The Division of Geological & Geophysical Surveys (DGGS) offers this application as a public service to users with an interest in or a need for elevation data for Alaska. This data is extremely useful for our scientific staff and difficult to obtain. As we searched for publicly available data, we created an efficient, user-friendly method to allow download or online use of the data. We hope that this application will help users more easily obtain and download the information they need and simplify mapping and data application in Alaska.

DGGS thanks the following organizations for contributing elevation data to this project. Their dedication, commitment, and willingness to be involved have helped us collect this elevation data for distribution.

U.S. Geological Survey

The USGS is a science organization that provides impartial information on the health of our ecosystems and environment, the natural hazards that threaten us, the natural resources we rely on, the impacts of climate and land-use change, and the core science systems that help us provide timely, relevant, and useable information.

The Geographic Information Network of Alaska

GINA is a mechanism within the University of Alaska (UA) for sharing data and technical capacity among Alaskan, Arctic, and world communities. Established in 2001 as an initiative of UA’s President, GINA promotes collaboration at the local, state, and federal levels by increasing community-wide participation in the discovery and use of geospatial data. GINA’s products and services greatly expand the range of available analysis capabilities in order to better address research and management requirements.

The Alaska Geospatial Council / Alaska Statewide Digital Mapping Initiative

The Statewide Digital Mapping Initiative (SDMI) was created in 2006, with the mission of developing a new digital base map of Alaska. SDMI consisted of the Alaska Departments of Natural Resources, Fish and Game, Environmental Conservation, Military and Veterans Affairs, Transportation, and Commerce and Economic Development, and the University of Alaska. SDMI formed strong partnerships with the federal agencies, and acquired funding to build the two initial components of the state base map: a current orthomosaic satellite image, and a new accurate digital elevation model (using INSAR). The orthomosaic is complete, and the elevation model is over 50% complete. In 2014, the SDMI was re-formed as the Alaska Geospatial Council, with a broadened mission to improve coordination of all geospatial data. State agencies and federal partners are currently seeking funding to complete the INSAR data acquisition.

National Oceanic and Atmospheric Administration

NOAA’s Mission: Science, Service, and Stewardship. To understand and predict changes in climate, weather, oceans, and coasts, to share that knowledge and information with others, and to conserve and manage coastal and marine ecosystems and resources. NOAA’s Vision of the Future: Resilient Ecosystems, Communities, and Economies. Healthy ecosystems, communities, and economies that are resilient in the face of change.


OpenTopography facilitates community access to high-resolution, Earth-science-oriented topography data and related tools and resources.

Federal Emergency Management Agency

FEMA's mission is to support our citizens and first responders to ensure that as a nation we work together to build, sustain, and improve our capability to prepare for, protect against, respond to, recover from, and mitigate all hazards.

Alaska Department of Transportation & Public Facilities

DOT&PF’s Mission: Keeping Alaska moving through service and infrastructure, by providing for the safe and efficient movement of people and goods, statewide access and connectivity, and access for exploration and development of Alaska's resources.

The Natural Resources Conservation Service

The NRCS draws on a long history of helping people help the land. For 80 years, NRCS and its predecessor agencies have worked in close partnerships with farmers and ranchers, local and state governments, and other federal agencies to maintain healthy and productive working landscapes.

The Matanuska–Susitna Borough

The Mat–Su Borough was incorporated as a second-class borough in 1964 with a manager form of government, governed by an elected mayor and Assembly. Borough services are provided on an area-wide and non area-wide basis. Area-wide services are provided both inside and outside the incorporated cities of the Borough. Non area-wide services may only be provided outside of incorporated cities. The Mat–Su Borough employs more than 300 people and is responsible for 70 plus facilities in a 24,000 square mile area (roughly the same size as Ireland).

The Kenai Watershed Forum

The Kenai Watershed Forum is a local 501(c)(3) non-profit organization dedicated to maintaining the health of the watersheds on Alaska’s Kenai Peninsula. KWF is recognized as the regional watershed organization of the Kenai Peninsula, successfully identifying and addressing the needs of the region by providing high-quality Education, Restoration, and Research programs. Its mission: Working together for healthy watersheds on the Kenai Peninsula. KWF is a dynamic and maturing organization poised to serve the Kenai Peninsula and the state with increasing effectiveness in the near and distant future.
