Map Provides High-Resolution Look at Nearly Entire Arctic Region

Researchers highlight the value of the time element incorporated into imagery and having a baseline for revisiting and comparing topography.

“The Arctic, before we started, was one of the most poorly mapped places on Earth. It’s not anymore,” said Paul Morin, co–principal investigator of the ArcticDEM initiative, which has now released high-resolution digital elevation models (DEM) of 97.4% of the region. With this latest release, “we have a uniform product at 2-meter [resolution]” for all the land area north of 60°N latitude, plus those parts of Alaska, Greenland, and Russia’s Kamchatka Peninsula that are south of that point.

The public-private initiative plans to fill in the gaps with a final release in May 2018, according to Morin, director of the Polar Geospatial Center (PGC) at the University of Minnesota.
