Prototyping Global Web Enabled Landsat Data (WELD) Product Access via the Internet

The NASA funded Web-enabled Landsat Data (WELD) project has demonstrated the potential of large volume Landsat data processing to provide continental scale 30m Landsat data products in support of the Landsat user community. An intuitive what you see is what you get (WYSIWYG) WELD product Internet distribution interface has been developed using various open source software and has been operational at the United States Geological Survey (USGS) Center for Earth Resources Observation and Science (EROS) since October 2010 with more than 700 registered users from more than 28 countries (http://weld.cr.usgs.gov/). New NASA Advancing Collaborative Connections for Earth System Science (ACCESS) funding has been obtained to undertake research to support commonly articulated user requirements for provision of global coverage WELD products and products defined in different map projections. This poster illustrates prototyping of the new Global WYSIWYG WELD product internet distribution interface with on demand reprojection capabilities. Prototype global WELD products are generated in tiles nested to the MODIS land sinusoidal projection. The potential for distribution and integration of WELD 30m products and gridded MODIS land products is illustrated and discussed.
