This metadata record describes the Classified Point Cloud (LAS) for the 2016 - 2017 Michigan LiDAR project. The data collection was funded by NRCS and USGS and the State of Michigan was in charge of collection. Thirty counties were collected in total, though not all are available yet. This record will be updated as more counties are added.
The NOAA Office for Coastal Management (OCM) downloaded USGS_LPC_MI_31Co laz files from this USGS site:
ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/Elevation/LPC/Projects/ and processed the data to the Data Access Viewer (DAV) and to https.
Counties included:
Arenac, Barry, Bay, Chippewa, Clinton, Eaton, Gladwin, Hillsdale, Huron, Ingham, Ionia, Iosco, Isabella, Jackson, Kent, Lenawee, Livingston, Macomb, Mason, Midland, Monroe, Oakland, Oceana, Ogemaw, Ottawa, Sanilac, St. Clair, Tuscola, Washtenaw

| Abstract: |
This metadata record describes the Classified Point Cloud (LAS) for the 2016 - 2017 Michigan LiDAR project. The data collection was funded by NRCS and USGS and the State of Michigan was in charge of collection. Thirty counties were collected in total, though not all are available yet. This record will be updated as more counties are added. The NOAA Office for Coastal Management (OCM) downloaded USGS_LPC_MI_31Co laz files from this USGS site: ftp://rockyftp.cr.usgs.gov/vdelivery/Datasets/Staged/Elevation/LPC/Projects/ and processed the data to the Data Access Viewer (DAV) and to https.

Data Quality
| 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.

| Completeness Report: |
LiDAR data is collected for the project area. 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. |
