WebThe Normalized Difference Vegetation Index (NDVI) is a standardized index allowing you to generate an image displaying greenness (relative biomass). This index takes advantage of the contrast of the characteristics of two bands from a multispectral raster dataset—the chlorophyll pigment absorptions in the red band and the high reflectivity of plant materials … WebNormalized Difference Vegetation Index--0.08: 0.92: 250: 1/250-0.08: TIME_GRID: Time of observation: Minutes since start of synthesis: 0: 18720: 18720: 1: 0: Some specific values are used for the NDVI layer: 251 for missing (bad radiometry), 252 for cloud/shadow pixels, 253 for snow/ice, 254 for sea pixels and 255 for background (missing input ...
