Abstract:

The Web-enabled Landsat Data (WELD) project is collaboration between the United States Geological Survey (USGS) Earth Resources Observation and Science (EROS) Center and academic partner South Dakota State University Geographic Information Science Center of Excellence (GIScCE). It is funded by NASA's Making Earth System Data Records for Use in Research Environments (MEaSUREs), with significant USGS cost sharing. WELD generates 30-meter composites of Landsat 7 Enhanced Thematic Mapper Plus (ETM+) terrain corrected (Level 1T) mosaics at weekly, monthly, seasonal and annual periods for the conterminous United States (CONUS) and Alaska. These mosaics provide consistent data that can be used to derive land cover as well as geo-physical and biophysical products for regional assessment of surface dynamics and to study Earth system functioning. WELD (Version 1.3) monthly, seasonal, and annual products are generated images acquired from December 2007 to November 2008. [Summary provided by the USGS.]

Attribute_Accuracy_Report:

The WELD processing is being prototyped at the GIScCE with planned systematic processing to be undertaken at EROS. The WELD processing is being developed to improve the consistency and quality of Landsat ETM+ data through a fusion with contemporaneous MODIS land products. The WELD data products will be updated in near real time and made available to the user community through a dedicated internet distribution interface. More years of composited mosaic products and future versions with refined processing and content will be provided, most notably atmospheric correction, radiometric/BRDF normalization, cloud and ETM+ SLC-off gap filling, and land cover characterization.
