Port Monitoring compares each new satellite pass of a port with the last one and marks the reclaimed area, berth line and spoil ground that changed.
Your register of berth, reclamation and dredging projects comes mostly from the operator's press releases, annual report and master plan. They tell you what was announced. A site visit tells you what stood there on one day, at one port.
In between, a phase can be reported done while the quay line has not moved, and you find out at the next visit or when the next tender lands. Most ports on your list get no visit in a given quarter.
| Step | Releases and site visits | With Port Monitoring |
|---|---|---|
| Learning that something was built | You read the operator's release or the annual report, and trust the wording. | Each quarter you get the polygons that changed between two passes, whatever the release says. |
| Sizing the reclamation | You take the area from the master plan or the announcement, which is the planned area. | The reclaimed area added since the last pass comes as a polygon you can measure in your own GIS. |
| Following the berth line | A visit, a photo from the quay, or a statement that the extension is open. | The berth line extension shows up on the change layer, with the two images it came from. |
| Watching spoil disposal | Dredging contractors report volumes placed, to whoever asks them. | Growth of the spoil ground, where it shows from above, appears as its own change polygon. |
| Proving it for the register | A note in the register citing a press release, with a date. | A before and after image pair for the pass, dated, that goes straight into the memo or board pack. |
| What the change means | You judge the phase, the delay and the risk from what you know of the project. | You do the same, with the change layer in front of you. |
| Still yours: The phasing call, any completion date, the contract view, and anything that needs a hydrographic or topographic survey. | ||

The two passes behind each change, side by side, so you can see the change for yourself. This is the evidence row in the ledger.

Your first pass sets the baseline. Every later quarter is compared with the one before.

You give us the port or project boundary. We take a high-resolution pass each quarter and compare it with the last clear one. You get the change layer and the image pairs.
The port or project area you want watched, as an outline or a name we can place.
A high-resolution satellite pass over the boundary, RGB, at 0.5 to 2 m.
The new pass is set against the prior one and the changed ground is cut into polygons by type: new fill, quay structure, spoil pile.
The change layer and the before and after pairs reach you, in step with your quarterly review.
History starts when monitoring starts. There is no baseline before it, and we don't reconstruct one.
If the port is under cloud, that pass is skipped and the next clear one becomes the comparison point. A skipped pass is not filled with an estimate.
At 0.5 to 2 m, a pixel is between half a metre and two metres across. New reclaimed ground, a quay line and a spoil heap show. A single bollard, a crane rail or a fine detail of a revetment does not.
It sees what shows from above. Dredging under water leaves no trace in an RGB image, so the dredge footprint and depths are not measured. Spoil ground growth shows only where the material is visible, such as on land or in shallow clear water.
It flags the type of structure that changed. It does not read construction plans or name contractors.
This is an imagery read. It gives no volumes, depths or survey-grade measurements.
It flags the type of change: new fill, quay structure, spoil pile. It does not read construction plans or name the contractor.
No. It is an imagery read of change on the surface. Depths, volumes and anything that needs a survey stay with a surveyor.
That pass is skipped. The next clear pass becomes the comparison point, and nothing is estimated for the gap.
From your first pass. We don't build a baseline from before monitoring starts.
Pick a port where you know the state of the project and start a pilot area there. Compare the layer and the image pairs with your own register entry and what you've seen.
It comes as GeoJSON or a map layer, so it opens in a standard GIS or a dashboard that takes one. We don't write into your register.
The layer is built from satellite imagery of the port you name. Whether you own it or watch it from outside doesn't change what the pass shows.
Ownership and licence terms are agreed in writing when you start. If your legal team needs them earlier, ask.
