Measured volumes per pile with surface model imagery — monthly stock reconciliation for quarries, aggregates yards, waste sites and silage clamps, tracked over time.
RECURRINGEvery finding in every report follows the same structure — location, frame reference, affected area, confidence, probable cause and recommended action, rated Red / Amber / Green. Here's a worked (illustrative) example from this survey type.
| Location | Pile B, yard grid reference C4 |
| Frame reference | Surface model, this flight vs previous |
| Estimated affected area | Measured volume: 610 m³ (+140 m³ since last flight) |
| Confidence | High |
| Severity rating (RAG) | GREEN |
Observation: Pile B has increased by approximately 140 m³ since the previous monthly flight, consistent with recorded intake for the period.
Probable cause: N/A — reconciliation finding, not a defect.
Recommended action: No action required; figure provided for stock reconciliation records.
Every finding on every survey type is rated against the same published definitions, so a Red on one job means the same thing as a Red on the next.
