Crop health, mapped

NDVI: the earliest honest picture of how a crop is doing.

The Normalized Difference Vegetation Index compares how much red and near-infrared light a canopy reflects. Healthy, chlorophyll-rich leaves absorb red and bounce back near-infrared strongly; stressed or sparse canopy doesn't. That difference is what SaveCrop's multispectral camera captures on every flight.

−1.0 to 0.1 — soil, water, dead cover0.2 – 0.4 — sparse or stressed canopy0.6 – 0.9 — dense, healthy canopy

Why it matters

Stress shows up in reflectance before it shows up in colour

A plant under water, nutrient or pest stress restructures its leaf cells and drops chlorophyll days before a human eye can pick up any yellowing or wilting in the field.

What SaveCrop reads for you

Four readings from one multispectral flight

NDVI
Overall vegetation vigour and density, block by block — the headline health map.
NDRE
Red-edge index, more sensitive in dense mature canopy where plain NDVI starts to saturate.
Thermal delta
Canopy temperature variation, an early tell for water stress ahead of visible wilting.
RGB overlay
A true-colour pass registered to the same grid, so a field team can walk straight to a flagged block.

What you get back

A report built to be acted on, not just filed

01

Block-level heat map

Georeferenced NDVI map with every block scored, exportable as GeoTIFF or PDF.

02

Flagged zones list

Coordinates and area for every block below your chosen health threshold, ranked by severity.

03

Spray-ready file

The same flagged zones exported as a variable-rate prescription, ready for the spraying run.

A stress map is only useful if it reaches the sprayer before the season does — which is why we run survey and spraying as one workflow, not two separate bookings.
