Multispectral Image

The process starts with an Orthomosaic image made up of 4 wavelengths Green, Red, Red Edge and Near Infrared (G/R/RE/NIR) plus a 5MP visible light image. Collected by an automated multispectral drone.

These wavelengths are the core four for agriculture and have decades of literature to support their use as the building blocks for vegetative indices.

An aerial view of agricultural fields with varying vegetation, including a large rectangular green field with rows of crops, and surrounding patches of different crop types or land uses.

NDVI Analysis

Software analyses the multispectral data and creates a NDVI (or NDRE) image which displays plant vigor and converts numerical values into a red to green colour map.

What is NDVI?
Aerial view of a grid-based farmland with color-coded sections indicating different crop health levels. Green areas signify healthy crops, yellow indicate moderate health, and red show areas needing attention or with poor health.

Prescription Map

Software analysis can then convert the NDVI data into a prescription map that can be uploaded into an automated spraying drone.

Dosage can be altered accordingly and subdivided into several categories. This image shows 3 prescription areas.
