摘要
利用卫星遥感影像进行大比例尺海岛(礁)测绘过程中,为解决独立无控岛屿立体测图和海岸线内业测量精度低以及海岸带不接边等技术问题,对在实际生产中应用的稀少控制区域网平差、海岸线潮位推算法和要素接边原则等关键技术进行了论述,并通过数据分析得出了技术应用的正确性,为今后利用高分辨率卫星遥感影像进行海洋测绘提供借鉴。
In the process of large scale surveying and mapping for islands/reefs using satellite remote sensing imagery,some technical problems frequently arise,such as difficulties in performing three-dimensional mapping of isolated island,low precision of coastline measurement and mismatches among coastal zone edges and so on. In order to solve the above problems,some key techniques associated with actual production are addressed in the paper,which include the rare control area net adjustment,the coastline tide level calculation method and the factors of edge principle. The validity of the technology is concluded through the data analysis. The work provides a reference for marine surveying and mapping using high-resolution satellite remote sensing imagery in the future.
