US: The National Geospatial-Intelligence Agency (NGA) has developed a public website to publish unclassified information about the Arctic. The site supports efforts to strengthen international cooperation, better understand and manage resources responsibly, improve living conditions in the Arctic and maintain valuable and vulnerable ecosystems.
The public site, accessible through www.nga.mil and located at nga.maps.arcgis.com, includes Digital Elevation Models (DEM) 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. A large, downloadable Pan-Arctic map available on the site includes multiple layers that allow users to focus on specific issues and information.
