2010 U.S. Geological Survey (USGS) Topographic Lidar: Channel Islands, California

Dataset Identification:

Resource Abstract:
Terrapoint collected LiDAR for 197 square miles covering five islands off the coast of Los Angeles, California. These islands are part of the Channel Islands National Park and consists of San Miguel Island, Santa Rosa Island, Santa Cruz Island, Anacapa Island, and Santa Barbara Island. The nominal pulse spacing for this project was better than 0.7 meters. This project was collected with a sensor which collects waveform data and provides an intensity value for each discrete pulse extracted from the waveform. GPS Week Time, Intensity, Flightline and echo number attributes were provided for each LiDAR point. Dewberry used proprietary procedures to classify the LAS according to USGS ARRA specifications: 1-Unclassified 2-Ground 7-Noise 9-Water 10-Ignored Ground due to breakline proximity. Dewberry produced 3D breaklines, seamless DSMs, and seamless hydro flattened DEMs for the 204 tiles (2000 m x 2000 m) that cover the project area. Area mapped by island is as follows: Santa Barbara Island-1 sq. mi. Anacapa Island-1 sq. mi. San Miguel Island-15 sq. mi. Santa Rosa Island-83 sq. mi. Santa Cruz Island-97 sq. mi. Two UTM zones cover the Channel Islands. The islands delivered per each UTM zone are as follows (please note that Santa Rosa Island was delivered in both UTM zone 10 and UTM zone 11): UTM Zone 10: Santa Rosa Island San Miguel Island UTM Zone 11: Santa Barbara Island Santa Rosa Island Santa Cruz Island Anacapa Island The NOAA Coastal Services Center received the data in UTM Zones 10 and 11. The data were converted to geographic coordinates and from NAVD88 heights to ellipsoid heights using GEOID09. These files were converted for data storage and Digital Coast provisioning purposes.

AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy Report
evaluation Method Description  Lidar source compiled to meet 1.07 m (3.5 ft) horizontal accuracy.
AbsoluteExternalPositionalAccuracy
name Of Measure Horizontal Positional Accuracy
measure Description  Dewberry does not perform independent horizontal accuracy testing on the LiDAR. LiDAR vendors perform calibrations on the LiDAR sensor and compare data to adjoining flight lines to ensure LiDAR meets the 1.07 m (3.5 ft) horizontal accuracy standard at the 95% confidence level.

AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy Report
evaluation Method Description  The vertical accuracy of the LiDAR was tested by Dewberry with 25 independent survey checkpoints. The survey checkpoints were distributed throughout the project area. Due to the small area being mapped and the land cover of the islands, vertical accuracy was not tested for multiple land cover types. All checkpoints were used to compute the Consolidated Vertical Accuracy (CVA). Project specifications required a CVA of 30 cm (RMSEz 15 cm) at the 95% confidence level based on FEMA and NSSDA methodology.
AbsoluteExternalPositionalAccuracy
name Of Measure Vertical Positional Accuracy
measure Description  Based on the vertical accuracy testing conducted by Dewberry, using NSSDA and FEMA methodology, vertical accuracy at the 95% confidence level (called Accuracyz) is computed by the formula RMSEz x 1.9600. The dataset for the USGS Channel Islands project satisfies the criteria: Lidar dataset tested 0.06 m vertical accuracy at 95% confidence level for all land cover types, based on consolidated RMSEz (0.03 m) x 1.9600.
Quantitative Result
result value 0.06
value Units
Completeness Commission
evaluation Method Description  A visual qualitative assessment was performed to ensure data completeness and bare earth data cleanliness. No void or missing data, the bare earth surface is of good quality and data passes vertical accuracy specifications.
ConceptualConsistency
measure Description  Data covers the tile scheme provided for the project area.
