The State of Alaska Division of Geological & Geophysical Surveys acquired photogrammetric digital surface models (DSMs) and co-registered orthorectified aerial images (orthoimages) for the west coast of Alaska in support of coastal vulnerability mapping efforts. This report is a summary of the data collected over 26 developed areas along approximately 3,500 km of coastline in the Bering Sea, Norton Sound, and Yukon-Kuskokwim Delta regions (fig. 1). Aerial photographs were collected between July 31 and September 6, 2015, and processed using Structure from- Motion (SfM) photogrammetry techniques. Ground control points (GCPs) and checkpoints were collected in support of these data products during a Global Navigation...

In July 2012, a helicopter-based crew photographed approximately 22 miles (35 km) of shoreline near Golovin, Alaska, from the Yuonglik River delta southeast to Portage Creek. During this flight 572 oblique aerial photographs were collected and spatially referenced using a Garmin Dakota 20 handheld GPS.

In July 2011, a helicopter-based crew photographed approximately 180 miles of shoreline along the eastern edge of Norton Sound, from Cape Denbigh to south of Unalakleet, AK. During this flight 2,180 oblique aerial photographs were collected and spatially referenced using a Garmin Dakota 20, handheld GPS. The communities of Unalakleet and Shaktoolik lie along the flight-line of this project.

Aerial photographs of the coastline from Teller to Nome were collected between August 26, 2015 - August 27, 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. Orthoimages contain 4-band, 8-bit, unsigned raster data (red/green/blue/no data; file format-GeoTIFF; source-Fairbanks Fodar) with 20 cm GSD. No-data values are found...

This report is a summary of a LiDAR data collection over the community of Unalakleet, in the Norton Sound region of Alaska. The original data were collected on October 27, 2005 by AeroMetric, Inc., under contract by Rodney P. Kinney and Associates, Inc. The complete, classified LiDAR dataset was purchased by the State of Alaska Division of Geological & Geophysical Surveys in 2013 in support of coastal vulnerability mapping efforts. For the purposes of open access to LiDAR datasets in coastal regions of Alaska, this collection is being released as a Raw Data File with an open end-user license.
