摘　　要：地物、道路、植被和河流等要素是构成地图的基本元素,是地图内容的重要组成部分。而河流等线状要素信息的准确绘制是地图整体架构的良好视觉效果的重要内容。因此,如何能够绘制线条流畅、宽度均匀过渡的几何渐进的河流是自动化制图的一个重要研究方向。为此,本文借助具有强大图文编辑功能的Adobe Illustrator(AI)软件平台来进行地图制图中河流几何渐变的绘制。本文基于等长模型、等差模型以及制图模型,利用AI实现了河流几何渐变的准确绘制。实验结果表明:相对于现有的CorelDRAW等渐变工具,基于AI的河流几何渐变绘制具有更好的视觉效果。Features,roads,vegetation and rivers are the basic elements and important parts of the map,and accurate drawing of linear elements such as rivers is important for the good visual effect of the overall map structure.Therefore,how to draw gradual-change rivers with smooth lines and uniform width is an important research topic in the field of automatic cartography.In this paper,Adobe Illustrator(AI)software platform with powerful graphic editing function is used to draw gradual-change rivers in cartography.This paper uses Adobe Illustrator(AI)to draw gradual-change rivers based on the technical advantages of AI and has achieved accurate gradual-change river drawing based on isometric model,arithmetic model and cartographic model.The experi mental results show that AI-based river geometric gradual-change drawing has better visual effects compared with CorelDRAW-based river drawing methods.
