three-dimensional topographic maps of the entire state of Alaska. The digital elevation models, or DEMs, serve as a benchmark for measuring future climate changes in the Arctic by assisting ...

high-resolution maps of Alaska. He made good on that promise this week with the release of the first set of maps, called Arctic digital elevation models or ArcticDEMs, created through the National ...

A digital elevation model of Anchorage, Alaska, shows planes parked off the runway of Ted Stevens International Airport. Better elevation maps can be used to quantify changes in sea level and ...

Previous topographic maps of Alaska only resolved to about 100 feet across. But the new data, called Arctic Digital Elevation Models, or ArcticDEMs, based on satellite imagery, has a resolution ...

The satellites captured the same location twice, 45 seconds apart, before sending them to a supercomputer which was able to combine them and extract elevation ... that the Alaska map has been ...

Current elevation models for the Arctic have a resolution ... and enable a host of other research. Alaska’s DEMs are the first maps released by the project, but their goal is to cover the whole Arctic ...

Prior to this effort, topographical maps for much of Alaska were about 50 years out of date and not produced to current standards, which rely largely on high resolution digital imagery and elevation ...
