Photogrammetry-derived orthoimagery and elevation data for Kongiganak, Alaska, collected June 7, 2023, Raw Data File 2024-20, provides low-altitude aerial images from an unmanned aerial vehicle (UAV) in the community of Kongiganak, Alaska, on June 7, 2023. We used Structure-from-Motion (SfM) photogrammetry to produce two digital surface models (DSM) and two orthorectified images. The populated areas of Kongiganak were the focus of the primary aerial survey, while the secondary aerial survey covered the landfill to the northwest of the community. The orthoimage and elevation data are useful for assessing riverine hazards and changes over time.

The State of Alaska Division of Geological & Geophysical Surveys (DGGS) produced digital surface models (DSMs) and orthorectified aerial imagery (orthoimagery) over selected locations in the greater Anchorage area following the Mw 7.1 November 30, 2018, Anchorage earthquake. We selected areas of interest (AOIs) based on initial damage reports from the Alaska Department of Transportation & Public Facilities (DOT&PF) and the United States Geological Survey (USGS) in order to document earthquake effects. Aerial photographs collected December 5-6, 2018, were processed using Structure-from-Motion (SfM) photogrammetric techniques to create sub-meter DSMs and orthoimagery. This digital data set covers Potter Creek and was collected on December 6, 2018. These data document ground conditions immediately following the 2018 Mw 7.1 Anchorage earthquake. For the purposes of open access to elevation and orthoimagery data sets throughout Alaska, this collection is being released as a Raw Data File with an open end-user license. The data and the data acquisition report are available from the DGGS website: https://elevation.alaska.gov/, http://doi.org/10.14509/30280.
