XENTINEL WATCHTOWER · NEW FEATURE
Maritime and supply chain awareness
Live vessel positions, marine forecasts for 673 ports, and a risk score for 13 strategic passages computed from traffic against each passage's own baseline — read next to the trade and price layers that show what a disruption would touch.

What it is
Indonesia is mostly water, and much of what moves through the country moves by sea. The platform treats maritime traffic as a monitored layer: live vessel positions with name, type, speed, course and destination, alongside the port and waterway reference data that gives those positions meaning.
Passages where traffic concentrates are tracked individually, because a disruption there propagates further and faster than anywhere else. A delay at one strait is felt in ports, prices and schedules across several provinces, which is exactly why it is worth watching on its own.
- Vessel positions — live traffic with identity, type, speed, course and destination.
- Port reference — 673 ports with location, code and province, as the anchor for forecasts and traffic.
- Waterway zones — 375 maritime zones held as boundaries, so geography and responsibility are explicit.
- Passage risk — 13 strategic passages scored individually rather than as one national figure.
- Air traffic — live aircraft positions as the second mode, with trail history for a recent window.

How a passage is scored
Each passage keeps a daily record of vessel counts. The score compares the recent window against that passage's own 30-day baseline — a fall in traffic relative to normal contributes points, and so do an active-conflict signal and a gap in vessel identification coverage. The result is a score on a 0–100 scale with a level, plus the percentage change and how it has moved week over week.
Scoring against a baseline rather than a fixed number is what makes the reading comparable between a busy strait and a quiet one. Each is measured against its own normal, so a quiet passage that halves its traffic is not hidden by a busy one that is simply busy.
- Traffic deviation — the recent window against the 30-day baseline, weighted by how large the departure is.
- Coverage gaps — periods where identification signals are missing, which can mean an outage or deliberate silence.
- Week-over-week change — direction and size, so a slow drift is distinguishable from a step change.
- Vessel counts — the raw number behind the score, visible per passage.
- Per-passage detail — the breakdown in a panel rather than a single number.

Ports, forecasts and briefs
Marine forecasts cover 673 ports with wind, wave, current, tide and visibility on a three-hourly horizon, so a berthing decision and a passage-risk reading can be taken on the same screen. Waterway boundaries are held as reference geometry for the zones traffic passes through.
Passage readings compile into a branded PDF on a daily or weekly cadence, with a risk matrix, the trend and a per-passage section — a brief that can be forwarded as it comes out, without anyone assembling it by hand first. It exists because a risk score that has to be put together manually is a score nobody reads on a busy morning.
A single number is not a warning; the baseline, the change and the coverage quality are what make a passage reading actionable.

The economic edge
Maritime layers are read beside the economic ones: daily food prices by province, trade flows by port and partner, and the live markets panel. When a passage or a port is disturbed, the price and trade layers that would move are already on the map rather than in another system to be found later.
That adjacency is the practical value of one platform. The maritime reading says where something is happening, and the economic layers say what it would touch, in the same view and with the same time filter.
- Food prices — daily commodity prices across 34 provinces, with inflation sub-layers.
- Trade flows — exports and imports by port, partner and value.
- Markets — currency, index and commodity indicators with their recent history.
- Ports and passages — the reference geometry that connects a disruption to the places that feel it.

How it is used
The passage score is a screening tool: it says where to look, and the panel then says why. Traffic against baseline, the coverage picture, news about the area and the ports inside it are all reachable from the same reading.
Because the economic layers sit in the same platform, the next question — what does this cost, and who absorbs it — is answered without leaving the map or waiting for another team's report. The two readings are meant to arrive together, because a disruption is only actionable once its consequences are visible.

Limits and controls
Vessel positions come from signals that ships broadcast, so coverage is good where traffic is dense and thinner where it is not. The score states that honestly by weighting coverage gaps instead of pretending the picture is complete everywhere.
Forecasts are forecasts, and the marine horizon is short by design. The platform shows the window it covers and the time it was computed, so a decision taken on it knows how far ahead it is looking.
