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.
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.
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.
