NASA Web-Enabled Landsat Data Alaska 30m Composite Pixel Center Lat/Longs 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 Alaska Latitude/Longitude (LL) product suite. The WELD Alaska LL products are defined with 30 m composite pixel of the center latitude / longitude point. Data Set Characteristics: Image Dimensions: 5000 x 5000 Total Number Tiles: 162 Alaska Tile Volume: 1 GB Compression Type: zip File Format: HDF4, GeoTIFF Map Projection: Albers Equal Area Datum: World Geodetic System 84 (WGS84) Pixel Size: 30 m
  • Version Description
    Initial WELD product suite including CONUS and Alaska at weekly, monthly, seasonal 3 month, and annual time steps.
