Classes 1, 2 and 7 are defined in accordance with the American Society for Photogrammetry and Remote Sensing (ASPRS) classification standards, while class 11 is specific to the NOAA OCM. These data were collected by the Compact Hydrographic Airborne Rapid Total Survey (CHARTS) system along the coast of Michigan and New York. CHARTS integrates topographic and bathymetric lidar sensors, a digital camera and a hyperspectral imager 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). Native lidar data is not generally in a format accessible to most Geographic 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 3-D position data are sub-divided into a series of LAS files, each covering approximately 5 kilometers of shoreline. LiDAR data was collected at a nominal point spacing (NPS) of 2.0 meters. The format of the file is LAS version 1.2. In addition to these lidar point data, the bare earth Digital Elevation Models (DEM) created from the lidar point data are also available. These data are available for custom download at the link provided in the URL section of this metadata record. This data set contains point cloud data(' in LAZ (compressed LAS) format', ''). The data may have been reprojected or otherwise modified from the original data in an automated process. Disregard projection information in this abstract and refer to the spatial reference section. These data were collected as a part of the NCMP to depict the elevations above and below the water in the Michigan and New York Great Lakes coastal zones. completed NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information pointOfContact NOAA Office for Coastal Management (843) 740-1202 2234 South Hobson Ave Charleston SC 29405-2413 coastal.info@noaa.gov https://coast.noaa.gov WWW:LINK-1.0-http--link NOAA Office for Coastal Management Website NOAA Office for Coastal Management Home Page information custodian asNeeded https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid18/1407/supplemental/2011_USACE_NY_MI_GreatLakes_TopoBathy_Lidar_Footprint.kmz This graphic shows the lidar coverage for the Great Lakes regions of New York and Michigan. kmz Compact Hydrographic Airborne Rapid Total Survey (CHARTS) IWG-OCM National Coastal Mapping Program (NCMP) U.S. Army Corps of Engineers (USACE) theme Lidar - partner (no harvest) project InPort otherRestrictions This data set was compiled dynamically.

Completeness Report This data set covers the spatial extent of bathymetric and topographic lidar data obtained during this survey. Conceptual Consistency Differences between a DEM created from the lidar data representing bare ground and the ground truth data is unbiased and within +/- 20 cm (RMSE) in flat terrain and within +/-30 cm (RMSE) in hilly terrain. The USACE collected, processed, and provided the data to the NOAA Office for Coastal Management (OCM). OCM received the data and processed it to be available for custom download from the Data Access Viewer (DAV) and for bulk download from https. 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 10 kHz, bathymetric lidar data at 1 kHz 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 charts2las module then converts all valid data from ellipsoid to orthometric heights based on the NGS' GEOID03 model and exports topographic and bathymetric data as a series of LAS files, one file per flight line. The format of the file is LAS version 1.2. Data are classified as 0 (valid topographic data), 21 (valid topographic data acquired with the bathymetric sensor), 27 (invalid topographic and bathymetric data), 29 (valid bathymetric data). The data are then shifted vertically to the International Great Lakes Datum of 1985 (IGLD85) using the VDatum program from NOAA (National Oceanic and Atmospheric Administration). 2011-12-16T00:00:00 The flightline LAS files are imported into GeoCue V7.0.3.5, which is a geospatial workflow production and management software tool employed by JALBTCX to perform and monitor production of data products. Upon import into GeoCue, the flightline LAS files are divided into a series of boxes, each of which are 1500 meters in length and width. A customized classification macro, built upon the TerraScan V11 module within Microstation V8i, classifies valid topographic data as ground points (2) and unclassified points (1). Upon completion the macro, the classification results undergo quality control and any misclassified points are manually edited. In areas of dense vegetation the bare earth ground points might be incorrectly classified due to the inability of the laser to penetrate the canopy and reach the bare ground. In these areas, JALBTCX defaults to the algorithms ground surface instead of manually reclassifying those points. The final classification results are comprised of individual lidar points with classification s of ground (2) or unclassified (1). They are partitioned into a series of 5km delivery boxes, one Classified LAS file per box. The format of the file is LAS version 1.2. Data are classified as 1 (valid non-ground topographic data), 2 (valid ground topographic data), 21 (valid topographic data acquired with the bathymetric sensor), 27 (invalid topographic and bathymetric data), 29 (valid bathymetric data). 2011-12-19T00:00:00 The NOAA Office for Coastal Management (OCM) received classified topographic files in LAS format. The files contained lidar elevation measurements. The data were received in North American Datum 1983 (NAD83) geographic coordinates and were vertically referenced to NAVD88 using the Geoid09 model. The vertical units of the data were meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The topographic las files were converted from orthometric (NAVD88) heights to GRS80 ellipsoidal heights using Geoid09. 2. Points in class 29 (valid bathymetric data) were reclassified to class 11 (valid bathymetric data) using las2las software. 2012-11-01T00:00:00 Office for Coastal Management processor USACE JALBTCX USACE JALBTCX originator The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. 2026-04-15NOAA Office for Coastal Managementcoastal.info@noaa.govprocessor
