Dean Gesch is a Research Physical Scientist with the U.S. Geological Survey at the Earth Resources Observation and Science Center (EROS) in Sioux Falls, South Dakota.
Since 1992, Dean Gesch has worked at USGS/EROS on a variety of geographic science topics, with most related to research and development of topographic data, derivative products, and applications. Most of Gesch’s work has focused on large-area datasets and applications (global, national, regional, and local), and much of the work has been collaborative in nature, working with scientists from other USGS centers and other Federal agencies. He led the design and development of USGS baseline elevation datasets at the national scale (the National Elevation Dataset) and the global scale (GTOPO30 and GMTED2010). His research topics include large-area topographic change analysis and monitoring, hurricane storm surge mapping, elevation data accuracy assessment, and sea-level rise vulnerability assessment. He served as a guest editor for Photogrammetric Engineering and Remote Sensing for a special issue on: The Shuttle Radar Topography Mission – Data Validation and Applications, and was also a guest editor for Journal of Coastal Research for a special issue on: Advances in Topobathymetric Mapping, Models, and Applications. Gesch has served in leadership positions in several national and international forums, including the National Digital Elevation Program, the International Society for Photogrammetry and Remote Sensing Working Group on Global Digital Elevation Model (DEM) Interoperability, and the Group on Earth Observations Global DEM Task. Currently at EROS he is the Principal Investigator leading the Coastal Changes and Impacts focus area in the Integrated Science and Applications Branch.

New land surface digital elevation model covers the Earth
Land surface elevation around the world is reaching new heights—as far as its description and measurement goes. A new global digital elevation model (DEM) is being cited as a significant improvement in the quality of topographic data available for Earth science studies.Land surface elevation is one of the Earth's most fundamental geophysical properties, but the accuracy and detail with which it haAuthorsDean B.

No abstract available.AuthorsD.B. GeschMission in the works promises precise global topographic data
Significant deficiencies in the quality of today's topographic data severely limit scientific applications. Very few available data sets meet the stringent requirements of 10–30 m for global digital topography and 5 m or better vertical accuracy, and existing satellite systems are unlikely to fulfill these requirements.

GeschThe global topography mission gains momentum
An accurate description of the surface elevation of the Earth is of fundamental importance to many branches of Earth science. Continental topographic data are required for studies of hydrology, ecology, glaciology, geomorphology, and atmospheric circulation. For example, in hydrologic and terrestrial ecosystem studies, topography exerts significant control on intercepted solar radiation, water runAuthorsTom Farr, Diane Evans, Howard Zebker, David Harding, Jack Bufton, Timothy Dixon, S.

GeschIdentification of requirements and sources for global digital topographic data
Many of the physical processes being studied by global change researchers are affects by land surface topography and consequently topographic data are an important requirement for these investigations. Remotely sensed data, especially those that will be collected by the instruments of the Earth Observing System, require significant correction to remove topographic effects.
