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-2008年5月神泉湾重点区滩面地形测量数据HL11-（实地测量-RTK）-20080514-20080515

“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±17 cm。

Coastline Position Dataset of Key Coastal Erosion Investigation Zones in Guangdong Province under the National Offshore Marine Comprehensive Survey and Evaluation Special Project. This dataset covers the period from December 2007 to June 2009, and its coverage includes three key monitoring zones: the coasts on both sides of the Moyang River Estuary, the western coast of Shenquan Port in Huilai, and the coasts on both sides of Hanjiang South Port. The dataset mainly consists of 5 repeated measurement records of coastline positions in each of the three key zones. The measurement instruments used were Hi-target RTK and Hypack navigation software. The planar positioning accuracy of the RTK system is better than 1 meter, the elevation accuracy is better than 10 centimeters, and the data acquisition accuracy was set to ±17 cm during the collection process.
