The National Geospatial-Intelligence Agency launched a public website Sept. 2 to provide unclassified information about the Arctic.
The public site, accessible located at nga.maps.arcgis.com, includes Digital Elevation Models that provide 3D representations of the Arctic’s surface.
The models, derived from NGA-sponsored DigitalGlobe commercial imagery sources, support land management, sustainable development, safe recreation, scientific studies, and domain-specific challenges inherent to aviation, transportation and defense. The DEM is the standard against which landscape changes such as erosion will be measured.
NGA’s Arctic website also includes NGA nautical charts, sailing directions, shape files and infographics.
A large, downloadable Pan-Arctic map includes multiple layers that allow users to focus on specific issues and information. Layers include search and rescue zones, ice extents, economic exclusion zones, bathymetric data, navigational and meteorological warnings, and potential energy sources.
