摘要
线要素自动综合一直是自动制图综合中的重要研究内容。对海图线要素的自动综合背景、现状和发展方向进行了论述,对数字海图要素的自动选取方法进行了研究,并分析了海岸线制图综合的基本原则和分形、分维方法在海岸线自动综合中的应用。在对线状要素的分布规律和特征以及制图综合指标的确定进行研究的基础上,提出了海岸线自动综合的量化、模型化、算法化的一些具体实现方法,初步实现了一定程度上的海岸线自动综合。
Line simplification has been found to be one of the most important aspects in automatic cartographic generalization.The background,status and the trend of the automated generation were discussed,and the research on the method of auto selection of the marine features on digital charts were carried out.The principles of the coastline generalization and an application in automatic coastline cartographic generalization with fractals and fractal dimension were analyzed.Based on a research about distribute regulation and characteristics of the linear features and the assurance of the target of the automated generalizations,some realization methods of quantization,modeling and algorithmization material ways about marine features on digital charts were put forward,and the automatic generalizations of coastline at a certain extent were preparatorily realized.
