So you want to use your Mavic Pro as an agricultural drone? Sentera has you covered. It has released an upgrade kit for the drone with a NDVI Single Sensor that provides you with visual-band RGB, near-infrared (NIR) and normalized difference vegetation index (NDVI) data. You will be able to use this information to detect problem areas and respond.
Armed with NIR imagery and crop maps, you will be able to make better decisions for your crops.
