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 full-resolution photo stamped with location and compass direction. 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, find and event over time - at up to 120×, looped between the moments that matter.
Messages and orders
Message one searcher, a team or everyone. Orders must be acknowledged on the phone, so you know who has read them.
Phone signal and battery
See where phones lost signal - over a ridge, down a valley - as a map, and whose battery is running low before they go quiet.
Audit pack
One download for the record: every track as GPX, finds with full-resolution photos and their location data, and the mission log.
Built for how searches really run
Manage and see every search location in real time, whatever the job.
Urban vehicle searches
Crews drive street to street while base watches every road being covered in real time, so no street is missed and none is searched twice.
Sectorised searching
Split the ground into sectors, send each team theirs on their phone, and see progress in each sector as it happens.
Large teams
From a handful of searchers to teams of 100 or more. Everyone is on one live map, grouped by team, so base can manage them all.
Door knocking
See which streets have been covered and where each team is now, as the canvass moves through a neighbourhood.
Evacuations
Track crews going street to street, see which areas are cleared, and redirect people quickly as the situation changes.
Missing people
Elderly people who have wandered, lost children, or overdue walkers: share the photo and description to every phone and search the likely areas fast.
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 - or play solo:
- Race to each target, or Tour for the shortest route
- Hunt with P1-P3 priorities, to practise triage
- Cat and mouse: the hidden team shows only in pulses
- Land grab: close loops to claim ground, and steal it
- Targets as pins, coordinates, directions or a distance; clues to answer on site
- Cars worked out from how phones move; scheduled starts
- Live scoreboard, opponents on the phone, printable sheets, replay
Practise freely
A safe place for new members to learn the app and the map before their first search.
The games
Pick one when you set up a training night. Teams play from the app, in cars or on foot - or on their own.
Race
First to each target
One target at a time. The first team to reach it scores, then the next target appears for everyone.
Good for: Fast, head-to-head driving; short sessions; learning the area.
Tour
Visit every target, shortest distance wins
Every team must visit every target. The team that finishes having travelled the least distance wins - so plan the route.
Good for: Navigation and route planning; one-at-a-time and staggered orders for fairness.
Hunt
Find all you can, any order
Every target is open at once; teams find as many as they can before time is up. Give targets priorities (life threat, urgent, routine) for triage training.
Good for: Scenario training - dealing with the most urgent jobs first; scavenger hunts.
Land grab
Close loops to claim land
Walk or drive a closed loop and your team claims all the land inside it. Land can be stolen by another team's loop. Most land when time is up wins.
Good for: Covering ground, teamwork and tactics; walking or cycling groups.
Cat and mouse
Hide, then show only in pulses
Add to any game: the other teams show on your phone only every few minutes, as a pulse - or when you get close to where they were last seen.
Good for: Tracking and pursuit; thinking ahead of where a team will be, not where it was.
