them; zoomed in it shows every street they walked.
Coverage, and the gaps
Ground covered builds up as a grid, darker where searched more - so the areas nobody has reached stand out.
Search areas to every phone
Draw sectors on the map and share them with the teams. Updates reach their phones automatically, and stay there offline.
Finds, with photos
Searchers mark what they find where they find it, with a photo. It appears on the command map at once - and waits on the phone until there is signal.
Volunteers join with a code
Hand out a mission code; volunteers join from the app in seconds - no account needed - and show up grouped on your map.
Works out of range
Phones keep recording with no signal and send everything when they are back in range - to the right search, never another.
Situation screen
A full-screen map for the command post: who is searching, how they are travelling, who has gone quiet, and the latest finds.
Replay for the debrief
Play back every route, target and event over time - at up to 120× - to review what happened and learn from it.
Up and running in minutes
No hardware, no radios to pair. Phones your team already carries.
Create a mission
Name it, draw the search areas, and get a mission code - plus an authentication code for missions that are not open to the public.
Searchers join from the app
They enter the code, say how they are travelling - on foot, bike, vehicle, horse, boat - and start. Their phone does the rest.
Coordinate it live
Watch positions, coverage and finds as they happen; share or change areas; spot anyone who has gone quiet.
Real searches, training nights, and practice
Every mission is one of three kinds, labelled everywhere so a drill is never mistaken for the real thing.
The real thing
Live tracking, coverage, areas and finds for an active search.
Navigation games
Set targets on roads or hidden in a park and run timed games for your crews:
- Races to each target, or tours for the shortest route
- Targets as pins, coordinates only, written directions, or just a distance
- Clues to answer on site, checked by the controller
- Live scoreboard for base, printable team sheets, replay
Practise freely
A safe place for new members to learn the app and the map before their first search.
