Precision drone farming is one of the techniques that generate the most interest in the industry, for its effectiveness and precision to monitor large field areas.
Drones and their automation together with multispectral and hyperspectral sensors, thermal cameras and spray instruments, are examples of the most used tools for the development of new technologies and agricultural services.
Using drones as monitoring and analysis tools can be very efficient in generating valuable information about crops. First, an orthophoto can be obtained to visually analyze the field with great precision. Also, topographic analyzes such as altimetry, contours and terrain and surface models can be performed.
Through multispectral image processing, color maps with multiple vegetation indices are obtained; depending on the index used (NDVI, NDRE, VARI, OSAVI, etc). Various aspects of crops can be observed, such as: water stress, breathing and chlorophyll, macronutrient levels, pests, relative biomass indices and many other variables of great importance for productive exercise.
As a service, precision agriculture with drones requires direct communication between the agronomist in charge of the crops to be monitored and the service provider; seeking a detailed customization to ensure the objective of granting more intelligence, more control and more efficiency in the productive exercise.
