The flight day
01 — 06:00
Our pilot sets five RTK-tagged checkpoints around your active area. These are what your engineer will audit the model against.
02 — 06:12
A pre-planned double-grid at 80 m with 75% overlap. Machines keep working — we fly above the exclusion zone, not through it.
03 — 07:30
2,400 frames become a dense point cloud, a triangulated surface, and a 2 cm/px orthomosaic. Checkpoint residuals get reported, not hidden.
04 — 10:15
We difference the new surface against your design or last month's flight and send cut/fill by stockpile and by zone.

Georeferenced 2 cm/px site plan.
Per-pile quantities with basis-of-surface notes.
Heatmap of movement since the previous flight.
Smoothed contours at your chosen interval.
Checkpoint residuals, signed by a licensed surveyor.
Accuracy, stated plainly
A drone survey is only worth what it can be checked against. We withhold two of the five ground checkpoints from processing and report the residuals on both — so the number you get is measured, not marketed.
