Abstract
ABSTRACT Seymour, A.C.; Ridge, J.T.; Rodriguez, A.B.; Newton, E.; Dale, J., and Johnston, D.W., 2018. Deploying fixed wing unoccupied aerial systems (UAS) for coastal morphology assessment and management. Accurate measurement of the morphology and distribution of coastal habitats is critical for understanding the function of coastal environments, assessing the resilience of coastal communities, and managing the coastal zone effectively. Unoccupied aerial systems (UASs, also known as unmanned aerial vehicles) and structure from motion (SfM) photogrammetry may be optimal for coastal surveys around small- or medium-sized municipalities, but guidance is needed to identify appropriate equipment configurations. Digital surface models (DSMs) from UAS equipped with mapping and survey-grade GPS units were processed with and without ground control point (GCP) correction, and their accuracy was compared to terrestrial laser scanner (TLS) derived DSMs and global navigation satellite system (GNSS) checkpoints. Four UA...
