Enhanced Web Enabled Landsat Data (WELD) Access

The NASA Making Earth System Data Records for Use in Research Environments (MEaSUREs) funded Web-enabled Landsat Data (WELD) project is systematically generating 30m composited Landsat Enhanced Thematic Mapper Plus (ETM+) mosaics of the conterminous United States and Alaska. The WELD project has demonstrated the potential of large volume Landsat data processing to provide, on a systematic basis, continental scale 30m Landsat data products in support of the Landsat user community. Under current MEaSUREs funding we have developed an intuitive what you see is what you get (WYSIWYG) WELD product Internet distribution interface, developed using open source software, and now operational at the USGS EROS with more than 250 registered users (http://weld.cr.usgs.gov/).

This focused, modestly budgeted, two year ACCESS proposal seeks to undertake research to support commonly articulated outstanding user requirements for (1) provision of the WELD products in different map projections, (2) expansion of the WELD product distribution to global scale, (3) support of Open Geospatial Consortium (OGC) compliant WELD products.
