49449 or2012_olc_west_metro_DEM_m8383_metadata Data Set Published / External 49404 DEMs - partner (no harvest) Project Completed 2017-10-15 WSI has collected Light Detection and Ranging (LiDAR) data of the Oregon West Metro Study Area for the Oregon Department of Geology and Mineral Industries (DOGAMI). The Oregon LiDAR Consortium's West Metro project area encompasses approximately 100,000 acres in Washington, Multnomah, and Clackamas County, Oregon. The study area includes the Beaverton, Hillsboro, and Forest Grove metro areas. Data were delivered in: Oregon State Plane North; horizontal and vertical datum: NAD83 (2011)/NAVD88 (Geoid12a); units: International Feet. Between December 28th, 2012 and January 4th, 2013, WSI employed remote-sensing lasers in order to obtain a total area flown of 99,684 acres of which 96,543 acres comprise the area of interest. Settings for LiDAR data capture produced an average resolution of at least eight pulses per square meter. In addition to LiDAR survey, OLC West Metro included high resolution aerial photography was acquired for the entire study area. This metadata was created for the bare earth digital elevation models. Provide high resolution terrain elevation data. 12115 Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > LAND SURFACE > TOPOGRAPHY > TERRAIN ELEVATION > TOPOGRAPHICAL RELIEF MAPS Theme Global Change Master Directory (GCMD) Science Keywords EARTH SCIENCE > OCEANS > COASTAL PROCESSES > COASTAL ELEVATION Theme ISO 19115 Topic Category elevation Spatial Global Change Master Directory (GCMD) Location Keywords CONTINENT > NORTH AMERICA > UNITED STATES OF AMERICA > OREGON Theme Bare earth Theme Bare ground Theme DEM Theme DOGAMI Theme High-resolution Theme Light Detection and Ranging Office for Coastal Management Charleston SC Data Set None Planned Any conclusions drawn from the analysis of this information are not the responsibility of the Oregon Department of Geology and Mineral Industries (DOGAMI), the Office for Coastal Management or its partners.

The data delivered to DOGAMI was found to have a mean vertical offset of -0.033 meters (-0.107 feet) and an RMSE value of 0.051 meters (0.166 ft). Offset values ranged from -0.210 to 0.153 meters For more information about the vertical accuracy, please refer to the final report, listed above in the Supplemental_Information field of this metadata record. ; Quantitative Value: 0.051 meters, Test that produced the value: Tested RMSE in meters in open terrain Lidar data has been collected and processed for all areas within the project study area. Upon receipt from vendor (WSI), all LiDAR data was independently reviewed by staff from the Oregon Department of Geology and Mineral Industries (DOGAMI) to ensure project specifications were met. All data were inventoried for completeness and data were checked for quality, which included examining LiDAR data for errors associated with internal data consistency, model quality, and accuracy. DEM files Organization DOGAMI Originator 1 The LiDAR survey utilized Leica ALS60 sensor mounted in a Cessna Caravan 208B. The systems were programmed to emit either single or multi-laser pulses at a rate of 61.1 or 63.3 Hz, and flown at 900 or 1500 meters above ground level (AGL), capturing a scan angle of +/-30 degrees from nadir. These settings are developed to yield points with an average native density of greater than eight points per square meter over terrestrial surfaces. 2012-01-01T00:00:00 2 The NOAA Office for Coastal Management (OCM) received the files in the proprietary ESRI grid format. The files were converted to floating point GeoTIFF format in vertical meters using gdal_translate from GDAL version 2.1.1. 2017-05-01T00:00:00 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource DEM files 3 Files were converted to cloud optimized geotiff format to support streaming and the vertical units were reverted to feet to match the horizontal units. 2023-08-17T00:00:00 Organization NOAA Office for Coastal Management NOAA/OCM coastal.info@noaa.gov 2234 South Hobson Ave Charleston SC 29405-2413 (843) 740-1202 https://coast.noaa.gov NOAA Office for Coastal Management Home Page Online Resource 49933 Data Set Cross Reference Point cloud used to make this DEM gov.noaa.nmfs.inport:49449 Anne Ball 2017-11-15T15:13:18 Kirk Waters 2024-01-10T18:59:04 2024-01-10 OCM Partners OCMP 1002 Public No No 2022-03-16 1 Year 2023-03-16
