摘要

摘要海洋结构物是位于海岸线上的重要人造物体,在航海、海岸工程和城市规划中引起了极大的关注。在地图综合过程中,一些海上结构需要倒塌。在我们的研究中,首先,分析了这些海事结构的表征特征。其次,基于这些特征,开发了一种自动识别这些可能倒塌的海事结构的方法,同时提取其部分比例符号。第三,基于尺度驱动阈值,通过选择提取的部分比例符号来实现塌陷方法的自动化,并与海岸线简化相结合。最后,在各种海岸线和海事结构上对所提出的方法进行了测试,实验结果表明,我们的方法对于瓦解海事结构和与简化操作员合作实现海岸线的自动综合是有效的。

An Automated Approach to Coastline Simplification for Maritime Structures with Collapse Operation
Abstract Maritime structures are significant man-made objects located along coastlines that have drawn considerable attention in maritime navigation, coastal engineering, and urban planning. During the process of map generalization, some maritime structures need to be collapsed. In our study, first, the representation characteristics of these maritime structures are analysed. Second, based on these characteristics, an automated approach of identifying these maritime structures that will potentially be collapsed while simultaneously extracting their partially proportional symbols is developed. Third, based on scale-driven thresholds, the collapse method is automated by selecting extracted partially proportional symbols and is collaborated with coastline simplification. Finally, the proposed approach is tested on various coastlines and maritime structures, and the experimental results demonstrate that our approach is effective for collapsing maritime structures and collaborating with the simplification operator for the automated generalization of coastlines.

期刊介绍: The aim of Marine Geodesy is to stimulate progress in ocean surveys, mapping, and remote sensing by promoting problem-oriented research in the marine and coastal environment. The journal will consider articles on the following topics: topography and mapping; satellite altimetry; bathymetry; positioning; precise navigation; boundary demarcation and determination; tsunamis; plate/tectonics; geoid determination; hydrographic and oceanographic observations; acoustics and space instrumentation; ground truth; system calibration and validation; geographic information systems.
