* » Abstract

The following are the collection parameters and equipment used to create these data sets:

Aircraft: Piper Navajo (812TB)

LiDAR System: Leica ALS70

Approximate Collection Altitude (Above Mean Terrain): 1070 meters

Ground Speed: 150 kts

Pulse Rate Frequency: 245 kHz

Mirror Scan Frequency: 60 Hz

Scan Angle (+/-): 15 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.

The NOAA Office for Coastal Management (OCM) downloaded this data set from this AK DGGS site:

https://elevation.alaska.gov/

These files were processed to make the data available for custom and bulk download from the NOAA Digital Coast Data Access Viewer (DAV) . The total number of files downloaded and processed was 1804.

In addition to these bare earth Digital Elevation Model (DEM) data, the lidar point data that these DEM data were created from, are also available. These data are available for custom download at the link provided in the URL section of this metadata record.
* Purpose

The purpose of this data set is to provide LiDAR-derived topographic data for transportation planning and road construction.

» Description

Created a smoothed-best estimated trajectory (SBET) of the sensor at a rate of 200 Hz, by integrating the airborne GPS and IMU data The basis of the GPS coordinates were two dual frequency GPS receivers, collecting data at a rate of 2 Hz operated by Aero-Metric during the acquisition phase of this project, and were referenced to NAD83 (CORS96) ellipsoid heights.

» Description

Processed data calibration: An in-situ calibration was performed using the data collect for this project. The data was classified in each line separately for ground and other common features between lines, such as building roofs. This data was processed in TerraMatch 11.001 (TerraSolid, Ltd.), to compute corrections for roll, pitch, heading, and mirror scale. These corrections are applied in order to minimize discrepancies between flight lines.

» Description

The NOAA Office for Coastal Management (OCM) downloaded 1804 raster DEM files in GeoTiff format from the Alaska DGGS Elevation Portal. The data were in AK State Plane Zone 4 NAD83 (2011), meters coordinates and NAVD88 (Geoid12A) elevations in meters. The bare earth raster files were at a 1 meter grid spacing.

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

1. Used an internal script to assign the EPSG codes (Horizontal EPSG: 6397 and Vertical EPSG: 5703) to the GeoTiff formatted files.

2. Copied the files to https.
