NOMAD Field Desk v7.2.0 — Location-aware Situation Room

Near You — location-aware Situation Room

The global Situation Room can now filter threats by distance from your home.

Proximity Board

A new top-of-dashboard card shows a 4-bucket ring of active events:

• < 50 km immediate
• < 200 km regional
• < 500 km default situational awareness
• < 2000 km wide-area

Below the rings: a nearest-first list of active events with distance + compass bearing (e.g. "23 km NE"). Event types covered: seismic, severe weather, fires, disease outbreaks, volcanic activity, armed conflict, OREF sirens.

New Settings row

Home Location — latitude, longitude, radius selector, plus a Detect button that uses the browser geolocation API. Coordinates are reused by existing weather and sunrise/sunset features.

Empty / error states

• No coordinates set → board shows a prompt card with a button to open Settings (not an empty grid).
• Coordinates set, no threats within radius → green "All clear within X km" message.
• Fetch failure → "Proximity data unavailable" fallback.

Under the hood

• GET /api/sitroom/proximity aggregates from the existing sitroom_events table — no new background fetcher needed.
• Haversine + bearing helpers in situation_room.py, unit-tested against the published NYC→LA great-circle distance.
• SETTINGS_WHITELIST extended with latitude, longitude, proximity_radius_km.
