Coastal Retrogressive Thaw Slumps from GeoEye-1, WorldView-2 and Aerial Photographs, 2011, Yukon Coast (CA)

Ramage, Justine L; Konopczak, Anna M; Herzschuh, Ulrike; Morgenstern, Anne; Couture, Nicole; Lantuit, Hugues

Coastal retrogressive thaw slumps (RTSs) were manually digitized at a 1:2000 scale using ArcMap (ESRI, version 10.3) from high‐resolution satellite images acquired in July (13 and 18), August (31), and September (13) 2011 (multispectral GeoEye‐1 and WorldView‐2—1.8 m resolution in multispectral and 0.5 m in panchromatic view). The RTSs were classified according to their activity. Characteristics were derived and morphological and spatial information for each coastal segment from an airborne lidar data set acquired in July 2013 were extracted.
