Brown Bag Seminar: Samuel Goward and Darrel Williams

University of Maryland; Global Science And Technology


Over a decade ago the Landsat Legacy team was formed to capture the technical history of the Landsat program before it was lost to retirements, death and document disposal. As a result of the Congressional 1992 Land Remote Sensing Policy Act, a national archive was established at the US Geological Survey EROS Center; the National Satellite Land Remote Sensing Data Archive (NSLRSDA). A first look at the NSLRSDA Landsat holdings raised many questions concerning acquisition variations from year to year.

With funding from the NASA History office and additional support from the Landsat Project Science Office, Drs. Goward and Williams developed the Landsat Legacy team to research and compile this technical history. Over the last decade, this team has conducted extensive activities including document retrieval and recorded interviews, to document the first fifty years of the Landsat program. A manuscript is nearing completion, to be published by the American Society of Photogrammetry and Remote Sensing (ASPRS), which details this technical Landsat history. This presentation will take a quick look at the content of this history.

About the Speakers:  

Dr. Samuel Goward (University of Maryland, Emeritus) has pursued biophysical applications of land remote sensing data since the 1970's, focused on applications of both AVHRR and Landsat.  He served as Team Leader for the Landsat-7 Science Team, and was a member of the Landsat-8 Science Team.  He has served as Chair of the Department of Geographical Sciences at University of Maryland, and has received the USGS John Wesley Powell award, the USGS/NASA William T. Pecora award, and the ASPRS SAIC Estes Teaching award.  

Dr. Darrel Williams is Chief Scientist with Global Science and Technology (GST).  Prior to joining GST, Dr. Williams worked at NASA GSFC for 35 years, including serving as Head of the Biospheric Sciences Branch, and as Hydrosphere-Biosphere Laboratory Associate and Acting Chief.  He also served as Project Scientist for Landsat-7, and Deputy Project Scientist for Landsat-5.  In 1999, Dr. Williams received the Aviation Week and Space Technology Laurels Award in recognitiion of his role on Landsat-7.
