Spatial probability for missing-person response

Score where a missing person is most likely to be found. Direct ground teams to the highest-density hexes first.

Predict access and use

Restricted access. Predict is not part of the standard plan. Access is granted by application only, to organisations with appropriate operational expertise. Apply for access.

Decision support only, never a replacement. Predict outputs are probability priors. They must never replace expert human judgment, established response protocols, or any duty-of-care obligation. Outputs may be incorrect, incomplete, or unsuitable for a given scenario. Final decisions sit with qualified human operators.

Predict returns a probability surface across an H3 hex grid, conditioned on behavioural profile, terrain, and weather. Use it to direct ground teams, prioritise patrols, or front-load the highest-density area before searchers arrive.

Inputs: a behavioural profile (despondent, dementia_alzheimers, others), an area (circle, polygon, path), age, datetime, and weather. Output: an H3 grid scored by likelihood. Render in deck.gl, kepler.gl, or QGIS. Pair with get_isochrone for evacuation reach. Pair with reverse_geocode to anchor incident inputs.

Predict carries a Research Preview label because we keep refining the behavioural priors. The model is real, callable, and stable to depend on.

Patterns

What this looks like in practice

Common shapes mapped to the tools you'd reach for.

Trailhead probability surface

Given a despondent profile, a 5km radius from the trailhead, and current conditions, generate the top 50 most likely H3 hexes ranked by score. Direct ground teams to the highest-density area first.

Evacuation reachability

Compute walking isochrones from at-risk locations to model who can get to safety inside 15, 30, or 60 minutes. Combine with predict outputs to prioritise outreach.

Incident-to-coordinates parsing

Run incoming radio reports through parse_address, anchor the result with geocode, and feed the coordinates straight into predict. The agent flow handles 'last seen near the Crown pub on Bridge St' end to end.
