Lidar data were collected to aid specialized work on the South Napa earthquake including: (1) fault afterslip, especially in the Browns Valley residential neighborhood; (2) shaking and correlation to damage such as red- and yellow-tagged structures, especially in the downtown Napa area; (3) seismic hazards of the West Napa Fault System, especially in residential areas; and (4) geospatial analysis and imagery support (such as post-processing of lidar and other imagery that has already been acquired).</p> <p>Airborne lidar data and imagery were collected on September 9, 2014 as part of multi-agency/institutional response to the August 24, 2014 South Napa Earthquake. Details of the scientific response to this earthquake including the lidar acquisition can be found in Hudnut et al., 2014: <a href='http://pubs.usgs.gov/of/2014/1249/'>USGS Special Open-File Report 2014-1249</a>. Data were collected and initially processed by Towill and are available both as raw files and products as initially delivered by the vendor, as well as the USGS re-processed version of re-classified point clouds and 0.25 meter DEM's from the <a href="http://hddsexplorer.usgs.gov/data/list/disaster/201408_Earthquake_CA/data/AERIAL/NON_INGESTED">USGS HDDS Explorer</a>. Point clouds available from USGS and OpenTopography were reclassified (<a href='https://cloud.sdsc.edu/v1/AUTH_opentopography/www/metadata/USGS/NAPA_2014_metadata.zip'>metadata</a>) by the US Geological Survey; this re-processing was funded by FEMA. Orthoimagery were collected by Towill on September 9, 2014, and by Google on August 24, 2014.</p> Towill, Inc. https://www.towill.com/ originator California Department of Water Resources https://water.ca.gov/ resourceProvider California Geological Survey https://www.conservation.ca.gov/cgs resourceProvider Federal Emergency Management Agency https://www.fema.gov/risk-mapping-assessment-and-planning-risk-map resourceProvider Geotechnical Extreme Events Reconnaissance http://www.geerassociation.org/ resourceProvider Pacific Earthquake Engineering Research Center https://peer.berkeley.edu/ resourceProvider U.S. Geological Survey https://www.usgs.gov/ resourceProvider null info@opentopography.org https://opentopography.org distributor en geoscientificInformation -122.365140468277 -122.246134781087 38.1076886699654 38.3509321917753 https://doi.org/10.5069/G9F769H3 HTTP Standard Internet browser Download Navigate directly to the URL for data access and download.
