Greenness of the Conterminous U.S.
Entry ID: USGS_GREENESS

[ Update this Record ]

Summary
Abstract: Since 1989, the USGS EROS Data Center has been mapping the vegetation condition of the conterminous United States (lower 48 states) using satellite information. The vegetation condition maps, or more commonly called "greenness" maps, are produced every week using the latest information on the growth and condition of the vegetation. The greenness maps show the health and vigor of the vegetation.

Project
Quality The Normalized Difference Vegetation Index (NDVI) has been in use for many
years to measure and monitor plant growth (vigor), vegetation cover, and
biomass production from multispectral satellite data. The NDVI image maps shown
here are prepared from 1-km AVHRR spectral data in the visible (Channel 1;
0.58-0.68 micrometers) and near infrared (Channel ... View entire text
