Abstract

This LiDAR dataset was created for the City of Eureka, California covering approximately 105 square miles of the city and its environs. The origin data was collected on September 24th, 2019 using a Leica Hyperion LiDAR mapping unit and associated ground control was collected by a California Certified PLS. All data was acquired and processed in California Zone 1 State Plane, NAD83(2011), NAVD88 in US Survey Feet. Datasets included 12 ppsm Bare Earth Classified LAS, 1-Foot DEM and a 1-Foot Interval Contour Extraction.

The lidar point, DEM, and imagery data was provided to the Office for Coastal Management (OCM) by the City of Eureka, CA for inclusion in the Data Access Viewer (DAV). OCM processed the lidar point, DEM, and imagery data to the DAV.

In addition to this lidar point data, the imagery and the DEM data that were created from the lidar point data, are also available. These data are available for custom download at the links provided in the URL section of this metadata record.

Data Quality

Horizontal Positional Accuracy:

Compiled to meet or exceed QL1 Standards

Vertical Positional Accuracy:

Compiled to meet or exceed QL1 Standards. Using 50 ground control locations within LiDAR calibration and point cloud post-processing, an average dz of -0.004', minimum dz of -0.199' and maximum dz of +0.148' were observed with an average magnitude of 0.063'. Observed RMSE was 0.082' (2.5 cm) with a standard deviation of 0.082'. Compilation results were not tested against independent ground control.

Completeness Report:

Datasets were reviewed visually for continuity.

Conceptual Consistency:

Quality Control procedures included manual assessments of automated results and visual association during the production process.

Lineage

Lineage Statement:

- 30 Percent Sidelap

- 17ppsm (Planned)

- 9 SNR (Minimum)

LiDAR Extraction & Deliverables:

- Bare Earth Classified LAS:

1) Processed, but Unclassified

2) Bare Earth

7) Low Noise

9) Water

10) Ignored Ground

17) Bridge Decks

18) High Noise

- DEM (1-Meter Posting)

- 1-Foot Contour Extraction

Process Step 2

CC ID: 1143857
Description:

The NOAA Office for Coastal Management (OCM) received 558 files in las format from the City of Eureka, CA. The lidar data had elevation and intensity measurements. The data were in CA State Plane, Zone 0401, NAD83 (2011), US survey foot coordinates and NAVD88 (assumed GEOID12B) elevations in feet. The data were classified as: 1 - Unclassified, 2 - Ground, 7 - Noise, 9 - Water, 17 - Bridge Decks, 18 - High Noise. There were also a minimal number of points in many other random classes. OCM processed the 1, 2, 7, 9, 17, and 18 classifications of points to the Digital Coast Data Access Viewer (DAV).

OCM performed the following processing on the data for Digital Coast storage and provisioning purposes:

1. The data were converted to laz format using laszip

2. The data were converted from gps week time to adjusted gps time using LAStools las2las

3. An internal OCM script was run to check the number of points by classification and by flight ID and the gps and intensity ranges.

4. File U_17 was determined to be corrupt. A replacement file was provided by Access Geographic, Inc, but this file was also found to be corrupt. OCM used Global Mapper to remove the offending points from the file.

5. Internal OCM scripts were run on the laz files to convert from orthometric (NAVD88) elevations to ellipsoid elevations using the Geoid12B model, to convert from CA State Plane Zone 0401 (NAD83 2011), US survey foot coordinates to geographic coordinates, to convert from vertical units of feet to meters, to assign the geokeys, to sort the data by gps time and zip the data to database and to http.
