Service Description: Production data were generated using the Normalized Difference Vegetation
Index (NDVI) from the Thematic Mapper Suite from 1984 to 2023 at 250 m resolution.
The NDVI is converted to production estimates using two regression formulas
depending on the level of the NDVI; there is one equation for lower values (and thus
lower production values) and one for higher values. This raster dataset yields
estimates of annual production of rangeland vegetation and should be useful for
understanding trends and variability in forage resources. These results were then
converted to Z-scores for easier comparison of annual relative productivity in
coterminous U.S. rangelands, and for rapid display in online time-enabled
applications.
