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 these bare earth Digital Elevation Model (DEM) data, the imagery and the lidar point data that these DEM data were created from, 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.

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: 1293491
Description:

The NOAA Office for Coastal Management (OCM) received 600 files in .ASC format from the City of Eureka, CA. The bare earth raster files were at a 1 ft grid spacing. The data were in CA State Plane, Zone 0401, NAD83(2011), US survey foot coordinates and NAVD88 (assumed GEOID12B) elevations in feet. OCM converted the files from .ASC format to Geotiff format using gdal_warp. The files were then assigned the EPSG codes of 6416 (horizontal) and 6360 (vertical) and then copied to https for Digital Coast storage and provisioning purposes.
