面向对象存储的地图整饰技术

Map Decoration Techniques for Object-oriented Storage

针对诸多GIS平台地图整饰功能存在自动化程度不高、整饰元素编辑不灵活、与地图数据分离等问题,依据规范标准对地图整饰元素进行分类,以面向对象的存储形式设计地图整饰数据模型,分析地图整饰自动化布局过程,基于制图表达机制和ArcGIS Object(简称“AO”)二次开发实现地图整饰功能插件。该技术可在不同比例尺的地图制图项目中应用,大大提高了制图效率。

In view of the problems such as low automation,inflexible editing of decoration elements and separation from map data in many GIS platforms,map decoration elements are classified according to standard,map decoration data model is designed in object-oriented storage form,map decoration automation layout process is analyzed,based on cartographic representation mechanism and ArcGIS Object(referred to as"AO")secondary development to achieve map decoration function plug-in.This technology can be used in different scales of cartographic projects,greatly improving cartographic efficiency.
