Count Component Title Abstract
1 2005 Puget Sound LiDAR Consortium (PSLC) Topographic LiDAR: Lower Columbia River Terrapoint, on behalf of multiple agencies, collected topographic lidar of the Lower Columbia River area. Field data collection took place between the dates of January 10th and February 20th, 2005. The control network and checkpoint surveys were performed from January 4th to February 12th, 2005. The project area covers approximately 890 square miles along the Columbia River, from the Bonneville Dam to the Pacific Ocean. A total of 431 flightlines were required to cover the project area flightlines. Terrapoint used a 40 kHz Airborne Laser Terrain Mapping System ALTMS sensor attached to a Navajo Twin-engin aircraft (C-FVZM). The mission was flown at 3500 feet above ground level at an average speed of 140 knots. The system consists of a 36 degree full scan angle laser, a Trimble 4700 GPS receiver and a Honeywell H764 IMU unit. The nominal flightline spacing was 1070 feet with 30 to 50% sidelap. The surveyed and processed data was received divided by funding agency. The agency responsible for funding each tile is represented as a number (0:COE, 1:DNR, 2:DOGAMI, 3:DOI) in the "User Data" field of each LAS file.

        Count Component Use Limitation
        1 Lidar Use Limitation These data depict the elevations at the time of the survey and are only accurate for that time. Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions. Users should not use this data for critical applications without a full awareness of its limitations. Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data are NOT to be used for navigational purposes.

        1 2005-01-01T00:00:00 The following software was used to reduce the GPS kinematic data, compute the 3-D laser points, classify and edit laser points, produce shaded relief images and transform the ellipsoidal heights to Orthometric: ArcView, Flykin, Microstation, TerraScan, TerraModeler, TerraModel, and Terrapoint Proprietary LiDAR processing software
        1 2013-08-01T00:00:00 The NOAA Coastal Services Center (CSC) received topographic files in ASCII .TXT format. The files contained lidar elevation measurements, GPS time measurements (week/second), number of returns, return number, scan angle, intensity, and classification. The data were received in Washington State Plane South Zone 4602, NAD83 coordinates and were vertically referenced to NAVD88 using the Geoid03 model. The vertical units of the data were feet. CSC performed the following processing for data storage and Digital Coast provisioning purposes: 1. The ASCII .TXT files were run through a parser to convert GPS Week/Second Time to Adjusted Standard GPS Time and change the format of the Classification field. 2. The parsed ASCII .TXT files were converted to LAS version 1.2 using LAStools' txt2las tool. 3. The User Data field was set depending on agency which funded the tile. The User Data values are: 0 (USACE), 1 (DNR), 2 (DOGAMI), 3 (DOI). 4. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid03. 5. The topographic las files were converted from a Projected Coordinate System (WA SP South) to a Geographic Coordinate system (NAD 83). 6. The topographic las files' vertical units were converted from feet to meters. 7. The topographic las files' horizontal units were converted from feet to decimal degrees. 8. The data were converted to LAZ format.
        1 2013-10-17T00:00:00 The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format. The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights.
