Crisis Map

Incident reports, normalised, geocoded against a local Nominatim and stored as PostGIS geography. One vertical path from a raw record to a point on a map, and one registry from which every surface is generated.

The path

source record
  → normalise      (CrisisMap.Ingest.Normalizer)
  → persist        (CrisisMap.Events, idempotent on external_id)
  → geocode        (CrisisMap.Geocoding, adapter: Nominatim)
  → store position (geography(Point,4326), or NULL with a reason)
  → query          (PostGIS ST_DWithin / ST_Distance)
  → LiveView       (map, list, detail, filters)

Surfaces

11 capabilities are declared once and projected onto each of these. None of them can offer an operation the others do not.

Provenance

Every stored event separates what the source said from what this system worked out. The source fields are normalised, never invented; the derived fields always carry the evidence that produced them, and an unknown position is NULL with a status that says why — never a guessed coordinate.
