NASA Web-Enabled Landsat Data CONUS 30m Composite Pixel Center Lat/Longs V001

WELDUSLL.015 was decommissioned on December 2, 2019. Users are encouraged to use the improved monthly and annual Global Web-Enabled Landsat Data (GWELD) Version 3.1 (GWELDMO.031 and GWELDYR.031) datasets and the USGS U.S. Landsat Analysis Ready Data Level-2 Data Product (Landsat ARD). NASA’s Web-Enabled Landsat Data (WELD) are generated from composited 30 meter (m) Landsat Enhanced Thematic Mapper Plus (ETM+) mosaics of the United States and Alaska from 2002 to 2012. These mosaics provide consistent data to derive land cover as well as geophysical and biophysical products for regional assessments of surface dynamics for effective study of Earth system function. The Conterminous (CONUS) United States Latitude/Longitude (WELDUSLL) products provide the geographic latitude and longitude for the center of each 30 meter (m) pixel within a tile of WELD data. WELDUSLL is distributed in Hierarchical Data Format 4 (HDF4) (https://www.hdfgroup.org/products/hdf4/)). The WELD project is funded by the National Aeronautics and Space Administration (NASA) and is a collaboration between the United States Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center and the South Dakota State University (SDSU) Geospatial Sciences Center of Excellence (GSCE).
