Class 1: Unclassified and Class 2: Ground. Overlap points have been flagged as withheld. The timestamps are in absolute GPS time minus 1 billion, in accordance with the LAS 1.2 documentation. The following are the collection parameters and equipment used to create this data set. Aircraft: Piper Navajo (N6GR) Lidar System: Optech ALTM Gemini (03SEN145) Approximate Collection Altitude (Above Mean Terrain): 3800 meters Ground Speed: 160 kts Pulse Rate Frequency: 33 kHz Mirror Scan Frequency: 18 Hz Scan Angle (+/-): 16 degrees Beam Divergence: Narrow (0.25 mrad) Scan Cutoff: 0.02 degrees Accuracy statements are based on areas of moderate terrain, with points classified as ground. Diminished accuracies are to be expected in areas of extreme terrain and dense vegetation. The accuracy of each point is expected to meet the vertical accuracy standard, derived products may be less accurate in areas of extreme terrain and dense vegetation due to a lesser number of points defining the ground in these areas. Classified data sets such as this one may have varying posting due to some pulses not reaching the ground. Original contact information: Contact Name: Jacques Cloutier Contact Org: Aero-Metric, Inc.

The points were collected throughout the project area by John Seibert of Pro Survey Services. We recommend additional ground truth surveys of the data set to verify the vertical accuracy has not changed due to natural causes, such as techtonic motion or freeze/thaw cycles, and non-natural causes such as road construction. Without ground truth survey checks this data is not recommended for design grade mapping or engineering. ; Quantitative Value: 0.10 meters, Test that produced the value: Consolidated vertical accuracy at the 95th percentile along road and runway surfaces (meters). result: (missing) report: (DQ_CompletenessCommission) nameOfMeasure: Completeness Report evaluationMethodDescription: Complete result: (missing) report: (DQ_ConceptualConsistency) nameOfMeasure: Conceptual Consistency evaluationMethodDescription: Data has been verified using surveyed check points around the Fort Yukon Airport within the project area.

The files contained lidar elevation and intensity measurements. The data were received in projected coordinates of NAD83 UTM6N, meters and were vertically referenced to NAVD88 orthometric elevations using GEOID06(Alaska). The vertical units of the data were meters. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The topographic las files were converted from Projected Coordinates (NAD83 UTM6N, meters) to Geographic Coordinates (NAD83, decimal degrees). 2. The topographic las files were vertically converted from orthometric elevations (NAVD88) to ellipsoidal elevations (NAD83) with GEOID06. dateTime: DateTime: 2013-03-01T00:00:00 processStep: (LI_ProcessStep) description: The vertical values in this data set have been converted to reference North American Vertical Datum of 1988 (NAVD88) (GEOID12B) meters, using the GEOID12B grids provided by the National Geodetic Survey. Any datum and projection transformations were then done with the Office for Coastal Management 'datum_shift' program. Compression to an LAZ file was done with the LAStools 'laszip' program and can be unzipped with the same free program (laszip.org) Processing notes: dateTime: DateTime: 2023-07-01T05:08:13 processor: (CI_ResponsibleParty) individualName: NOAA Office for Coastal Management contactInfo: (CI_Contact) address: (CI_Address) electronicMailAddress: coastal.info@noaa.gov role: (CI_RoleCode) processor | |
