Kern Canyon Lidar Collection, CA 2008
공공데이터포털
Between September 2008 and September 2009, data were collected along the Kern Canyon fault starting south-east of Bakersfield and extending north to the southern end of Kings Canyon National Park. This dataset has helped identify late Quaternary deformation, and other seismogenic processes that are occurring within this section of the Sierra Nevadas. In addition, lidar derived topographic data was used for interpretation, analysis and mapping of floodplains along Isabella Lake, as well as the Kern River and its tributaries. For additional information about this dataset and related geologic investigations, see: C.C. Brossy, K.I. Kelson, C.B. Amos, J.N. Baldwin, B. Kozlowicz, D. Simpson, M.G. Ticci, A.T. Lutz, O.

Terrestrial lidar data of debris-flow sediment in Glenwood Canyon, CO, 2021
공공데이터포털
This release includes lidar point cloud and Wolman pebble count data for a debris-flow deposit in Glenwood Canyon, CO. The data, FullDepositRegion.las (las 1.2), were collected with a terrestrial laser scanner and includes the full deposit and portions of the slope and drainage that generated the debris flow. This .las file includes point cloud data up to 250 m upslope of the deposit, though the data are sparse at distances greater than 60 m from the deposit due to slope geometry and shadowing. The data TrainingRegion.txt includes an 83 m^2 subregion of the .las point cloud that has been manually divided into granular materials >6.3 cm (clast) and <6.3 cm (matrix) in size along the intermediate particle axis. Each particle >6.3 cm in size received an index that was applied to all points belonging to that particle as described in the column header details. The PebbleCount.csv data contains 150 particle size measurements collected at the debris-flow front, obtained with a gravelometer (<18 cm) or measuring tape (>18 cm).
Illilouette Creek Basin Lidar Survey, Yosemite Valley, CA 2018
공공데이터포털
This lidar dataset was collected by NCALM for Sally Thompson at the University of California, Berkeley. This study aims to assess the occurrence and characteristics of post-fire erosion gullies caused by the Empire Fire in Illilouette Creek Basin, California. The study area covers approximately 74 km2 in Yosemite National Park, California.
Jemez River Basin Snow-off Lidar Survey
공공데이터포털
High-resolution Lidar survey covers the area of 722 km2 which includes the Valles Caldera (upper part of the Jemez River basin) and Frijoles Canyon, New Mexico. The data collection was jointly funded by the National Science Foundation (NSF), Valles Caldera National Preserve (VCNP), Bandelier National Monument/National Park Service (BNM/NPS) and United States Geological Survey (USGS) and performed by the National Center for Airborne Laser Mapping (NCALM) during a snow-off season (June and July 2010). The dataset contains point cloud tiles in LAS format, 1 m Digital Surface Model (DSM) derived using first-stop points, 1 m Digital Elevation Model (DEM) derived using ground-class points and 1 m hill shade dataset derived from DEM. This dataset, together with the snow-on Lidar survey performed in March and April 2010, are being used to estimate snowpack, vegetation biomass and distribution, and bare earth elevations to help better understand and quantify ecosystem structure, geomorphology, and landscape processes within the Critical Zone Observatory.
