Quay walls, yards and dredge volumes surveyed without stopping operations. Nine berths stay working, the yard is counted twice a day between vessel windows, and the dredge line is held at −16.5 m CD while the cranes keep moving.

The sheet above is a drawing of this. 11 capture waypoints, and every finding called as the aircraft reaches it — scroll sets the target, the mission keeps its own pace, and the page waits for it.
Sector · Ports
Ninety minutes between two ships, and twenty-one of them used. The sortie comes in over the pocket and sounds it against the −16.5 m design line, runs the ship's side while a gantry takes a box off her deck, counts ten blocks of the yard, meets the next arrival under her tugs — then the record goes to the operator on the apron, under the crane, reading the fender, the rail and the bollard nobody would climb down to see.
The dredger claims 48,000 m³ off berth 4. Confirming it means a survey vessel in the box, which means the berth is closed, which means the ship goes to the next port.
The dredger's soundings, the survey vessel's runs and the shore-side flights land on one surface. Difference it against the −16.5 m CD design line and the volume moved, the high spots left and the overdredge read off by berth.
A container yard is a stockpile that argues back. The stack plan says row 14 is clear, the reefer plugs say otherwise, and the shunt driver finds out at 03:00.
Two flights a day return the yard as a surface and a count — stack heights by row, occupancy by block, and project-cargo laydown tied to the same map the terminal plan already sits on.
Under the deck of berth 6 there are 180 piles, a fender line and a service gallery. It gets inspected once something is already broken, by people who have to get down there to look.
A ground unit runs the gallery and the deck underside on a saved route each quarter, returning 360 imagery at the same stations, so spalling and corrosion arrive as a trend line rather than a discovery.

Full yard captures flown between vessel windows
Every instrument on this list flies, floats or walks inside a window the terminal already has. Nine berths stay in service the whole time; the record is what comes out of the gaps.
2×/day, in the gap between box moves
The yard and apron go from berth-clear to flown in 21 minutes of a 90-minute gap. Each flight returns a surface and a count — stack heights by row, occupancy by block, laydown on the terminal plan.
YARD 2×/DAY · BLOCKS 22 · 1.2CMEach high water, over the pocket
The dredger's soundings, the survey vessel's runs and the shore-side flights land on one surface of the basin, so the berth pocket is never argued from three different datasets.
HW 04:12 · POCKET · ONE SURFACEAfter every sounding run, before the dredger moves
The basin surface is differenced against the −16.5 m CD design line: volume moved, high spots left and overdredge read off by berth. The high spot 0.4 m proud at berth 4 re-tasked the dredger, not the berth.

A ground unit runs the service gallery and the deck underside, returning 360 imagery at the same stations every quarter — so spalling and corrosion arrive as a trend line rather than a discovery.

SEQUENCE
The pocket at berth 4 carries a high spot 0.4 m proud of CD −16.5 m — the dredger is re-tasked to it this morning and the berth stays on the sailing schedule; the rest of the box proved clear at 04:12.

The dredger's 48,000 m³ claim reads against the design line before it is paid — volume moved and overdredge split out by berth, off the same surface the terminal already trusts.
