Crop vigour and stress mapped from multispectral index processing (NDVI / NDRE) — stress zones that appear before anything is visible to the eye, plus lodging, weed patches, waterlogging and emergence gaps, located, sized and severity-rated, with agronomist follow-up flagged where specialist diagnosis is needed.
MULTISPECTRALEvery 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 | Field 7, southern margin adjacent to hedge line |
| Frame reference | DJI_2031 (thermal + RGB pair) |
| Estimated affected area | Approx. 0.6 ha |
| Confidence | High |
| Severity rating (RAG) | AMBER |
Observation: A distinct cool, wet-looking zone is visible in both thermal and RGB imagery along the field margin, with visibly stunted/discoloured crop within its boundary.
Probable cause: Consistent with poor drainage along this margin, on balance of probability linked to the adjacent hedge line ditch.
Recommended action: Recommend a ground drainage check of this margin ahead of next season's planting.
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.
