Introducing the Vegetation Health Index

0

With the growth of precision farming and the proliferation of UAVs and drones, the use of technology in agriculture is increasing rapidly. But how do you make sense of the data that you collect? How do you use it to understand if your crops are truly healthy? For years, scientists have used vegetation health index algorithms like the Normalized Difference Vegetation Index (NDVI) to assess the health of plants. Although it is a relatively simple calculation, knowing what it is and what it does has been difficult for farmers whose expertise is in farming, not data processing.

Now, we introduce the Vegetation Health Index Smart M.App.  This Smart M.App takes the NDVI and makes it accessible to everyone. It allows you to easily measure the density and health of your vegetation.

The Vegetation Health Index Smart M.App works behind the scenes to use values from the red and near-infrared wavelengths to compute the NDVI index, but you don’t need to know that. All you need to do is plug your data in, and it provides a result that can be used to determine crop health. Healthy vegetation areas are quickly identified, allowing you to pinpoint areas that require more attention. The Vegetation Health Index is best if used for large green overlapping foliage that is relatively uniform plant cover as it is sensitive to soil presence.

Features for the Vegetation Health Index include:

  • Minimizes Local Artifacts – Local effects apparent in the raw data such as viewing angle, slope, and shading are minimized by the Vegetation Health Index
  • Color Scheme Selection – Choose a color scheme to yield the best results
  • Wide Range of Sensors Supported – Vegetation Health Index Smart M.App supports a wide range of sensors and file formats

See the Vegetation Health Index Smart M.App in action in this short demo.

The Vegetation Health Index is also available on the M.App Exchange!
