Alaska Spill Planning Tool Expands to Coastal Mapping

The coastal mapping endeavor ShoreZone’s Alaska debut was as a Cook Inlet Regional Citizens Advisory Council pilot project in 2001. Now, about 80 percent of Alaska’s coastline is mapped including Southeast Alaska and the North Slope. ShoreZone provides public access to a coastal map that includes several elements: high-resolution photos, videos, and data on the
