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

Metadata Updated: March 23, 2019

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 seasonal product suite.

The WELD CONUS Seasonal products are defined Winter: December, January, February; Spring: March, April, May; Summer: June, July, August; Autumn: September, October, November.

Data Set Characteristics: Image Dimensions: 5000 x 5000 Total Number Tiles: 501 US CONUS Tile Volume: 170 GB Compression Type: zip File Format: HDF4, GeoTIFF Map Projection: Albers Equal Area Datum: World Geodetic System 84 (WGS84) Pixel Size: 30 m
