PHOTOGRAMMETRY OF MANGROVE FORESTS AND SURROUNDING MORPHROGY USING RTK-UAV

Abstract

 In tropical and subtropical countries, there is a strong trend to using mangrove forests as a disaster prevention function, and from a technological support perspective, it is important to survey mangrove forests and verify their disaster prevention effects. However, traditional surveys targeting mangrove forests commonly use leveling surveys, making it difficult to track changes in mangrove forests and surrounding morphology with large time-spatial scale.

 In this study, we conducted a photogrammetry using RTK-UAV targeting mangrove forests and surrounding morphology in the Nagura Bay of Ishigaki City. As a result, we verified that various parameters of mangrove morphology good accuracy local measurements, and we also conducted an analysis of factors influencing sediment accumulation trends on the offshore and onshore sides of mangrove forests.
