Unified Command

Run every incident from one live map.

For security, fire, police and medical.

The incident management and dispatch tool for your unified command office. Every incident is pinned to the georeferenced CAD site plan. NIMS/ICS-aligned, camera-integrated and audit-ready, from load-in through load-out.

A unified command office: a police officer and a fire marshal read MasterGrid Command on the wall screen, an incident pinned to the site plan beside its report, with live camera feeds of the gate queues on the screens to the right

Unified Command

Plan. Operate. Respond.

Built for the unified command office, not the back office. Security, fire, police and medical read one screen.

One plan on the wall. Incidents, posts, cameras, exits and gates on the same georeferenced site plan.
Reported from where it happened. Anyone on the crew drops an incident from the phone basemap.
A record that holds up. Every open, edit and note logged, incidents locked on resolve, reports with response times against targets.
The posts on the same map. Every guard position a dot, with its shift and who is filling it.

How it works

NIMS/ICS-aligned. Camera-integrated. Built for the report you’ll have to defend.

Drop an incident exactly where it happened

Right-click anywhere on the geo-referenced CAD site plan and pick a track. The incident drops as a pulsing, geo-located marker — no address guesswork, no “somewhere near the second bar.”

Right-click the plan. A track picker opens where you clicked — Security, Medical, Guest Services, Operations.
Place it from the field, on a phone. Staff on the ground drop incidents straight from their phones — pinned to the exact spot where it’s happening.
Every incident carries its location on the plan. Direct security to the exact spot, not “near the second bar.”
See the cameras placed in Networking as a layer on the same map.

MasterGrid Command: a live event site map with georeferenced incident markers across security, medical, guest services and operations tracks, a right-click track picker, a layers panel for cameras, exits and gates and CAD overlay, and a live incident table under a green alert banner.

Try it. Nothing you type leaves this page.

Five-tier alert system

Event-wide. One shared posture, set from Command. Click a level to set it.

Alert level: Green All clear. Normal operations.

Structured triage

The same shape every responder knows, so nothing falls between tracks.

Severity

Status workflow

Operational tracks, Security/Command, Medical, Guest Services and Operations, with 30+ incident categories underneath. MCI levels 1 to 4, patient counts, and transport tracking when a medical event scales.

NIMS/ICS structure

Operational tracks — Security/Command, Medical, Guest Services, Operations. 30+ incident categories and four severity levels, on a status workflow your team already understands.

Medical & MCI

Mass Casualty Incident support to NIMS/ICS — MCI levels 1–4, patient counts, and transport tracking — so a surge is structured, not chaotic.

Evidence chain

Witness statements and evidence captured per incident. Every open, edit, and note is logged to an activity trail; incidents lock on resolution, so the record can’t be quietly changed.

Automated reports

One-click PDF incident reports, built for insurers, local authorities, and legal proceedings. The report you produce is the one you can stand behind.

Camera integration

Cameras placed in Networking appear as a layer on the Command map, beside the incidents — no second system to open.

Map & table views

Live incident markers on the map — active ones pulse — plus a table you can filter by track, severity, and status. The whole operating picture, two ways.

Deployment Posts, coverage & signage

Dot map the posts. Staff the shifts. See the gaps.

Every post is a dot on the site plan. Drag it to where the guard stands, name it the way the radio calls it and set the headcount. A post with no position is listed as Not placed until you drop it on the map.
Shifts are reusable times: day, night or overnight. Coverage is one day on one post on one shift with its own headcount, so six on Saturday and four on Sunday sit on the same post.
Gaps show as a count on the map, the coverage board and the report. Assign a person, a department or a vendor, one at a time or in bulk, and give a contractor a share link to their part of the plan.

The Basemap Deploy tab: security, medical, usher and traffic posts listed with their shift and who is filling them, the gaps flagged with a count, two posts marked Not placed, and the placed posts as numbered dots over the satellite image of the site.

Crowd Density Calculator

See the shape of a problem while it’s still on the drawing

Draw any area on the map. MasterGrid fills it with a to-scale crowd — one dot, one person — at the density you set, grades it against Fruin Level-of-Service, and flags where crush risk begins. Place the gates and read clearance time against the 8-minute rule, including a lost-largest-gate scenario.

The Crowd Density Calculator in MasterGrid: a to-scale crowd drawn over the main-stage viewing area, shaded green through amber to red with the dense front-of-stage flagged Peak · Very dense — headcount 10,410, peak 3.0 ft²/person, mean 6.9 ft²/person, 21% floor free at peak, and egress gates clearing in 5.0 minutes.

Level of Service Fruin, 1971

A B C D E F

A · Free flow D · Restricted F · Crush

Crowd density is read in people per square metre. Crush risk climbs sharply above ~4–5 people/m². The trigger is density, not panic.

Comfortable LOS B

~1.5 /m²

Free, easy movement

Restricted LOS D

~3 /m²

Movement constrained, shuffling

Crush risk Crush risk

~6 /m² LOS F

Involuntary contact, pressure builds

Same drawn area, three densities. Figures illustrate each state — not exact band cutoffs.

Grounded in the science

Fruin’s Level-of-Service (A–F) — the framework crowd-safety practitioners actually use.

Included on every tier

Crowd and egress analysis is included on every tier, including Free.

A planning aid, not a clearance. The crowd density calculator estimates — it does not assess. It informs planning and discussion; it is not a substitute for a qualified crowd-safety professional, a formal crowd risk assessment, or real-time monitoring on the day. Treat every figure as a reason to look closer — never as a sign-off.

FAQ

Questions operators ask

Is Command NIMS/ICS-aligned?

Yes. Operational tracks for Security/Command, Medical, Guest Services and Operations, alert levels from Green to Black, MCI levels with patient counts and transport, an activity trail that locks on resolve, and incident reports with response and resolution times against targets. Command follows NIMS/ICS practice; it does not replace what your AHJ requires.

Can I map security posts on the same plan as incidents?

Yes. Deployment posts sit on the Basemap as dots, each with its shift, headcount and who is filling it, on the same plan as the incident markers, cameras, exits and gates. Anyone on the crew reports an incident from the phone basemap from where they are standing.

Can I export incident reports for insurers and authorities?

Yes. The incident report carries the critical count, average response and resolution time against targets, a timeline, the severity mix, a response-area breakdown and the full register, as a PDF you can hand to an insurer, an authority or counsel.

Is the crowd density calculator a substitute for a crowd-safety assessment?

No. It is an estimate and a planning aid. It does not replace a qualified crowd-safety professional, a formal crowd risk assessment, or real-time monitoring on the day. It is included on every tier.
