Lidar intensity data was also collected. 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. Horizontal positions, provided in decimal degrees of latitude and longitude, are referenced to the North American Datum of 1983 (NAD83). Vertical positions are referenced to the NAD83 ellipsoid and provided in meters.

Horizontal Positional Accuracy The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than +/- 0.75m.; Quantitative Value: 0.75 meters, Test that produced the value: 1 Sigma Vertical Positional Accuracy The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than +/- 0.20m.; Quantitative Value: 0.20 meters, Test that produced the value: 1 Sigma Completeness Measure Cloud Cover: Unknown Completeness Report Not provided Conceptual Consistency 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. These data were collected using the CHARTS system. It is owned by the Naval Oceanographic Office and operated through contract. The system collects topographic lidar data at 9kHz, bathymetric lidar data at 1kHz and 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 410 equipment. All raw data streams are transferred to the office for downloading and processing in SHOALS GCS software. Aircraft position data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. Upon inspection and QA/QC in the software packages Fledermaus and PFM_ABE, anomalous data are flagged as invalid. PFM_ABE's chartsLAS module then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID03 model and exports data as a series of first return topography (TF), last return topography (TL) and bathymetry (H) ASCII files. The bathymetry files contain all of the returns from the bathymetric sensor which include returns both above and below the water. The National Geodetic Survey's (NGS) GEOID03 model was used to transform the vertical positions from ellipsoid to orthometric heights referenced to the North American Vertical Datum of 1988 (NAVD88). The 3-D position data were sub-divided into a series of ASCII file products, with each covering approximately 5 kilometers of shoreline. The file index was provided by the shape file, "mi_michigan_boxes.shp", and the numbers used to identify files are in the "Box" field of the shape file. The data file naming convention is based on the year, project, area name, "Box" number and product type (topographic or bathymetric). An example file name is "2008_NCMP_MI_Michigan_07_ASCII", where 2008 is the year of data collection, NCMP is the project under which data were collected, MI_Michigan is the area of data collection, 07 is the "Box" number and ASCII is the product type. The ASCII columns are Longitude, Latitude, UTM Zone, Easting, Northing, Elevation (orthometric), Elevation (ellipsoid), Date, Time, and Intensity. 2009-01-01T00:00:00 The NOAA Office for Coastal Management (OCM) received topo and hydro files in ASCII format. The files contained LiDAR elevation and intensity measurements. The points were classed as 'never classified.' The data were provided in Geographic coordinates and ellipsoidal heights and in orthometric heights. OCM performed the following processing to the ellipsoidal height data to make it available within the Digital Coast: 1. LASEdit was used to convert the ASCII formatted files to las format. 2. The hydro points classification was changed from 'never classified' to class 11, 'bathymetry'. The topo points classification remains as class 0, 'never classified'. 3. The LAS data were sorted by latitude and the headers were updated. 2009-11-01T00:00:00 The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID18) meters, using the GEOID18 grids provided by the National Geodetic Survey. Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (https://rapidlasso.de/laszip/) Processing notes: 2025-07-01T12:08:59 NOAA Office for Coastal Management coastal.info@noaa.gov processor
