Normalized Difference Vegetation Index

The Normalized Difference Vegetation Index (NDVI) is a simple graphical indicator that can be used to analyze remote sensing measurements, typically but not necessarily from a space platform, and assess whether the target being observed contains live green vegetation or not. In simpler terms, and with reference to agriculture, it identifies dry spots in your crops so that you know when and where you may have a problem.

The basic principle of NDVI relies on the fact that leaves, due the their spongy layers found on their backsides, reflect a lot of light in the Near Infrared (NIR), in stark contrast with most non-plant objects. When the plant becomes dehydrated or stressed, the spongy layer collapses and the leaves reflect less NIR light, but the same amount in the visible range. Thus, mathematically combining these two signals can help differentiate plant from non-plant and healthy plant from sickly plant.

NDVI Imagery


The Infrared images produce a unique Color based image of the plant’s health and stress level.

Our NDVI Imagery is a vital tool to ensure precision irrigation and crop management. It makes the invisible visible. It can see things that are hidden to the human eye and can identify parts of the crop that are worthy of closer on-ground inspection. These images can also be used to compare dates to see if problems are address and to track progress.
