Unmanned Aerial Vehicle Photogrammetry Based Dataset of Halophyte Distribution in Jujin Estuary

The importance of blue carbon is significant in terms of climate change mitigation and marine ecosystem conservation, and halophyte acts as a crucial reservoir for this blue carbon. Accordingly, this study utilized unmanned aerial vehicle (UAV) optical sensors to create a distribution map of vegetation in the natural salt marsh of the Jujin estuary. The optical images captured from a UAV at an altitude of 50 m provide ultra-high-resolution optical information with a ground sampling distance of 0.6 cm. Based on these images, a U-Net model was trained to classify <i>Phragmites communis</i> and <i>Suaeda maritima</i>, generating a classification map of the mixed habitats of salt marsh plants. The areas of <i>Phragmites communis</i> and <i>Suaeda maritima</i> in the Jujin- Cheon region were found to be 6,653.23 m<sup>2</sup> and 1,409.08 m<sup>2</sup>, respectively. The classification results were validated using field control point data, confirming an approximate classification accuracy of 92%.
