Abstract

Product: Processed, classified lidar point cloud data tiles in LAS 1.4 format.

Geographic Extent: Approximately 12,101 square miles in southern Ohio

Dataset Description: The OH Statewide Phase 2 2020 B20 lidar project called for the planning, acquisition, processing, and production of derivative products of QL1 lidar data to be collected at a nominal pulse spacing (NPS) of 0.35 meters. Project specifications were based on the U.S. Geological Survey National Geospatial Program Base Lidar Specification, Version 2021 revision A. The data was developed based on a horizontal reference system of NAD83 (2011) State Plane Ohio North (FIPS 3401) (EPSG 6549) and South (FIPS 3402) (EPSG 6551) and a vertical reference system of NAVD88 (GEOID18) US Survey Feet. Lidar data was delivered as processed LAS 1.4 files formatted to 1,250-feet by 1,250-feet tiles. Lidar was collected while no snow was on the ground and rivers were at or below normal levels. In order to post process the lidar data to meet task order specifications and meet ASPRS vertical accuracy guidelines, Woolpert established ground control points that were used to calibrate the lidar to known ground locations established throughout the entire project area. Additional independent accuracy checkpoints (NVA and VVA points), were collected throughout the entire project area and used to assess the vertical accuracy of the data. These checkpoints were not used to calibrate or post process the data.

Counties included: Fairfield, Gallia, Morgan

Formatted to 19,553 tiles, covering approximately 1096 square miles.

Lidar was collected from Dec 11, 2020 through April 11, 2021.

Block 6 (Work Unit 224915)

Counties included: Coshocton, Holmes, Knox, Tuscarawas

Formatted to 26,822 tiles, covering approximately 1503 square miles.

Lidar was collected from Nov 19, 2020 through April 5, 2021.

Woolpert established 17 ground control points and an additional 49 independent accuracy checkpoints (26 NVA points and 23 VVA points)

Block 7 (Work Unit 224919)

Counties included: Carroll, Harrison, Jefferson, Tuscarawas

Formatted to 24,656 tiles, covering approximately 1382 square miles.

Lidar was collected from Nov 24, 2020 through April 19, 2021.

Woolpert established 14 ground control points and an additional 48 independent accuracy checkpoints (25 NVA points and 23 VVA points)

Block 8 (Work Unit 224925)

Counties included: Carroll, Columbiana, Holmes, Mahoning, Stark, Tuscarawas, Wayne

Formatted to 42,505 tiles, covering approximately 1503 square miles.

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.

Process Steps

Process Step 1

CC ID: 1255613
Description:

Lidar Point Cloud Classification: The point cloud underwent a classification process to determine bare-earth points and non-ground points utilizing "first and only" as well as "last of many" lidar returns. This process determined Processed, but Unclassified (Class 1), Bare Earth Ground (Class 2), Low Noise (Class 7), Water (Class 9), Bridge Decks (Class 17), High Noise (Class 18), and Ignored Ground (Class 20). The bare-earth (Class 2 - Ground) lidar points underwent a manual QA/QC step to verify the quality of the DEM as well as a peer-based QC review. This included a review of the DEM surface to remove artifacts and ensure topographic quality. After the bare-earth surface is finalized, it is then used to generate all hydro-breaklines through a semi-automated process. All ground (Class 2) lidar data inside of the Lake Pond and Double Line Drain hydro flattening breaklines were then classified to water (Class 9) using TerraScan/LP360 macro functionality. A buffer of 0.7 meters was also used around each hydro-flattened feature to classify these ground (Class 2) points to Ignored Ground (Class 20). All Lake Pond Island and Double Line Drain Island features were checked to ensure that the ground (Class 2) points were reclassified to the correct classification after the automated classification was completed. These processes were reviewed and accepted by USGS through numerous conference calls and pilot study areas. All data was manually reviewed and any remaining artifacts removed using functionality provided by TerraScan and TerraModeler. Global Mapper was used as a final check of the bare earth dataset. GeoCue was then used to create the deliverable industry-standard LAS files. Woolpert proprietary software and LP360 was used to perform final statistical analysis of the classes in the LAS files, on a per tile level to verify final classification metrics and full LAS header information.

Process Step 2

CC ID: 1255832
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 the vertical units were converted to meters (NAVD88 Geoid18).

Process Step 3

CC ID: 1255833
Description:

The NOAA Office for Coastal Management (OCM) created references to the Entwine Point Tile (EPT) files 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.
