High-resolution lidar data for infrastructure corridors, Valdez 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 dataset represents ground-classified laser returns from the lidar survey and their associated geospatial coordinates.

Photogrammetric digital surface models and orthoimagery for the continuous coastline, Wales to Platinum, Alaska, segment O: Eek to Goodnews Bay

Aerial photographs of the coastline from Eek to Goodnews Bay were collected on May 4, 2016 - May 5, 2016. 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.

High-resolution lidar data for infrastructure corridors, Mount Hayes 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 normalized digital surface models (nDSM) represent the above ground elevation of the highest laser return with all vegetation included.

Engineering-geologic map of the Dalton Highway from Galbraith Lake to Slope Mountain, southern Arctic Foothills, Alaska

This derivative engineering-geologic map illustrates potential near-surface sources of various geologic materials that may be useful for construction near the Dalton Highway area, from Atigun Gorge to Slope Mountain. The map area is located in the west-central Philip Smith Mountains quadrangle. The map extends from the northern flank of the Endicott Mountains into the Arctic Foothills province. Field observations indicate that each geologic unit (for example, stream alluvium) has a definite composition or range of composition. Therefore, the probable presence of materials is interpreted from the distribution of geologic units on the geologic map of this quadrangle. Map unit descriptions also include discussion of the potential geologic hazards that can be inferred from the typical physical properties of each map unit, such as sediment texture and ground-ice content and typical topographic settings. This map is generalized and is not intended to show exact locations of specific materials. Local variations are common, especially near unit boundaries. The map was derived electronically from a related surficial geologic map of the area using Geographic Information System (GIS) software. Geologic units were locally verified by ground observations during field visits. The results should be considered reconnaissance in nature.

Geologic Map Index of Alaska

The Geologic Map Index of Alaska (Map Index) is a GIS web feature service paired with an interactive web map application that provides access to an actively growing geographic index of geology-related maps of Alaska and adjacent areas. This online research tool provides the locations and outlines of most DGGS and U.S. Geological Survey (USGS) geologic maps of Alaska in a single, interactive web application. It allows searches of the map database by geographic area of interest, keywords, publishing agency, dates, and other criteria. The search results link DGGS's comprehensive, multi-agency publications database, where users can view and download publications for free. Map Index provides access to traditional geologic maps and sample location, geologic hazards, and geologic resources maps. In addition, DGGS plans to add outlines and data to the application for new and remaining geologic maps published by DGGS, USGS, U.S. Bureau of Mines, and U.S. Bureau of Land Management. Reports without maps can be accessed through DGGS's comprehensive publications database, <http://dggs.alaska.gov/pubs/advanced-search>.

Photogrammetric digital surface models and orthoimagery of Lake O the Hills neighborhood, December 5, 2018

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 Lake O the Hills neighborhood and was collected on December 5, 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.

Airborne electromagnetic and magnetic survey, Goldstream Creek watershed, interior Alaska

The Goldstream geophysical survey dataset provides airborne electromagnetic and magnetic data and resistivity models from a 258-square-km portion of the Goldstream Creek watershed, interior Alaska. The survey was flown from March 6th to March 17th, 2016, by CGG Canada Ltd. using their RESOLVE airborne geophysical system. Survey line spacing was either 100 meters (m) or 200 m; additional custom lines were collected over areas of scientific interest. The data were measured from 30 m above the ground surface using a helicopter-towed sensor platform ('bird') on a 30-m long line. The geophysical survey provides a snapshot of subsurface electromagnetic and magnetic variability throughout the study area. The data and resistivity modeling facilitates interpretation of surface and subsurface features and processes within Goldstream Valley and surrounding areas of interior Alaska. The Goldstream Valley Watershed project is funded by the National Science Foundation, Office of Polar Programs, Arctic System Science Program, award #1500931. Users can access the originating data and additional project metadata from the DGGS website: http://doi.org/10.14509/29681.
