NASA Web-Enabled Landsat Data CONUS 30m Composites over Monthly Periods V001

Version 001
  • 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) Earth Resources Observation and Science (EROS) Center and the South Dakota State University Geospatial Sciences Center of Excellence (GSCE). WELD systematically generates 30 m composited Landsat Enhanced Thematic Mapper Plus (ETM+) mosaics of the United States and Alaska from 2002 – 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 monthly product suite. The WELD Alaska Monthly products are defined simply with respect to each calendar year by the days in each month. Data Set Characteristics: Image Dimensions: 5000 x 5000 Total Number Tiles: 501 US CONUS Tile Volume: 250 GB Compression Type: zip File Format: HDF4, GeoTIFF Map Projection: Albers Equal Area Datum: World Geodetic System 84 (WGS84) Pixel Size: 30 m
