Surface Topography and Vegetation (STV)

STV research areas include bare-surface land topography, ice topography, vegetation structure, and shallow water bathymetry. High-resolution characterization of surface topography would allow for improved understanding of geologic structure, tectonic and volcanic activity, geomorphic processes, sea-level rise and storm surge in coastal areas, glacier and ice sheet mass balance and flow characteristics, and other dynamic processes that could provide new insights into forecasting of natural hazards. In a similar manner, high-resolution characterization of vegetation structure could lead to significant improvement in the understanding of ecosystems, including carbon stocks and fluxes, as well as the relationships between biodiversity and habitat.

Improved measurements of inland and coastal shallow water geomorphology could further inform studies of sea-level change, ice discharge near the grounding line, nautical navigation, and other science and applications objectives at the land-water interface. The team considers improved lidar, radar, and stereoimaging techniques for producing repeat global topography and vegetation structure data products at desired resolutions to meet scientific and application goals.  As a part of that, the team considers the potential benefits of coordinated observing using a mixture of sensors on aerial and satellite platforms along with needed improvements in platform capabilities and information technologies.
