AVHRR NDVI and Departure from Average GeoTIFFS
Listed in NASA Earthdata CMR
This product is a GeoTIFF image illustrating the Normalized Difference Vegetative Index (NDVI) across the conterminous United States, as well as subsets for the states of North Dakota, South Dakota, Montana, Wyoming, and Idaho.
Description
In order to provide a product that is easily interpreted by our users, the Upper Midwest Aerospace Consortium (UMAC) acquires a weekly NDVI product and a Departure from NDVI average product from the EROS Data Center and converts these products into a GeoTIFF image.
This GeoTIFF image illustrates for the user the relative greenness of an area and the comparison of a particular week's index to the average of that week historically. The values in the image are no longer linked to real data values, but are rather simply color coded for illustrative purposes. The dataset covers the year 2000 with some gaps.
