It’s All Relative – NDVI That Is. . .
Many of our customers asked for a relative NDVI (Normalized Difference Vegetation Index) scale, and we are pleased to announce it is now available. Relative NDVI displays at a higher contrast, highlighting differences visually far better than true NDVI so you can more easily spot problem areas.
Because relative NDVI makes it easier to spot issues, it is now the default NDVI view, and true NDVI has been renamed NDVI2. Relative NDVI—as its name suggests—is relative to the content of the image, making the colors dynamic, so while you’ll be better able to see issues for a field on a given flight date, relative NDVI images of a field on different dates or even between fields are not directly comparable. To perform a side-by-side comparison of field performance, we recommend switching to true NDVI.
