NASA Web-Enabled Landsat Data - Alaska Monthly V015Entry ID: WELDAKMO15
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 Alaska monthly product suite.
The WELD Alaska Monthly products are defined simply with respect to each calendar year by the days in each month.
