What is the difference between multispectral and hyperspectral imagery? Normalized Difference Vegetation Index (NDVI) • How NDVI Works • Live green plants absorb solar radiation in the photosynthetically active radiation (PAR) spectral Our kit integrates a High Precision NDVI or NDRE 1. The Normalised Difference Vegetation Index (NDVI) is a measure of the difference in reflectance between these wavelength ranges. When to optimize for memory vs performance speed for a method? Measuring Vegetation (NDVI & EVI) Introduction Normalized Difference Vegetation Index (NDVI) NDVI as an Indicator of Drought Enhanced Vegetation Index (EVI) Consent for your details to be shared. The NDWI products were processed at a spatial resolution of about 463 meters per pixel. ndre vs ndvi
