- 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)
- Vegetation Near Real-Time Data - NASA Earthdata
Vegetation Near Real-Time Data 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
- 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
- MEaSUREs Vegetation Continuous Fields (VCF) Yearly Global 0 . . . - Earthdata
Fractional vegetation cover (FVC) is the ratio of the area of the vertical projection of green vegetation above ground to the total area, capturing the horizontal distribution and density of vegetation on the Earth's surface
- 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
- The Harmonized Landsat Sentinel-2 Project Releases Vegetation Indices
NASA’s Harmonized Landsat and Sentinel-2 (HLS) project released two new products, the Landsat 30-meter Vegetation Index (HLSL30VI) and Sentinel-2 30-meter Vegetation Index (HLSSS30VI) Each product contains a suite of nine vegetation indices including greenness, vegetative moisture content, burned area, and vegetation change (see below for a full list of indices available)
- 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
- Global Vegetation Greenness (NDVI) from AVHRR GIMMS-3G+, 1981-2022
Description This dataset holds the Global Inventory Modeling and Mapping Studies-3rd Generation V1 2 (GIMMS-3G+) data for the Normalized Difference Vegetation Index (NDVI) NDVI was based on corrected and calibrated measurements from Advanced Very High Resolution Radiometer (AVHRR) data with a spatial resolution of 0 0833 degree and global coverage for 1982 to 2022 Maximum NDVI values are
