HUD at a glance

The map uses the Sentinel Dark basemap: deep background, subtle roads, and cyan mesh lines from the gateway to visible nodes.

Corners show cursor coordinates, gateway status, active node count, and a short tactical event log.

The tactical map is the central view of Sentinel: what an operations center sees on its 24/7 monitors. It is built to be read at a glance, with no unnecessary visual noise. That's why it uses the Sentinel Dark style: deep background, dimmed roads, minimal labels, and color reserved for actual operational signal.

The HUD (Heads-Up Display) occupies the four corners with always-visible data. Top left: real-time cursor coordinates—handy when someone passes you a position over the radio and you need to verify it. Top right: gateway status and active node count. Bottom left: tactical log with the latest events (movements, alerts, geofence transitions). Bottom right: contextual shortcuts based on what you have selected.

The underlying idea is to separate 'what's happening now' from 'what I do about it'. The map shows; the side panels (which open with a click on a unit or via the command palette) act. That separation reduces errors under operational pressure: if you have to dispatch a mission during an SOS, you don't get lost in menus—the map stays visible while you work in the side panel.

For new teams, a good training practice is to project the map on a large screen during a shift and simulate events: mark duty, enter and exit geofences, trigger a test SOS. That early familiarization pays dividends when the first real incident comes, where every second of delay matters.
