The lidar data, acquired between 21 - Oct 25 2013, was processed by Watershed Sciences, Inc. (WSI) and consists of continuous coverage encompassing an area extending from Portage Lake eastward to Logging Company Bay in Passage Canal in the Seward D-4, D-5, and D-6 1:63,360-scale quadrangles. Lidar data collected below 1,600 ft (488 m) elevation have a minimum average pulse density of 8 pulses/square meter; above 1,600 ft (488 m) data were collected with an average pulse density of at least 4 pulses/square meter. Following lidar data collection and processing by WSI and their survey subcontractor, McClintock Land Associates, WSI submitted the data to the State of Oregon Department of Geology and Mineral Industries (DOGAMI) for independent quality control analysis. After addressing any concerns from DOGAMI, WSI submitted the revised dataset to DGGS along with a technical report describing details about the lidar acquisition, accuracy, and quality. DOGAMI also provided a separate report summarizing their methodologies and the results of quality control checks. The following data classifications are available for download from the NOAA Digital Coast: 1 (Unclassified) 2 (Ground) 3 (Low Vegetation) 4 (Medium Vegetation) 6 (Buildings) 7 (Low Point/Noise) 9 (Water Surface) 10 (Ignored Ground - Ground points within 1 m of breaklines) 14 (Withheld - Points that have intensity values of 0 or 255) 15 (Mobile - Temporary Placed Structures (cars, boats, docks, buoys)) 16 (Utilities - Man made non-habitable structures (fences, power lines)) Original contact information: Contact Name: James Weakland Contact Org: Alaska Division of Geological and Geophysical Surveys Title: GIS Analyst Phone: (907)451-5029 Email: dggsgis@alaska.gov This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data. purpose: In support of geologic mapping and hazards evaluation in and near Whittier, Alaska, the Division of Geological and Geophysical Surveys (DGGS) acquired, and is making publicly available, lidar (light detection and ranging) data for an area along Passage Canal, Portage Lake, and Portage Glacier Highway. Data will serve multiple purposes but were primarily collected to map geology and evaluate potential geologic hazards. Steep slopes with poor access, combined with dense vegetation and a thick moss ground-cover that obscures the bedrock surface, make the use of lidar one of the most effective ways to map the geology and evaluate unstable slopes and other hazards. credit: Financial support for this work came from State of Alaska capital-project funding. The authors are grateful for support from several staff members of the Division of Geological and Geophysical Surveys. Jim Weakland helped process data and create the hillshade images; Lauren Southerland helped organize the data for distribution; Susan Seitz created the programming by which the data are offered online; Simone Montayne assisted with metadata; and Ken Woods manages data on the server.

Shaded relief images have been visually inspected for data errors such as pits, border artifacts, gaps, and shifting. The data was examined at a 1:2000 scale. WSI submitted the data to the State of Oregon Department of Geology and Mineral Industries (DOGAMI) for independent quality control analysis. After addressing any concerns from DOGAMI, WSI submitted the revised data set to DGGS along with a technical report describing details about the lidar acquisition, accuracy, and quality. DOGAMI also provided a separate report summarizing their methodologies and the results of quality control checks. Both reports are available via the DGGS website or at: The Quality Control Report may be accessed at: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid12b/2580/supplemental/rdf2013_003_qc_report.pdf The Delivery Report may be accessed at: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid12b/2580/supplemental/rdf2013_003_delivery_report.pdf result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Horizontal Positional Accuracy evaluationMethodDescription: Horizontal accuracy is regarded as a product of the lidar ground footprint. Lidar is referenced to co-acquired GPS base station data that have accuracies far greater than the value of the lidar footprint. The ground footprint is equal to 1/3333rd of the above - ground flying height. The ground footprint for data collected for this project exceeds typical accuracy of ground control used to reference the lidar data (less than 0.01 meters). Project specifications require the lidar footprint to be between 0.15 and 0.40 meters. The values, tests, and processing methods used by WSI and DOGAMI to ensure relative accuracy are described in the accompanying delivery and quality control reports. Please see the lidar QC report at: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid12b/2580/supplemental/rdf2013_003_qc_report.pdf result: (missing) report: (DQ_AbsoluteExternalPositionalAccuracy) nameOfMeasure: Vertical Positional Accuracy evaluationMethodDescription: The vertical accuracy for this data set is 2.2 cm RMSE. Vertical accuracy was assessed by comparing GPS survey collected by McClintock Land Associates with lidar digital elevation models to expose offsets. Quality control analysis performed by DOGAMI, indicate that the data complies with project specifications (maximum root mean square vertical offset - 0.20 meters). Please see the lidar QC report for statistics from vertical accuracy analysis at: https://noaa-nos-coastal-lidar-pds.s3.amazonaws.com/laz/geoid12b/2580/supplemental/rdf2013_003_qc_report.pdf result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: The pulse density distribution varies throughout the study area. Areas below 1,600 feet in elevation, including the City of Whittier, were collected at a higher pulse density (greater or equal to 8 pulses/square meter), with areas above 1,600 feet in elevation collected at greater than or equal to 4 pulses/square meter. The WSI delivery report provides additional information about the lidar pulse density and distribution. Real time kinematic ground survey data (used for absolute vertical adjustment) is available in Appendix A of the delivery report. Aircraft flight-lines (trajectory files) were supplied to DOGAMI for quality control but are not included as a component of this publication.

OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The data were filtered for elevation outliers. 2. The data that were classified as 11, 12, and 13 were reclassified to classes 14, 15, and 16, respectively. The following data classifications are available for download: 1 (Unclassified), 2 (Ground), 3 (Low Vegetation), 4 (Medium Vegetation), 6 (Buildings), 7 (Low Point/Noise), 9 (Water Surface), 10 (Ignored Ground - Ground points within 1 m of breaklines), 14 (Withheld - Points that have intensity values of 0 or 255), 15 (Mobile - Temporary Places Structures (cars, boats, docks, buoys)), 16 (Utilities - Man made non-habitable structures (fences, power lines)) 3. The data were converted from GPS week time to Adjusted GPS time. 4. The data were converted from UTM Zone 6 (NAD83) coordinates to geographic coordinates. 5. The data were converted from NAVD88 (orthometric) heights to GRS80 (ellipsoid) heights using Geoid09. 6.
