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 ... Science Daily: Scientists use AI to update data vegetation maps for improved wildfire forecasts A new technique uses artificial intelligence to efficiently update the vegetation maps that are relied on by wildfire computer models to accurately predict fire behavior and spread. A new technique ... Scientists use AI to update data vegetation maps for improved wildfire forecasts pv magazine International: Using drones, satellite and ground data to map vegetation in PV plants

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. Vegetation indices are used to remotely examine vegetation over a given area. One commonly-used index is the Normalized Difference Vegetation Index (NDVI), which uses the difference between near-infrared (NIR) and red reflectance from the Earth's surface, divided by their sum. In healthy photosynthesizing plants, chlorophyll - the main pigment involved in photosynthesis - strongly reflects NIR ...
