摘要
海图自动综合研究由传统地图综合研究和海部要素综合算法两部分组成,是海图生产自动化的瓶颈之一。简要分析了海图海部要素综合算法的特点,思考和展望了海图综合的未来发展方向:深入研究海部要素的特征,重视基于三维模型等全局性综合算法,加强海图自动综合的系统化和工程化,以及海洋信息多尺度表达的研究。
Automatic generalization is one of the bottlenecks in automatic production of nautical charts, whose framework is composed of two parts: traditional map generalization research and marine elements generalization algorithm.This paper analyzes briefly the algorithms for automatic generalization of marine element, suggests that further research should focus on the characteristics of marine element, attaches importance to global algorithm based on 3D seabed terrain model, strengthens research to achieve systemizing and engineering, and pays more attention to multi-scale expression of marine spatial information.
