基于AOI思想的电子地形略图制作方法研究

Study on Producing Method of Electronic Topographic Sketch Map Based on the AOI

利用相同的矢量数据动态生成详略程度不同的电子地图，从而满足不同用户的需求，是目前制图者研究电子地图制图的难点。由于电子地图自动生成技术尚未成熟，利用人机交互的方式制作电子地图逐渐成为研究方向之一。本文针对电子地形略图的特点，对地形要素的处理办法进行了阐述，对其在制作过程中的制作要求、交互式综合和制作流程进行了归纳说明，并对电子地形略图制作系统的功能和系统架构分别进行了描述和设计，为电子地形略图制作系统的开发提供借鉴。

It is difficuh for cartographers using the same vector data to produce electronic maps with different details to meet the needs of different users, when cartographers study the cartography of electronic map at present Because the technology of electronic map automatic producing has not yet be mature, it is one of research directions to produce electronic maps in human - computer interactive way. Considering the characteristics of the electronic topo- graphic sketch map, this paper describes the method dealing with terrain elements, and illustrates the requirements and workflow of producing the map and introduces the interactive way used in the procedure. Finally the paper describes the system functions and system framework
