Web-Enabled Consistent Large Area Landsat Data Streams and Derived Surface Characterizations - a MODIS-Landsat Data Fusion for the Terrestrial User Community
- Visit WELD
The WELD NASA MEaSUREs project contributes to the NASA Land measurement theme; working at high spatial resolution and using state of the art and validated MODIS land products to systematically generate “seamless” consistent 30m Landsat ETM+ mosaics with per-pixel quality assessment information and derived land cover characterization at monthly and longer time periods.
The WELD project will improve the consistency and quality of ETM+ SLC-off data through a fusion with MODIS land products.
The resulting high spatial resolution mosaic products will be generated for the conterminous USA and Alaska for a 7 year period and made freely available to the user community.
The WELD project is a formal collaboration between the United States Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) and its academic partner, the South Dakota State University Geographic Information Science Center of Excellence (GIScCE).
The processing, based on heritage techniques and contemporaneous fusion of MODIS data, is being prototyped at the GIScCE with systematic processing undertaken at EROS. Data products will be updated in near real time and made available to the user community through a modified EROS internet distribution interface.
Preliminary data sets are now available for community assessment and evaluation
