海洋自然岸线确定试点研究

Pilot Study on the Determination of Marine Natural Coastline

以河北省沿海典型区域为试点,开展海洋自然岸线确定研究。主要通过收集获取试点区域影像资料、海洋岸线、潮汐等专题资料,利用GNSS导航定位、无人机、内业影像解译、外业调查核查等多种技术方法,确定基于不同技术路线的海洋岸线采集方案,针对各类自然岸线,开展平均高潮线、平均低潮线、0m等高线的确定及信息提取工作。

This paper takes typical coastal areas of Hebei Province as the pilot to carry out the determination of marine natural coastline. Through collecting and acquiring the image data,ocean shoreline and tidal data of the pilot area,and using GNSS navigation and positioning, UAV,interior image interpretation,field investigation and verification and other technical methods,the ocean shoreline acquisition scheme based on different technical routes is determined,and carries out the determination and information extraction of the average high tide line,the average low tide line and the 0m contour line for all kinds of natural shorelines.
