Civil Air Patrol (CAP) imagery, often the first post-disaster observation, is designed for 2D interpretation rather than multi-temporal volumetric measurement. We build post-storm digital surface and terrain models from uncontrolled CAP imagery with structure-from-motion in western North Carolina’s open Swannanoa Valle...
