Landsat 8/9 NDVIc
Normalized Difference Vegetation Index C for Landsat 8/9
Vegetation Satellite Provider: USGS/NASA
Applications
vegetation monitoring with atmospheric correction
improved vegetation assessment
canopy background effect reduction
precision agriculture
vegetation stress detection
Quick Stats
Category: vegetation
Sensor: Landsat 8/9
Provider: USGS/NASA
Bands Used: 3
Description
NDVIc is a corrected version of NDVI that incorporates SWIR bands to account for atmospheric and canopy background effects. The correction factor using SWIR bands helps improve the accuracy of vegetation assessments, particularly in areas with varying atmospheric conditions or soil backgrounds.
