Integrate downstream, never duplicate
Malaysia does not need a private weather service. JPS already publishes Flood Forecast Hazard Management maps, MetMalaysia already runs the radar, NADMA already owns the national coordination. AnBanjir consumes exactly those sources and adds the part nobody owns: the last kilometre — mapping a basin-level warning onto affected streets a council can actually act on, per-responder status boards instead of radio chaos, shelter capacity that updates as families arrive, and a per-household record of what was warned, when, and through which channel.
Every level in the product names its source and its confidence. A red band that came from FFHM says FFHM. A street-level inference from gauge telemetry says inferred — and degrades visibly when the feed goes stale. The honest-state spine again: AnOmbak will not colour a road it has not measured; AnBanjir will not raise a levee marker it has not received.
The rebuild ledger is the product
The flood ends and the harder phase starts: claims, repairs, audits, and the second flood two years later where nobody remembers which drain was cleared. AnBanjir's post-event ledger is append-only — every warning, every deployment, every claim and disbursement a dated, attributable event — so a council can answer the auditor and the resident with the same record. That ledger is also, quietly, the training data: next monsoon, the models that place the risk bands get better precisely because the last monsoon was written down instead of workshopped.
“We are not replacing the disaster agency. We are giving the council the notebook the disaster agency's data deserves.”
