Dr. David Roy, a renowned remote sensing scientist from the South Dakota State University, visited RADI and delivered keynote speech titled "Taking advantage of the moderate resolution data record: consistent global processing of Landsat and Sentinel-2 data and applications" at the 111th Academic Forum of Earth Observation and Digital Earth of RADI on January 27, 2016. Dr. David Roy introduced the Web-Enabled Landsat Data (WELD) project, which is being expanded to global scale to provide monthly and annual Landsat 30m and Sentinel-2 information for any terrestrial non-Antarctic location for six 3-year epochs spaced every 5 years from 1985 to 2010. The WELD products, which are available via the internet for free, are developed specifically to provide consistent data that can be used to derive land cover as well as geophysical and biophysical products for assessment of surface dynamics and to study Earth system functioning.
Dr. David Roy has a Ph.D. from the Department of Geography, Cambridge University U.K. (1994), and his research interests cover the development of remote sensing and advanced computing methods to integrate/fuse satellite sensor data and to map and characterize terrestrial change, Petabyte volume satellite data processing and visualization, and the causes and consequences of land cover and land use change. He is co-chair of the USGS NASA Landsat Science team, a member of the NASA MODIS land science team, the NASA Land-Cover/Land-Use Change Science Team, the NASA Suomi National Polar-orbiting Partnership (NPP) land science team, and the GOFC-GOLD (The Global Observation of Forest and Land Cover Dynamics) Fire Implementation team.
