摘要
针对传统海图图幅设计存在的主观性高、效率低下等问题,在分析海图图幅类型、设计原则的基础上,面向海图图幅设计涉及的相关参数,采用大地坐标转换、投影计算等基础数学方法,提出了海图图幅的自动设计算法,实现了给定图幅参数条件下比例尺、图幅规格的自动转换。
To solve the existing problems such as high subjective and low efficiency in traditional chart sheet design procedure, we analyzed the type and design principle of chart sheet, and summarized the relative parameters of chart sheet design. And then, we used the basic mathematics methods of geodetic coordinate system transformation and projection calculation in chart sheet design procedure to put forward a chart sheet automatic design algorithm, which realized the automatic transform of scale and sheet specification based on given sheet parameters.
