Evaluation and enhancement of unmanned aircraft system photogrammetric data quality for coastal wetlands

Understanding the impacts of flight configuration and post-mission data processing techniques on unmanned aircraft system (UAS) photogrammetric data quality is essential for employing this popular technique in coastal wetland ecosystems. In this study, we systematically evaluated the effects of flight configuration (flying altitude, image overlap, and lighting conditions) on UAS photogrammetric level 1 products: orthoimagery and point clouds,...
