50063 usace2007_gl_mi_huron_m550_metadata Data Set Published / External 49401 Lidar - partner (no harvest) Project Completed This is a bare earth data set. The data contained in these files contain hydrographic and topographic data collected by the CHARTS system along the Lake Huron coast of Michigan from August 25 - September 26, 2007. The data were collected and processed in geographic coordinates and ellipsoid heights. The positions were relative to NAD83 in decimal degrees of longitude and latitude. The heights were converted from ellipsoid to orthometric heights (NAVD88) using the Geoid03 model with the results in meters. For data storage and provisioning purposes, the NOAA Office for Coastal Management converted the data from NAVD88 heights to ellipsoid heights using GEOID03. CHARTS integrates topographic and bathymetric lidar sensors, a digital camera, and a hyperspectral scanner on a single remote sensing platform for use in coastal mapping and charting activities. Data coverage generally extends along the coastline from the waterline inland 500 meters (topography) and offshore 1,000 meters or to laser extinction (bathymetry). The topographic lidar sensor has a pulse repetition rate of 9 kHz at 1064 nm (near-infrared wavelength). The bathymetric lidar sensor has a pulse repetition rate of 1 kHz at 532 nm (green wavelength). Native lidar data is not generally in a format accessible to most Geographical Information Systems (GIS). Specialized in-house and commercial software packages are used to process the native lidar data into 3-dimensional positions that can be imported into GIS software for visualization and further analysis.

The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than +/- 0.75 m.; Quantitative Value: 0.75 meters, Test that produced the value: 1 Sigma The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.20 m.; Quantitative Value: 0.20 meters, Test that produced the value: 1 Sigma Not Provided The data provided in this file were tested against ground truth data. At these locations the lidar data matched within 0.20 meters, and different flight line data agreed within 0.20 meters. 1 These data were collected using the CHARTS surveys system. It is owned by the Naval Oceanographic Office and operated through contract. The system collects topographic lidar data at 20 kHz and hydrographic data at 3 kHz. The system also collects RGB imagery at 1Hz. A CASI-1500 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V equipment. Raw data are collected and transferred to the office for downloading and processing in SHOALS GCS software. GPS data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. These data are edited using Fledermaus software where anomalous data are removed from the dataset. The data are converted from ellipsoid to orthometric heights, based on the GEOID03 model, within the chartsLAS program. 2 The NOAA Office for Coastal Management (OCM) received unclassified files in las format. The files contained LiDAR intensity and elevation measurements. OCM performed the following processing on the data for data storage and Digital Coast provisioning: 1. The data were bare-earth classified using MARS Explorer 6.1 software. 2. The data were converted from NAVD88 heights to ellipsoid heights using Geoid03. 3. The LAS header fields were sorted by latitude and updated. 2010-11-01T00:00:00 gov.noaa.nmfs.inport:50063 Anne Ball 2017-11-15T15:24:03 SysAdmin InPortAdmin 2022-08-09T17:11:37 2022-03-16 OCM Partners OCMP 1002 Public No No 2022-03-16 1 Year 2023-03-16
