The Shuttle Radar Topography Mission Digital Elevation Model: A National Resource

Dr. Paul Rosen and Dr. Scott Hensley
Radar Science and Engineering Section (334)


On February 22, 2000, the Shuttle Radar Topography Mission (SRTM) completed an unprecedented 11-day collection of radar data to generate nearly global topographic maps of the earth. This talk will provide a visual tour of some of the spectacular data coming out of this project, and highlight the significant engineering challenges faced in fashioning these data from raw radar bits into the world's most accurate digital elevation model. The SRTM data production facility at JPL was completed in April 2002. Full-scale production began that month, with three continents completed as of September 2002, on schedule. Detailed assessments of the accuracy of these data accompany each continental delivery, and show that the data are of excellent quality, surpassing mission requirements.

The Speaker

Dr. Paul Rosen was the Project Element Manager for SRTM Algorithm Development and Verification. He has also worked extensively in the area of radar imaging geodesy and change detection. His current interests lie in development of dual-use radar technologies and missions.

Dr. Scott Hensley led the SRTM Interferometric Processor Development Team for the processor that converted the SRTM radar data into elevation measurements. His research interest is in applications and algorithm development for radar interferometry. He is the GeoSAR Chief Scientist.
