🚁 Drone NDVI: Powering Precision AgricultureDrone-based Normalized Difference Vegetation Index (NDVI) is a core technology in GIS Precision Agriculture. It utilizes multispectral cameras (NIR and Red bands) to assess crop health rapidly.The formula, $\text{NDVI} = \frac{\text{NIR} - \text{RED}}{\text{NIR} + \text{RED}}$, quantifies plant vigor, yielding values from -1.0 (non-vegetation) to +1.0 (healthy, dense cover).High spatial resolution drone imagery, processed through GIS software, generates color-coded NDVI maps. These maps enable Variable Rate Application (VRA) prescription files, directing targeted resource application (fertilizer, water) only where needed. This ensures proactive stress detection, optimized inputs, and significant improvements in resource efficiency, sustainability, and yield forecasting
