Geographic Extent: OLC Grass Valley Project Area, covering approximately 228,146 acres. Dataset Description: Quantum Spatial, Inc. (QSI) acquired and processed lidar data describing the Oregon Lidar Consortium's (OLC) Grass Valley Study Area. Lidar data acquisition occurred between April 22 and May 4, 2017. Settings for lidar data capture produced an average resolution of at least 8 points per square meter. The resolution of the DEM is 3 ft. In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEM data were created from, are also available. These data are available for custom download at the link provided in the URL section of this metadata record. purpose: The collection of high resolution geographic data is part of an ongoing pursuit to amass a library of information accessible to government agencies, as well as the general public. credit: Quantum Spatial, Inc. flew the LiDAR and processed the data, Oregon Lidar Consortium (OLC) status: (MD_ProgressCode) completed pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) pointOfContact pointOfContact: (CI_ResponsibleParty) organisationName: NOAA Office for Coastal Management contactInfo: (CI_Contact) phone: (CI_Telephone) voice: (843) 740-1202 address: (CI_Address) deliveryPoint: 2234 South Hobson Ave city: Charleston administrativeArea: SC postalCode: 29405-2413 country: (missing) electronicMailAddress: coastal.info@noaa.gov onlineResource: (CI_OnlineResource) linkage: https://coast.noaa.gov protocol: WWW:LINK-1.0-http--link name: Website description: NOAA Office for Coastal Management Home Page function: (CI_OnLineFunctionCode) information role: (CI_RoleCode) custodian resourceMaintenance: (MD_MaintenanceInformation) maintenanceAndUpdateFrequency: (MD_MaintenanceFrequencyCode) notPlanned graphicOverview: (MD_BrowseGraphic) fileName: https://coast.noaa.gov/htdata/lidar3_z/geoid12b/data/8903/supplemental/or2017_grass_valley_m8903.kmz fileDescription: This graphic displays the footprint for this lidar data set. fileType: KML descriptiveKeywords: (MD_Keywords) keyword: Elevation data keyword: Hydrology keyword: LAS Point Cloud keyword: Lidar keyword: model keyword: remote sensing type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: LiDAR, 3DEP, DEM, Raster, LAS date: (missing) descriptiveKeywords: (MD_Keywords) keyword: beach keyword: DEM keyword: digital elevation model keyword: erosion keyword: laser keyword: lidar keyword: Topography type: (MD_KeywordTypeCode) theme descriptiveKeywords: (MD_Keywords) keyword: Earth Science > Land Surface > Topography > Terrain Elevation type: (MD_KeywordTypeCode) theme thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Science Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: Continent > North America > United States Of America > Oregon keyword: Vertical Location > Land Surface type: (MD_KeywordTypeCode) place thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Location Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: Gilliam County keyword: Grass Valley keyword: Jefferson County keyword: Sherman County keyword: Wasco County type: (MD_KeywordTypeCode) place descriptiveKeywords: (MD_Keywords) keyword: Earth Remote Sensing Instruments > Active Remote Sensing > Profilers/Sounders > Lidar/Laser Sounders > LIDAR > Light Detection and Ranging type: (MD_KeywordTypeCode) instrument thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Instrument Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: Aircraft > Aircraft type: (MD_KeywordTypeCode) platform thesaurusName: (CI_Citation) title: Global Change Master Directory (GCMD) Platform Keywords date: (missing) descriptiveKeywords: (MD_Keywords) keyword: DEMs - partner (no harvest) type: (MD_KeywordTypeCode) project thesaurusName: (CI_Citation) title: InPort date: (inapplicable) resourceConstraints: (MD_Constraints) useLimitation: NOAA provides no warranty, nor accepts any liability occurring from any incomplete, incorrect, or misleading data, or from any incorrect, incomplete, or misleading use of the data.

The statistical model compares known reserved ground survey points (GSPs) to the ground model, triangulated from the neighboring laser points. Vertical accuracy statistical analysis uses ground survey points in open areas where the lidar system has a "very high probability" that the sensor will measure the ground surface at the 95th percentile. For the OLC Grass Valley study area, a total of 1694 ground control points were collected and used for calibration of the lidar data. An additional 121 reserved ground points were collected for independent verification, resulting in a non-vegetated vertical accuracy (NVA) of 0.70 meters, or 0.231 feet. The RMSE is 3.6 cm. result: (missing) lineage: (LI_Lineage) statement: (missing) processStep: (LI_ProcessStep) description: The lidar survey utilized a Leica ALS 80 sensor mounted in a Cessna Grand Caravan. The system settings were developed to yield points with an average native density of greater than 8 pulses per square meter over terrestrial surfaces. The study area was surveyed with opposing flight line side-lap of greater than 60 percent with at least 100 percent overlap to reduce laser shadowing and increase surface laser painting. The system allows up to four range measurements per pulse, and all discernible laser returns were processed for the output data set. processStep: (LI_ProcessStep) description: Ground control points and ground survey points were collected using real time kinematic (RTK), post-processed kinematic (PPK), and fast static (FS) survey techniques. For RTK surveys, a base receiver was positioned at a nearby monument to broadcast a kinematic correction to a roving receiver, for PPK and FS surveys, however, these corrections were post-processed. RTK and PPK surveys recorded observations for a minimum of 5 seconds, while FS surveys recorded observations for up to 15 minutes on each GCP/GSP in order to support longer baselines for post-processing. All GCP and GSP measurements were made during periods with a Position Dilution of Precision (PDOP) no greater than 3.0 and in view of at least 6 satellites for both receivers. Relative errors for the position were required to be less than 1.5 centimeters horizontal and 2.0 centimeters vertical in order to be accepted. In order to facilitate comparisons with high quality lidar data, GCP and GSP measurements were not taken on highly reflective surfaces such as center line stripes of lane markings on roads. GCPs and GSPs were taken no closer than one meter to any nearby terrain breaks such as road edges or drop offs. GCPs and GSPs were collected within as many flight lines as possible: however, the distribution depended on ground access constraints and may not be equitably distributed throughout the study area. processStep: (LI_ProcessStep) description: The NOAA Office for Coastal Management (OCM) received 25 raster DEM files in ESRI ArcGrid format from DOGAMI. The data were in Oregon Lambert NAD83(2011), international feet, coordinates and NAVD88 (Geoid12b) elevations in international feet. The bare earth raster files were at a 3 ft grid spacing. OCM performed the following processing on the data for Digital Coast storage and provisioning purposes: 1. Used internal script to assign the EPSG codes and convert to GeoTiff format. 2.
