Optionally select two single band raster mosaic dataset or image service layers in the table of contents.
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 in the near infrared nir band. This video shows how to generate an ndvi layer in arcgis along with some tips and tricks of working with ndvi layers. The normalized difference vegetation index ndvi is a standardized index allowing you to generate an image displaying greenness also known as relative biomass. The output is added as a temporary layer to the table of contents.
