What is the geo-fencing function?

 

This function is available in the Settings menu of the FreeFlight Pro app and is for setting the maximum flight distance and height.

 

What is the NDVI index?

 

The NDVI index is used throughout the world to monitor drought and control and forecast agricultural production. This index also helps prevent fires and map desertification.

 

The NDVI index is used primarily for the global observation of vegetation because it compensates for changes in lighting conditions, surface gradients, exposure and other exogenous factors.

 

The documented default NDVI equation is as follows: NDVI = ((IR - R)/(IR + R))

IR = pixel values of the infrared spectral band

R = pixel values of the red spectral band

This index generates values between -1.0 and 1.0,

NDVI can quickly provide a status on the agricultural area and highlight hot spots to be studied:

-Crop recognition: quick overview

-Identification of the spread of the disease

-Relative maturity of the crop

-Damage estimation



 

What are the other indices of the Pix4D and Airinov tools for identifying crop health and growth?

 

NDVI (Normalized Difference Vegetation Index): It is used primarily for the global observation of vegetation because it compensates for changes in lighting conditions, surface gradients, exposure and other exogenous factors        

 

GNDVI (Green Normalized Difference Vegetation Index): This vegetation index that provides additional information is commonly used to determine water and nitrogen absorption in cover crops.



NDRE: Very similar to the normalized difference vegetation index (NDVI), it uses the ratio of the near infrared and the red border according to a different mathematical formula as below.
