Screenshot

None yet. Requested from incident.archivist@ in addresses.json (capture: yes). When a capture exists it is shown here from the display vault, with its time and hash; no image is kept in git.

What it shows, and how

One "disaster prevention" map application with every layer on the same base map (warnings, typhoon track and probability circle, rain nowcast, river flood and landslide risk meshes), in 15 languages; risk meshes are coloured by what to do, not by millimetres.

Forms: maps, warnings, radar, tracker.

What it does best

Risk coloured by the action it asks for, on one map for every hazard.

What we take from it

One base map for everything; a legend that reads as actions.
