How to delineate crops from Drone Orthophotos with QGIS - Tutorial

- While doing research on machine learning algorithms for drone orthophotos we found that crops can be delineated with just standard QGIS with excellent performance. Based on the addition of the blue and red band divided by the green band we can have a new vegetation index where the most healthy crops have low index values (0-1.5) and the dry crops / barren soil have high values (more than 1.9). This tutorial shows the complete procedure on QGIS to perform the delineation from bean plants on a drone orthophoto with a resolution of 5cm.

Nice, I'm going to try this. I haven't come across the Hatari index before. I've had best results with excess green - excess red 3G -2.4R -B though my use case is just distinguishing any plant from bare ground. Your method seems to handle shadows better.
The hatari index was made up from the observations. It works... however we are not clear about the physical background
Excelente aporte! Continúa así! Gracias!
Is it possible to monitor forest loss automatically with QGIS?
Sir please make more vedio on Agriculture
