These data are 3D point cloud data collected by laser scanner in the Hetch Hetchy area of Yosemite National Park, USA. The data were collected to assess landscape change and vegetation response following the 2013 Rim wildfire. Filename convention: "hh_datatype_dd_ddmmyyyy_laserreturns_siteidentification". "datatype" is either "alsm" or "tls" The former was collected by the National Center for Airborne Laser Mapping for the U.S. Forest Service and National Park Service, and only a small portion of those data covering this study area are included here. The latter were collected by the U.S. Geological Survey using a Riegl VZ-400 laser scanner. "dd_dd" refers to first and last day of month of data collection. "mmyyyy"...
These data are derived from laser scanning surveys of a paleoseismic investigation site along the north coast section of the San Andreas Fault near Gualala, CA. We performed three surveys with a terrestrial laser scanner at different stages of trench excavation in 2021. To generate more complete maps of the bare ground at the site, we also incorporated airborne laser scanner data from the USGS 3DEP collected in 2018 to fill in gaps and expand the footprints of the digital elevation models. We provide gridded digital elevation models of the combined terrestrial and airborne "bare earth" ground points, the merged terrestrial and airborne point clouds which we used to create these, and the processed airborne and terrestrial...
