NDVI & Crop Health Analysis
across Gloucestershire
NDVI (Normalised Difference Vegetation Index) shows how vigorously your crop is growing, metre by metre. Our multispectral drone measures reflected red and near-infrared light and turns it into colour-coded maps that show where a crop is thriving and where it's struggling — often before you can see it from the ground.

Frequently asked questions
What's the difference between NDVI and NDRE?
NDVI uses red light and works well on early and mid-season crops. NDRE uses red-edge light and stays useful later in the season when canopies are dense.
Can the maps go straight into my sprayer or spreader?
We can convert NDVI into prescription zones and export them in common formats for compatible machinery.
