DGPS Lake Shoreline Dataset from Field Survey



Shorelines for thaw lakes on the Alaskan North Slope were mapped in the field using high accuracy Differential Global Positioning System (DGPS). Three field sites were mapped over three years beginning with the Barrow peninsula in 2008, near the town of Atqasuk in 2009, and at the southern limit of North Slope lakes in 2010 with about a dozen lakes at each site. These three field sites form a North-South transect of the North Slope.
