Urbanization and Net Primary Productivity
The top product provides an urbanization map generated from Defense Meteorological Satellite (DMSP) Operational Linescan System data collected from October 1994 to March 1995, showing urban, peri-urban, and non-urban areas. The lower product simulates total annual net primary production for the United States at 1-km spatial resolution. Credit: M.L.
