Alaska is last frontier in USGS re-mapping project

Since 2009, the U.S. Geological Survey has been working on its most extensive and intricate mapping project ever: the US Topo project. It aims to re-map the entire U.S. in digital topographic format, along with aerial imagery and hydrography. The project's director tells Talkeetna radio station KTNA about the challenges of incorporating Alaska into the project.

[Mark] DeMulder has been overseeing the US Topo project since its inception in 2009, and Alaska is the final piece of the puzzle. For the first time since the middle of the last century, a total re-mapping of the state is now under way. DeMulder says the transformation in technology will result in the most detailed, accurate statewide topo maps we've ever seen. ... DeMulder says that part of what makes mapping Alaska so challenging, is that much of the information has never been collected before.
