Photogrammetric digital surface models and orthoimagery for the continuous coastline, Wales to Platinum, Alaska, segment F: Kotlik to Nunam Iqua

Aerial photographs of the coastline from Kotlik to Nunam Iqua were collected on August 31, 2015. The photographs were processed using Structure-from-Motion (SfM) photogrammetric techniques. Global Positioning System (GPS) checkpoints were collected via a Global Navigation Satellite System (GNSS) survey conducted between August 15 and September 14, 2015. For the purposes of open access to elevation and orthoimagery datasets in coastal regions of Alaska, this collection is being released as a Raw Data File with an open end-user license. This file is a single-band, 32-bit float DSM (digital surface model) which represents surface elevations of buildings, vegetation, and uncovered ground surfaces in meters with 20 cm GSD. The No Data value is set to -32767. The file employs LZW compression.

Shoreline change at Alaska coastal communities, Ekuk, Alaska

The Division of Geological & Geophysical Surveys has analyzed long-term shoreline change at 48 Alaska communities. Shoreline datasets were compiled from previously published U.S. Geological Survey assessments and created from historical and recent aerial images by the Alaska Division of Geological & Geophysical Surveys. Shorelines were analyzed to calculate shoreline change rates every 25 meters along coastlines and tidally influenced riverbanks using the Digital Shoreline Analysis System (DSAS; Himmelstoss and others, 2018). The geodatabase for each community includes shoreline positions, the alongshore baseline used to cast transects, and transects that include shoreline change rates and statistics. All files can be downloaded free of charge from the Alaska Division of Geological & Geophysical Surveys website (http://doi.org/10.14509/30552).

Regional tsunami hazard assessment for communities on the Kenai Peninsula, Alaska

We assess potential tsunami hazard for three coastal communities on the Kenai Peninsula, Alaska: Anchor Point, Nanwalek, and Port Graham. The primary tsunami hazard for these communities is considered to be near-field, with a major threat originating from tsunamigenic earthquakes along the Alaska-Aleutian megathrust. We numerically model tsunamis generated by three different megathrust earthquakes and two volcanic sources, analyze tsunami wave dynamics, and develop approximate tsunami hazard maps for the communities. The hypothetical tsunami scenarios that we examined simulate Mw 9.0 megathrust earthquakes with a slip distribution in the 5-35 km (3-22 mi) depth range along the Alaska-Aleutian megathrust, as well as tsunamigenic mass flows originating from Augustine Volcano. The maximum runup heights are 12.2 m (40 ft) in Anchor Point, 14 m (46 ft) in Nanwalek, and 14.9 m (49 ft) in Port Graham. Results presented here are intended to provide guidance to local emergency management agencies in initial tsunami inundation assessment, evacuation planning, and public education for mitigation of future tsunami hazards. The complete report and digital data are available from the DGGS website: http://doi.org/10.14509/30194.

High-resolution lidar data for infrastructure corridors, Wiseman Quadrangle, Alaska

In advance of design, permitting, and construction of a pipeline to deliver North Slope natural gas to out-of-state customers and Alaska communities, the Division of Geological & Geophysical Surveys (DGGS) has acquired lidar (Light Detection and Ranging) data along proposed pipeline routes, nearby areas of infrastructure, and regions where significant geologic hazards have been identified. Lidar data will serve multiple purposes, but have primarily been collected to (1) evaluate active faulting, slope instability, thaw settlement, erosion, and other engineering constraints along proposed pipeline routes, and (2) provide a base layer for the state-federal GIS database that will be used to evaluate permit applications and construction plans. The highest-hit digital surface models (DSM) represent the earth's surface with all vegetation and human-made structures included.
