Four quarries measured from space every month, within 7% on volume of a ground survey.
Stockpile and digging figures came from drone surveys costing a few thousand dollars each, once or twice a year. In between, nobody could check a contractor's bill.
Where it saves money.
Monthly figures without paying for a drone survey every month, and every digging bill checked before it is paid.
Blind between surveys.
Every figure was as old as the last drone survey. Digging bills were paid on the contractor's word.
The satellite measures. The drone checks it.
Satellite images of all four quarries, every month.
One drone survey lines the model up with the ground.
A survey crew measured a pile by hand, and we published the difference.

The contractor's number, with ours beside it.
Stockpile volumes whenever they need them. A map of what was dug, next to each bill. Slopes steeper than 45° flagged for inspection.

How it runs on site.
Checked on the ground
| Dimension | Surveyed | From satellite | Error |
|---|---|---|---|
| Length | 9.56 m | 9.70 m | 1.5% |
| Width | 6.10 m | 5.73 m | 6.1% |
| Height | 4.50 m | 4.00 m | 12% |
Height is the hardest to measure from above, but it barely affects volume, which sits in the broad base of a pile.

Ten safety rules on the cameras already on the ceiling. Every close call recorded.
Every part tracked from station to station, so nothing goes missing unnoticed.
Oil on the water spotted by the cameras already pointed at it.
