“…1,2). SPC techniques are commonly applied to constrain co-seismic rupture displacements (e.g., Michel et al, 1999;Dominguez et al, 2003;Avouac et al, 2006;Leprince et al, 2008;Oskin et al, 2012), glacial surface velocities (e.g., Scambos et al, 1992;Kääb, 2002;Berthier et al, 2005;Stearns et al, 2005;Debella-Gilo and Kääb, 2011;Willis et al, 2012;Melkonian et al, 2013), and landslide motions (e.g., Kääb, 2002;Delacourt et al, 2004). Use of high-resolution commercial images in such studies are advantageous for several reasons: increased spatial resolution over imagery such as Landsat-8, increased temporal resolution because of the ability to direct satellite viewing geometries, and the ability to analyze imagery from multiple sensors (e.g., Barnhart et al, 2011).…”
