Assessment of UAV Photogrammetric Mapping Accuracy in the Beach Environment
Abstract
Jeong, E.Y.; Park, J.-Y., and Hwang, C.-S., 2018. Assement of UAV Photogrammetric Mapping Accuracy in the Beach Environment In: Shim, J.-S.; Chun, I., and Lim, H.S. (eds.), Proceedings from the International Coastal Symposium (ICS) 2018 (Busan, Republic of Korea). Journal of Coastal Research, Special Issue No. 85, pp. 176–180. Coconut Creek (Florida), ISSN 0749-0208.This study evaluated the accuracy of UAV photogrammetry for subaerial beach morphology. Beach is characterized by complicated morphology due to the influence of coastal processes and is mainly composed of monochromatic sandy sediments. Therefore, it is required to validate the applicability of UAV photogrammetry that finds matching points from geographical features within images to create the 3D topographic data. For the accuracy test, a beach site which consisted of both typical sandy beach characteristics at the beach face and tidal flat features at the intertidal zone, was selected. The vertical accuracy of both the fixed-wing and the rotary-wing UAVs were tested using various flight altitudes, image overlap percentages, and GCPs configurations. The accuracy of the photogrammetric surveying results were examined by comparing them to reference data measured by LiDAR. The flight altitude should be set in such a way that the captured images include more geographical features in the beach environment, especially in the tidal flat. When the UAV photogrammetry is performed at a flight altitude of less than 150 m and…

Photogrammetry enables accurate documentation of archaeological sites with unprecedented quality at relatively low cost.
“Photogrammetry is a transformative practice in the development of contemporary archaeology, enabling accurate documentation of archaeological sites with unprecedented quality at a relatively low cost (Jeong et al. 2018).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
