This elevation map of the Brooks Range Mountains in Alaska is part of a
set of maps created by researchers at The Ohio State University and the
University of Minnesota. The researchers took Worldview satellite data
and processed it with Ohio State software. The resulting maps, which
made their debut at the American Geophysical Union meeting on Dec. 18,
are the highest-resolution elevation maps ever created of the study
region, which so far covers part of Alaska and the Greenland Ice Sheet.
