中国科学院南海海洋研究所--广东省海岸侵蚀灾害调查与研究-2009年2月韩江三角洲重点区水深测量数据-HJ23-（实地测量-Knudsen Engineering Ltd 320M）-20090224-20090224

“我国近海海洋综合调查与评价”专项广东省海岸侵蚀重点调查区岸线位置数据集，覆盖时间为2007年12月至2009年6月，覆盖区域为三个重点监测区，分别为漠阳江口两侧海岸、惠来神泉港西侧海岸和韩江南港口两侧海岸。该数据集主要是三个重点区各5次岸线位置的重复测量数据，测量仪器为中海达RTK，使用Hypack导航软件，其中RTK平面定位优于1 m、高程优于10 cm，数据采集过程中设置采集精度±13 cm。

Dataset of Shoreline Positions in Key Coastal Erosion Survey Areas of Guangdong Province under the Special Project of Comprehensive Marine Survey and Evaluation of China's Offshore Waters. This dataset covers the time period from December 2007 to June 2009, and includes three key monitoring zones: the coastal areas on both sides of the Moyang River Estuary, the western coast of Shenquan Port in Huilai, and the coastal areas on both sides of the Hanjiang River South Port. The dataset primarily consists of 5 rounds of repeated shoreline position measurements conducted in each of the three zones. The measurements were carried out using Hi-Target RTK instruments and Hypack navigation software, with the RTK achieving a planar positioning accuracy better than 1 meter and elevation accuracy better than 10 centimeters, and the data acquisition accuracy was set to ±13 cm during the collection process.
