Dr. Robert Crippen

Robert E. (Bob) Crippen is an Earth scientist and research geologist in the Solid Earth Science Group at JPL. His work emphasizes new methodologies for information extraction from satellite imagery, currently with emphasis on refining topographic datasets. As a member of the Shuttle Radar Topography Mission (SRTM) and ASTER science teams, he is working to improve Earth's digital elevation model across the entire globe. His previous innovations in image processing include methods to extract sub-pixel measures of ground displacement (e.g. earthquake strains fields and sand dune migration), methods to suppress vegetative, snow, and atmospheric haze features to better reveal the underlying bedrock, and other methods to enhance and extract spectral and topographic information. Dr. Crippen explores new uses of geospatial data to better understand earthquakes, landslides, tsunamis, other natural hazards, and landform and land cover dynamics.
