Abstract: |
Geographic Extent: Waushara County, Wisconsin covering approximately 647 square miles.
Dataset Description of Original Data: Waushara County, Wisconsin 2017 QL2 LiDAR project required planning and acquisition of LiDAR data collected with a point density of 2 pulses per meter with at a nominal point spacing of 0.71 meters. Project specifications were based on the U.S. Geological Survey National Geospatial Program Base LIDAR Specification, Version 1.2. The data was developed based on a horizontal projection/datum of NAD83 (2011) State Plane, Wisconsin South, US survey feet and vertical datum of NAVD1988 (GEOID12B), US survey feet. LiDAR data was delivered as 35 calibrated and controlled RAW flight line swaths, processed to create 760 Classified LAS 1.4 files formatted to individual 5000 x 5000-foot tiles, corresponding 2.0-ft hydro-flattened bare-earth DEMs tiled to the same 5000 x 5000-foot schema in ERDAS .IMG format, and hydro-flattened feature breaklines in Esri polygonZ shapefile and polygonZ file geodatabase feature class format. Ground Conditions: LiDAR was collected in 3 lifts spanning 2 days in the Fall of 2017, with no snow, water at normal levels without unusual inundation, and leaf off conditions. In order to post process the LiDAR data to meet task order specifications, 20 surveyed control points were used to calibrate the LIDAR to known ground locations established throughout the project area. The accuracy of the data was checked with a total of 70 surveyed QC check points. This metadata record supports the data entry in the NOAA Digital Coast Data Access Viewer (DAV). For this data set, the DAV is leveraging the Entwine Point Tiles (EPT) hosted by USGS on Amazon Web Services. |
Purpose: |
Classified LAS files are used to show the manually reviewed bare earth surface. This allows the user to create Breaklines and Raster DEMs. The purpose of these LiDAR data was to produce high accuracy 3D hydro-flattened Digital Elevation Model (DEM) with a 2-ft cell size. The data will be used by FEMA for flood-plain mapping. These raw lidar point cloud data were used to create classified lidar LAS files, 3D breaklines, and hydro-flattened DEMs as necessary. |

Description: |
Entwine Point Tile (EPT) is a simple and flexible octree-based storage format for point cloud data. The data is organized in such a way that the data can be reasonably streamed over the internet, pulling only the points you need. EPT files can be queried to return a subset of the points that give you a representation of the area. As you zoom further in, you are requesting higher and higher densities. A dataset in EPT will contain a lot of files, however, the ept.json file describes all the rest. The EPT file can be used in Potree and QGIS to view the point cloud. |

Data Quality
Vertical Positional Accuracy: |
The specifications require that only Non-vegetated Vertical Accuracy (NVA) can be computed for raw lidar point cloud swath files. The vertical accuracy was tested with 40 independent surveys located in open terrain. 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 project. Specifications for this project require that the NVA be 19.6 cm or better AccuracyZ at 95 percent confidence level. The NVA was tested using 40 independent surveys located in open terrain. The survey check points were distributed throughout the project. The 40 independent check points were surveyed using the closed level loop technique. Elevations from the unclassified lidar surface were measured for the x,y location of each check point. Elevations interpolated from the unclassified lidar surface were then compared to the elevation values of the surveyed control. The RMSE was computed to be 0.048 meters and AccuracyZ to be 0.094 meters. AccuracyZ has been tested to meet the required AccuracyZ value of 19.6 cm for Non-Vegetated Vertical Accuracy at 95 Percent confidence level using RMSE(z) x 1.9600 as defined by the National Standards for Spatial Data Accuracy (NSSDA); assessed and reported using National Digital Elevation Program (NDEP)/ASRPS Guidelines. |
---|---|
Completeness Report: |
These classified LAS data files include all data points collected. No points have been removed or excluded. A visual qualitative assessment was performed to ensure data completeness. No void areas or missing data exist. The classified point cloud is of good quality and data passes Non-vegetated Vertical Accuracy (NVA) specifications. Datasets contain complete coverage of tiles over the project area. |
Conceptual Consistency: |
Data cover the entire area specified for this project. |

Process Steps
Process Step 1
Description: |
Classified LAS Processing: Final lidar LAS delivery classes for the fully classed LAS tiles consistent with ASPRS LAS classes to be compliant with USGS LiDAR Guidelines and Base Specifications v1.2 consist of: Class 1 - Unclassified; Class 2 - Ground; Class 7 â Low Noise; Class 9 - Water; Class 10 - Ignored Ground (including 3-foot buffer around water breaklines); Class 17 - Bridge; and Class 18 - High Noise. Once the analyst was comfortable with the ground macro results, the ground classification QC began using TerraScan. During the QC phase, analysts reclassified the point cloud in areas where the macro was not able to, or created misclassifications. The same rigorous quality steps were performed on each classification. Data were then distributed as virtual tiles to experienced lidar analysts for localized automatic classification, manual editing, and peer-based QC checks. Supervisory QC monitoring of work in progress and completed editing ensured consistency of classification character and adherence to project requirements across the entire project. Upon completion of point classification, an automated process was executed to turn any points to class 1 in the Fully Classified LAS files and to delete all points that fell outside of the provided project buffered boundary. |

Process Step 2
Description: |
Original point clouds in LAS/LAZ format were restructured as Entwine Point Tiles and stored on Amazon Web Services. The data were re-projected horizontally to WGS84 web mercator (EPSG 3857) and no changes were made to the vertical (NAVD88 Geoid12b, US survey feet). |

Process Step 3
Description: |
The NOAA Office for Coastal Management (OCM) created references to the Entwine Point Tiles (EPT) that were ingested into the NOAA Digital Coast Data Access Viewer (DAV). No changes were made to the data. The DAV will access the point cloud as it resides on Amazon Web Services (AWS) under the usgs-lidar-public container.
