This metadata record describes the unclassified, last return, point cloud data for the 2011 USGS North Slope of Alaska lidar project. This record was created by the NOAA Office for Coastal Management (OCM) because no metadata record or data report were available for the data. Information to create this record was found here: https://topotools.cr.usgs.gov/posters/arctic_coast_alaska.pdf and from the tile metadata for AK_NORTHSLOPE_UTM4_2011_000001 at USGS EarthExplorer.
This 2011 data set is part of the USGS assessment of coastal change hazards, over 11,000 km2 of airborne lidar elevation data were collected along the Arctic coast of Alaska between 2009 and 2012. Data coverage includes the barrier islands and mainland coast between Icy Cape and the U.S.–Canadian border, from the shoreline to ~1.5 km inland. Data coverage extends further inland to around 3 km on the Barrow Peninsula and along the coast of the Teshekpuk Lake Special Area (TLSA) where coastal erosion rates are among the highest in the world (> 18 m/yr). Nominal point density is 1.5 m and vertical accuracy is better than 30 cm. Data were not collected over most river deltas or large embayments, with the exception of Admiralty Bay, Smith Bay (Ikpikpik Delta), Kogru River, and the Fish Creek portion of Colville River Delta. The primary use of the lidar data is to establish a modern shoreline position to be used for change analyses with historical shoreline positions. However, the lidar DEM provides a wealth of topographic and intensity data that can be used for morphological mapping of the remote arctic coast.
This is one of the first comprehensive lidar datasets collected in a continuous permafrost environment. Many periglacial landscape features, such as patterned ground, ice-wedge polygons, and thermokarst lakes and former lake basins (recent and relict) are discernible in the dataset. Traditional coastal landscape features including shoreline position, beach width, slope, and bluff height and morphology are also distinct.

The NOAA Office for Coastal Management (OCM) downloaded this lidar data from the AK DGGS site (https://elevation.alaska.gov/) and processed the data to be available on the Digital Coast Data Access Viewer (DAV).
This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
The primary use of the lidar data is to establish a modern shoreline position to be used for change analyses with historical shoreline positions.

The NOAA Office for Coastal Management (OCM) downloaded 500 laz files from the Alaska Division of Geological and Geophysical Surveys data Portal (https://elevation.alaska.gov/). The files contained unclassified (last return) elevation and intensity measurements for the 2011 North Slope AK data set. The data were in UTM Zones 4 and 5 coordinates and ellipsoid (GRS80) elevations in meters. The data were unclassified last returns. The NOAA Office for Coastal Management processed all points to the Digital Coast Data Access Viewer (DAV).
OCM performed the following processing on the data for Digital Coast storage and provisioning purposes:
1. The LAStools software scripts lasinfo and lasvalidate were run on the laz files to check for errors.
2. An internal OCM script was run to check the number of points by classification and by flight ID and the gps and intensity ranges.
3. Internal OCM scripts were run on the laz files to convert from UTM Zone 4 and 5 coordinates to geographic coordinates, to assign the geokeys, to sort the data by gps time and zip the data to database and to http.

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)
