Search & rescue · incident command
SAR Mission Planner
The app predicts and executes what the search needs: who is missing and what they look like, how urgent it is, the units the operation must have, the first-hour reflex tasks, the investigative branch, the probability matrix the sweeps update, and the checklist every operational period must pass. Everything here lands on the ICS-214 ledger. Not legal or medical advice.

Urgency & survivability
What the operation needs
Recommended from the urgency band, subject count and terrain flags; compared with the seats on the crew call. Missing seats are one tap away — then broadcast from the console.
First 60 minutes · reflex tasks & containment
Investigative intelligence
Mobility · distance over time & transport exits
Four formulations run on the primary subject's category and the hours since the PLS: theoretical maximum containment Rmax = vmax·Δt (the perimeter for roadblocks and spotters), Tobler's terrain-adjusted reach per bearing v(s) = 6e−3.5|s+0.05| (enter the grade along each bearing; a DEM cost-path in CalTopo / SARTopo refines it), disoriented random-walk diffusion Rrms = 2√(D t) with Rayleigh quantiles, and the ISRID mobility window Deff = veff·min(t, Tmobility) capping the category's percentile rings. High-velocity exits — highways, bus, rail, air, ferry — are scored by whether the subject could already have reached them. Planning aid, not a guarantee: verify against the DEM and the terrain.
Probability matrix · POA × POD
Initial POA per sector from the primary subject's lost-person-behaviour dispersion rings around the PLS, area-weighted (override any sector). POD comes from Search Coverage as the teams sweep. After each pass the POA is re-weighted by (1 − POD) — the Bayesian cycle — and the next segments rank themselves.
