EAARL topography - Vicksburg National Military Park 2008: Bare earth EAARL topography - Vicksburg National Military Park 2008: Bare earth
These remotely sensed, geographically referenced elevation measurements of Lidar-derived bare earth (BE) topography were produced as a collaborative effort between the U.S. Geological Survey (USGS), Florida Integrated Science Center (FISC), St. Petersburg, FL; the National Park Service (NPS), Gulf Coast Network, Lafayette, LA; and the National Aeronautics and Space Administration (NASA)...

EAARL topography: Dry Tortugas National Park EAARL topography: Dry Tortugas National Park
This lidar-derived submarine topography map was produced as a collaborative effort between the U.S. Geological Survey (USGS) Coastal and Marine Geology Program, National Park Service (NPS) South Florida/Caribbean Network Inventory and Monitoring Program, and the National Aeronautics and Space Administration (NASA) Wallops Flight Facility. One objective of this research is to create...

Evaluating a small footprint, waveform-resolving lidar over coastal vegetation communities Evaluating a small footprint, waveform-resolving lidar over coastal vegetation communities
NASA’s Experimental Advanced Airborne Research Lidar (EAARL) is a raster-scanning, waveform-resolving, green-wavelength (532 nm) lidar designed to map near-shore bathymetry, topography, and vegetation structure simultaneously. The EAARL sensor records the time history of the return waveform within a small footprint (20 cm diameter) for each laser pulse, enabling characterization of...

Prospects for quantifying structure, floristic composition and species richness of tropical forests Prospects for quantifying structure, floristic composition and species richness of tropical forests
Airborne spectral and light detection and ranging (lidar) sensors have been used to quantify biophysical characteristics of tropical forests. Lidar sensors have provided high-resolution data on forest height, canopy topography, volume, and gap size; and provided estimates on number of strata in a forest, successional status of forests, and above-ground biomass. Spectral sensors have...

Geologic map and database of the Salem East and Turner 7.5 minute quadrangles, Marion County, Oregon: A digital database Geologic map and database of the Salem East and Turner 7.5 minute quadrangles, Marion County, Oregon: A digital database
The Salem East and Turner 7.5-minute quadrangles are situated in the center of the Willamette Valley near the western margin of the Columbia River Basalt Group (CRBG) distribution. The terrain within the area is of low to moderate relief, ranging from about 150 to almost 1,100-ft elevation. Mill Creek flows northward from the Stayton basin (Turner quadrangle) to the northern Willamette...
