The Reworked Vegetation Index (TVI) is a mathematical expression utilized to remotely sensed knowledge to quantify vegetation greenness. It leverages the differential reflectance properties of vegetation in numerous parts of the electromagnetic spectrum, sometimes pink and near-infrared wavelengths. A raster calculator, discovered in lots of Geographic Data Programs (GIS) and distant sensing software program packages, facilitates the appliance of this formulation to satellite tv for pc imagery, comparable to that acquired by the Sentinel-2 mission.
Using vegetation indices derived from satellite tv for pc knowledge gives an environment friendly methodology for monitoring vegetation well being and dynamics over giant areas. Evaluation of spatial and temporal modifications in vegetation cowl is essential for functions comparable to precision agriculture, environmental monitoring, and land administration. Sentinel-2’s excessive spatial decision and multi-spectral capabilities present worthwhile knowledge for these endeavors, permitting for detailed calculations and visualizations of vegetation indices just like the TVI.
