Can you explain how NDVI works?
Sure! NDVI stands for Normalized Difference Vegetation Index. It's a remote sensing measurement used to assess vegetation health.
How is NDVI calculated?
NDVI is calculated using the formula: (NIR - Red) / (NIR + Red), where NIR is near-infrared light and Red is visible light.
What do the NDVI values indicate?
NDVI values range from -1 to 1. Values closer to 1 indicate healthy vegetation, while values near 0 suggest barren land.
Can NDVI be used for agriculture?
Absolutely! NDVI helps farmers monitor crop health, optimize irrigation, and manage resources effectively.
