Everyone you alerted, on real mapping, colour-coded by what they need. Layers for urgency, crowding and movement, your own venue annotations, a what3words grid, switchable basemaps, and draw-around-people-to-message-them.
Where It Is
Open the incident under Incidents → Active Incident and choose the Map tab. It shows every person across all of that incident's active alerts on one map, updating live as positions arrive.
Pop it out. The map opens in its own window for a second monitor, which is where it belongs during a long incident. The pop-out doesn't join your voice rooms a second time, so opening it never changes what you can hear. It stops being a map the moment the incident closes — a window still drawing pins after a stand-down reads as people who currently need help.
Where Positions Come From
The response page — A satellite fix from someone's browser, refreshed continuously if they're sharing live.
The apps — Continuous position from iOS and Android, which keeps going with the phone in a pocket. See Live Location & Privacy.
A text message — Someone with no app and no page can simply text their location to the alert's number: a Google Maps or Apple Maps share link, a ///what3words address, or raw coordinates. Each is resolved and dropped on the map.
Reading a Pin
A pin's colour is what that person needs from you, not what they said. Warm colours are people who need someone; cool colours are people who are accounted for. Red is act now and nothing else, so an evacuating building never reads as a casualty list.
Red — Need help. They asked for help and a distress case is open.
Slate — Can't respond. They said they cannot speak: treat it as urgent until you know why.
Orange — No reply. Becomes urgent once the alert has been running past its response window.
Yellow, with a ? — Unclear. They replied, but not in a way that reads as safe or not, and were asked again.
Sky blue — Evacuating. Moving to safety and keeping you updated: accounted for, not a call for help.
Blue — Acknowledged. They have seen the alert but not said how they are.
Green — Safe.
A pin's age shows in how it's drawn: fresh positions pulse at full strength, then fade with age, then go grey once they're too old to trust. A position from an hour ago never looks like a position from thirty seconds ago.
Layers
Everything below is a separate toggle in the Layers menu, and your choices are remembered between incidents.
Status colours — Colour each pin by what that person needs.
Group nearby — Cluster bubbles carrying a ring that shows their make-up. On by default. Anyone urgent, or anyone you're focused on, is never hidden inside one.
Urgent heat — A red bloom over clusters of people who need someone now. Deliberately not everyone who is merely not-yet-safe: an evacuation would otherwise bloom over its own exit route.
Crowd — Density cells with a flow arrow per cell, for reading where a crowd is and which way it's moving.
Crowd counts everyone — With Crowd on, the cells keep counting the whole crowd while the status filter narrows the pins.
Trails — Where each person has been over the last four hours.
Accuracy — The ±N m disc under each satellite fix. Off by default, because at evacuation density it's the largest thing on the map and washes out everything above it. The figure is in each pin's tooltip either way.
what3words grid — The what3words 3 m grid, drawn from zoom 18.
Your Venue Annotations
At the foot of the Layers menu, under Venue annotations, is one switch for each group your team has drawn on the venue map: exit names, sections, fire routes, muster points, cordons. They sit under the live positions as part of the ground, so a name or a shaded area never covers a person.
What shows first — A group marked On by default is drawn the first time someone opens the map. After that each person's own switches are remembered on their device and always win.
Close-range labels — Annotations held back to close range appear as you zoom in, so a site-wide view is not a mat of text.
Names and notes — Hover over an annotation to read its name, its group and any notes.
Who sees them — Everyone who can open the incident map. Venue annotations are never shown on the public response page.
Changes — Edits made on the venue map appear the next time the incident map is opened.
A thousand green dots is not what you look at to direct help. The status filter narrows the map to the people you care about — Everyone, Only people needing someone, or any combination of states you tick. With the map full-screen or popped out, H shows only the people needing someone and A brings everyone back. Press / anywhere to search for one person by name.
The filter is deliberately never remembered between sessions, and if it's hiding somebody urgent the map says so in a banner — working from a picture with a casualty filtered out of it is the one thing this control must never let you do.
Choosing the Mapping
The basemap is a switch on the map itself, changeable mid-incident, and swapping it leaves every layer above exactly where it was.
OS Road — Ordnance Survey. The most street detail available, Great Britain only.
OS Outdoor — Ordnance Survey paths, terrain and rights of way. Great Britain only.
OS Light — Ordnance Survey in muted tones, so pins and crowd cells stand out. Great Britain only.
OpenStreetMap — Worldwide; detail varies by area.
MapTiler Streets — Worldwide, consistent detail.
Satellite — Worldwide aerial imagery.
Ordnance Survey is the best mapping there is for Great Britain and completely empty everywhere else — so an incident outside GB on an OS basemap is a blank grey field at the moment you need it most. whoot. notices and offers you a worldwide style, but the switch is yours to make. Note that Northern Ireland and the Isle of Man are not in OS coverage.
what3words
Turn on the what3words grid and the 3 m grid is drawn over the map from zoom 18. Click any square to pin it and read its ///address — useful for giving a responder or an emergency service an exact spot with no street to name. Click it again to dismiss. It's a click rather than a hover, so a lookup is always something you meant to do.
Draw Around People and Message Them
Turn on Lasso and draw freehand on the map. Everyone inside what you drew is selected, and you can then send that exact group a message — "do not use the north stairwell" — without picking names off a list.
Draw a loop and it selects everyone the loop encloses, including loops that cross themselves.
Draw a line — along a road, a fence line or a platform edge — and it selects everyone under the band you drew.
The message goes out over the same two channels as any other update: to everyone's response page, where it's free and read-receipted, and/or by SMS. Every lasso send is written to the incident timeline with the shape you drew and the people it caught.
Movement Trails
The Trails layer draws where each person has been, fading toward where they came from so it's obvious at a glance which end is now. It reaches back four hours, and a handful of trails are drawn at once until you ask about somebody specific — forty overlapping journeys is not a picture anyone can read.
What's drawn is not the raw fixes. Satellite error over fifteen seconds is comparable to the distance a person covers in that time, so joining the dots would draw agitated pacing wherever somebody actually stood still. Trails are conditioned into movement, stops and gaps first — a stop is shown as a stop.
How long trail history is kept is your decision, set in Settings → General. See Live Location & Privacy.
