NASA Web-Enabled Landsat Data - CONUS Annual V015Entry ID: WELDUSYR15
Abstract: The Web-Enabled Landsat Data (WELD) project funded by the National Aeronautics and Space Administration (NASA) is a collaboration between the United States Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) and the South Dakota State University Geographic Information Science Center of Excellence (GIScCE).
WELD systematically generates 30m composited Landsat ... Enhanced Thematic Mapper Plus (ETM+) mosaics of the United States and Alaska from 2003 – 2012 to provide consistent data for deriving land cover, geophysical, biophysical products for regional assessments of surface dynamics for effective studying of Earth system functioning.
The Land Processes Distributed Active Archive Center (LP DAAC) is responsible for archive and distribution of NASA WELD, which includes the CONUS annual product suite.
The WELD CONUS Annual products are defined with each year as the preceding year's December through the current year's November.
