Examples of Vegetation Indices (Work in Progress)

The selection of sensors (link) depends on your objectives. I.e., what do you wish to know from the image? Is it a stress level? If so, what type of stress? Below are some common examples of vegetative indices used to monitor crop health. Vegetation indices are crucial for assessing the health and growth of vegetation.

Precision Hawk:  Precision Analytics: Agriculture

Precision Analytics: Agriculture is a complete Mapping and Analytics web-based platform for precision agriculture crop data management that uses images captured from drone flights. The process for using this web-based portal goes as follows: Collect the image data with your drone and upload the data to your account where you can generate deliverables such as:

NDVI Map

NDVI (Normalized Difference Vegetation Index) is a graphical display that represents the results from images that were captured with a multispectral sensor during a remote unmanned vehicle survey mission and analyzed for the presence of live green plant life. Thus, NDVI information will bear out a measure for crop health. Learn More (Last Edit: 18

SlantRange 3P Multipsectral Sensor

The 3P Sensor collects images needed to create NDVI crop mapping reports. It can calibrate the ambient light in order to distinguish between haze and clouds as well as gauge the time of day and the season. The features for the 3P sensor include: The Price is  (w/ DJI SkyPort) $5,250.00 – As of 21

SlantRange 4P and 4P+ Multispectral Sensors

These sensors measure light from six bands of the light spectrum. The spectral bands measured include RGB imaging plus red, green, red edge, and near-infrared (NIR). Images from the red edge light range of the spectrum allow one to determine the early onset of crop disease and crop stress and are used for both NDVI

Sentera: Scouting Package

This package pairs DJI Phantom 4 Pro drone with Sentera Double 4K Sensors that let you gather NDVI (normalized difference vegetation index) and NDRE (normalized difference red edge) images that you can plug in to analysis, and map, to determine the status of your crop’s health. Use cases include: Stand counts, tassel counts, crop health

Sentera NDVI Upgrade for DJI Drones

With the Sentera NDVI Upgrade the camera is able to capture images with sensors capable of recording the reflected light off the images across the light spectrum: RGB, Mutispectral and Thermal. RGB cameras, RGB (visual color) is the most common type of data collected and the cameras that are typically standard on most commercial drones.

Parrot Bluegrass Fields Agricultural Quadcopter

It has two embedded cameras. In the front, you have a Full HD video camera and a RGB and multispectral sensor, Parrot Sequoia (See image of sensor below). There is also a sunshine sensor that collects and stores the current environmental light details for the surveyed area. It uses a cloud platform for processing data,
