- Use Remote Sensing Data to Study Vegetation Dynamics
Overview Remote sensing data can be used to study vegetation dynamics, such as plant healthiness Like all objects, plants have unique spectral characteristics, and this information can be interpreted from remote sensing data to determine a plant’s condition
- Vegetation Near Real-Time Data - NASA Earthdata
Near real-time data provided by NASA's Land, Atmosphere Near real-time Capability for Earth observation (LANCE) can be used to monitor vegetation and crop conditions
- Vegetation Index - NASA Earthdata
Vegetation indices measure the amount of green vegetation over a given area and can be used to assess vegetation health NASA’s Earth-observing satellites collect several different vegetation indices, including Normalized Difference Vegetation Index (NDVI), Enhanced Vegetation Index (EVI), Leaf Area Index (LAI), and Fraction of Photosynthetically Active Radiation (FPAR)
- Normalized Difference Vegetation Index (NDVI) | NASA Earthdata
Vegetation indices measure the amount of green vegetation over a given area and can be used to assess vegetation health A commonly-used vegetation index is the Normalized Difference Vegetation Index (NDVI), which uses the difference between near-infrared (NIR) and red reflectance divided by their sum

Learn how to access and use NASA's Moderate Resolution Imaging Spectroradiometer (MODIS) Vegetation Indices data
- Impacts of the Largest Dam in China on the Local Vegetation Cover . . .
An increase in dense vegetation cover is observed in elevation zones 2 and 3 (175 to 775 meters) The authors attribute the change in vegetation cover type to a possible increase in local atmospheric moisture and resulting precipitation caused by the construction of the Three Gorges Dam and the rising of the Yangtze River
- Enhanced Vegetation Index (EVI) | NASA Earthdata
Definition: Landsat Enhanced Vegetation Index (EVI) is similar to Normalized Difference Vegetation Index (NDVI) and can be used to quantify vegetation greenness However, EVI corrects for some atmospheric conditions and canopy background noise and is more sensitive in areas with dense vegetation
- MODIS Terra Vegetation Continuous Fields Yearly L3 Global . . . - Earthdata
The MOD44B Version 6 Vegetation Continuous Fields (VCF) yearly product is a global representation of surface vegetation cover as gradations of three ground cover components: percent tree cover, percent non-tree cover, and percent non-vegetated (bare)
