High-resolution light detection and ranging (lidar) elevation data were acquired along the north coast of Alaska between 2009 and 2012. The lidar acquisition, from Icy Cape, Alaska to the United States/Canadian border, comprised approximately 11,000 km2. The airborne lidar data were acquired in support of the U.S. Geological Survey Coastal and Marine Geology Program. The purpose of this lidar acquisition was to produce highly detailed and accurate digital elevation data for shoreline change and coastal hazards assessments, and to make the data available to research scientists, natural resource managers, and the general public. 
 

USGS scientists also use high-resolution Alaska elevation data for evaluating landscape patterns and developing methodologies for characterizing and classifying features as they relate to shoreline change.
