The project area was approximately 785 square kilometers. The LiDAR was collected and processed to meet the Nominal Post Spacing (NPS)requirement of 1.0 meters. The data was collected using a Leica ALS50-II 150 kHz Multiple Pulses in Air (MPiA) LiDAR sensor installed in a Leica gyro-stabilized PAV30 mount. The ALS50-II 150 kHz sensor collects up to four returns per pulse, as well as intensity data, for the first three returns. If a fourth return was captured, the system does not record an associated intensity value. 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. Part of a project to provide 3D elevation coverage of major cities in the United States.

This dataset was originally collected for NGA by SAIC and Woolpert. After it was released to the public domain, it was made available by the USGS as a Non-Standard Contributed dataset. NOAA obtained the data from USGS and reformatted it for ingestion in the Digital Coast Data Access Viewer. The LiDAR data was acquired with a Leica ALS70 500 kHz Multiple Pulses in Air (MPiA) LiDAR sensor system, on board Cessna 404's. TheLeica ALS70 500 LiDAR system, developed by Leica Geosystems of Heerbrugg, Switzerland, includes the simultaneous first, intermediate and last pulse data capture module, the extended altitude range module, and the target signal intensity capture module. The system software is operated on an OC50 Operation Controller aboard the aircraft. 2012-10-01T00:00:00 1. Resolved kinematic corrections for three subsystems: inertial measurement unit (IMU), sensor orientation information and airborne GPS data. Developed a blending post-processed aircraft position with attitude data using Kalman filtering technology or the smoothed best estimate trajectory (SBET). Software: POSPac Software v. 5.3, POSGNSS Software v. 5.20, IPAS Pro v.1.35. 2. Calculated laser point position by associating the SBET position to each laser point return time, scan angle, intensity, etc. Created raw laser point cloud data for the entire survey in .LAS format. Automated line-to-line calibrations were then performed for system attitude parameters (pitch, roll, heading), mirror flex (scale) and GPS/IMU drift. Software: ALS Post Processing Software v.2.74, Proprietary Software, TerraMatch v. 12.01. 3. Imported processed .LAS point cloud data into project tiles. Resulting data were classified as ground and non-ground points with additional filters created to meet the project classification specifications. Statistical absolute accuracy was assessed via direct comparisons of ground classified points to ground RTK survey data. Based on the statistical analysis, the LiDAR data was then adjusted in relation to the survey ground control. Software: TerraScan v.12.005. 4. The .LAS files were evaluated through a series of QA/QC steps to eliminate remaining artifacts and small undulations from the ground class. Software: TerraScan v.12.005. 2013-01-01T00:00:00 Data was retrieved from USGS on August 2, 2023 in UTM 16N and NAVD88 (Geoid12). Data were converted to geographic NAD83(2011) coordinates and ellipsoid heights in meters for ingestion into the Digital Coast Data Access Viewer. Data were also reformatted into the cloud optimized point cloud version of LAZ format, including using LAS 1.4. 2023-11-07T00:00:00 NOAA Office for Coastal Management (843) 740-1202 coastal.info@noaa.gov processor USGS Non-Standard Contributed Grand Rapids 2012 133 Cities data USGS https://rockyweb.usgs.gov/vdelivery/Datasets/Staged/Elevation/Non_Standard_Contributed/NGA_US_Cities/Grand_Rapids_MI/ WWW:LINK-1.0-http--link Source data Link to the USGS site with the data in UTM 16N. information publisher The dataset has been mosaiced, reprojected, and clipped as needed from the original input files using PDAL and GDAL commands. 2026-06-22NOAA Office for Coastal Managementcoastal.info@noaa.govprocessor
