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3月漠阳江三角洲重点区滩面地形测量数据-YJ23-（实地测量-RTK）-20090319-20090319

“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±6 cm。

Coastline Position Dataset of Key Survey Areas for Coastal Erosion in Guangdong Province under the Special Project of "Comprehensive Marine Survey and Evaluation of China's Offshore Waters". The dataset covers the period from December 2007 to June 2009, and encompasses three key monitoring zones: the coasts on both sides of the Moyang River Estuary, the coast west of Shenquan Port in Huilai, and the coasts on both sides of the Hanjiang River South Estuary. This dataset mainly consists of repeated measurement data of coastline positions collected 5 times in each of the three key zones. The measurement instruments adopted were Hi-target RTK, with the Hypack navigation software used during the survey. The planar positioning accuracy of the RTK system was better than 1 m, the elevation accuracy was superior to 10 cm, and the data collection precision was set to ±6 cm throughout the data acquisition process.
