Data available by county. Data for all counties are in folders that begin with USGS_LPC_MI_31Co. There is additional laz data in the folder that is titled MI_31County_2016_A16. download dataset Horizontal Positional Accuracy Horizontal positional accuracy is dependent upon the quality of the GPS/INS solution, sensor calibration and ground conditions at the time of data capture. The standard system results for horizontal accuracy meet or exceed the project specified 1.0 meter RMSE. This value is computed by comparing ground control to a DEM derived from the classified LiDAR data and represents the RMSE of residuals on controls within the project area. Vertical Positional Accuracy For the DEM data derived from the classified point cloud, the NVA and VVA were computed. The vertical accuracy was tested with independent survey check points located in various terrain types within the project area. These check points were not used in the calibration or post processing of the lidar point cloud data. The survey check points were distributed throughout the block area. Specifications for this project require that the NVA be 19.6 cm or better @ 95 percent confidence level and the VVA to be 30.0 cm or better at the 95th percentile. Raw NVA was tested using a number of independent survey check points located in flat terrain types. The NVA was tested using a number of independent survey check points located in bare earth terrain types.The VVA was tested using a number of independent survey check points located in various vegetation terrain types. The survey checkpoints were distributed throughout the block area. The independent check points were surveyed using static GPS base stations collecting point location for 20 minute intervals. Elevations were measured for the x,y,z location of each check point. Elevations interpolated from the DEM surface were then compared to the elevation values of the surveyed control. These values are provided as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASPRS Guidelines.

Post processing of the simultaneously acquired GPS/INS is performed and applied to the laser returns to output a point cloud in the specified project coordinate system and datums. The point cloud data is then subjected to automated classification routines to assign all points in the point cloud to ground, water, overlap and unclassified point classes. Anomalous laser returns that occur infrequently are removed entirely from the data set. Once clean bare earth points are established, DEMs are created using bare earth points and hydro features. The DEM surface is then compared to the survey checkpoints. These accuracies must pass the Non-Vegetated and Vegetated Vertical Accuracy specifications. Conceptual Consistency LiDAR data is collected within the project area and processed. After the DEMs were created, the dataset was verified against control. Lidar data were collected via an airborne platform and lidar sensor. They were then processed to a classified point cloud. At selected locations throughout the site, accurate GPS coordinates and elevations are surveyed and the points are marked with targets. 2017-01-01T00:00:00 New LiDAR data is captured for the project area using a Leica ALS70 LiDAR instrument an integrated IPAS20 GPS/INS system mounted within a Aero Commander twin engine airplane. 2017-01-01T00:00:00 The airborne GPS data is post-processed in Inertial Explorer software and LEICA CloudPro software to determine the LiDAR sensor's angle and orientation in the terrain (project) coordinate system and datums during the survey. 2017-01-01T00:00:00 The post processed GPS/INS solution is applied to the raw lidar data to orient and project the data points into the project area reference system as an unclassified point cloud. 2017-01-01T00:00:00 The georeferenced lidar data is then classified and edited in Terrasolid Terrascan software. Data is classified to produce: Class 1: unclassified, Class 2: ground, Class 7: low point, Class 9: water, Class 10: ignored ground, Class 11: withheld. 2017-01-01T00:00:00 The classified lidar data is exported as 2500 X 2500 foot tiles in the LAS format with any or all classes required to produce derivative products. 2017-01-01T00:00:00 Data for Oceana County were downloaded from the USGS Rocky ftp site in NAD83(2011) Michigan South State Plane (ft) coordinates with vertical feet NAVD88 (Geoid12b).

The observed classes fit the USGS LBS 1.2 with 1 = unclassified, 2 = ground, 7 = low noise, 9 = water, 10 = ignored ground near breakline, 17 = bridge deck, 18 = high noise 2022-04-07T00:00:00 Office for Coastal Management processor Source Contribution: The classified lidar point cloud is used to derive various data products such as, but not limited to, bare earth gridded DEM, triangulated irregular networks (TIN), contours, digital surface models (DSM). The output format is fully compliant LAS v1.4, Point Record Format 6 1200 Classified lidar Sanborn Map Company Inc. originator 2017 Source Contribution: Targeted ground control is used to create a digital control file and control report as well as QC check of LiDAR accuracy. Predefined points (NGS when available) within the project area are targeted. Ground control 2010-01-01 publication Sanborn Map Company Inc. originator 2017 Source Contribution: Aerial LiDAR and GPS/IMU data are recorded for the defined project area at an altitude, flight speed, scanner swath width and scanner pulse frequency to achieve the design goals of the project. LiDAR Data Sanborn Map Company Inc. originator 2017 Source Contribution: Post processed GPS/INS is applied to the lidar point data to georeference each point in the project coordinate system 1200 Post processed GPS/INS Sanborn Map Company Inc. originator 2017 Source Contribution: The post processed lidar data has been projected and oriented in the specified coordinate system as an un-classified point cloud. 1200 Post processed lidar Sanborn Map Company Inc. originator 2017 Source Contribution: The tile definition defines discreet non-overlapping rectangular areas used as cut lines to break up the large classified lidar dataset into smaller, more manageable data tiles. Each tile is 2500ft by 2500ft in dimension. 1200 Tile Definition State of Michigan originator 2017 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
