【摘要】 目前Adobe Illustrator环境下的地图制图中,地图更新时需要对制图区域内的地图要素进行全量更新制图,费时费力。本文提出了一种基于基态地图表达结果的自动化增量式更新制图方法。该方法提出了增量更新模型,根据快照差提取增量信息,结合要素语义分类区分增量信息,实现了增量信息的符号化,并解决了更新过程中产生的图形冲突。采用该方法更新地图,不但大大提高了地图更新效率,还能合理地处理增量更新要素和基态地图要素的关系以及要素冲突。该方法已应用于Illustrator的自动化制图插件系统中,效果较好。更多还原

【Abstract】 At present, in the Adobe Illustrator environment for map production, it is time-consuming and laborious to update all map elements in the mapping area during map updates. This article proposes an automated incremental updating cartographic method based on the result of the original map publications. This method proposes an incremental updating model that extracts incremental information based on snapshot differences, combines element semantic classification to distinguish incremental information, achieves symbolization of incremental information, and solves graphic conflicts that arise during the updating process. By using this method to update maps, it can not only greatly improve the efficiency of map updates, but also handle the relationship and conflicts between incremental updating elements and elements in the original map in a reasonable manner. This method has been applied to the automated cartographic plugin system in Illustrator with good results.更多还原
