Introduction to NVDI

This module explores one of FEWS NET's key remote sensing products, the Normalized Difference Vegetation Index (NDVI), and its applications.

After completing this module, you will be able to:

• Define the Normalized Difference Vegetation Index (NDVI)
• Explain the use of maximum value compositing (MVC) to mitigate atmospheric contamination
• Describe the effect of temporal smoothing techniques on image quality
