摘要
在地形图数据建库过程中,如何准确快速地提取建筑物属性是一项重要的任务。本文通过分析建筑物注记内容和使用正则表达式规则,提出了一种快速提取建筑物属性的方法,在C#环境下开发了基于ArcGIS Addin的插件工具,能高效快速地提取地形图中建筑物的属性信息,并在生产实践中验证了其可行性,能大幅度提升工作效率。
In the process of building topographic map data,how to extract building attributes accurately and quickly is an important task.By analyzing the content of building annotations and using regular expression rules,this paper proposes a method for extracting building attributes quickly.A plug-in tool based on ArcGIS addin is developed in C#environment,which can efficiently and quickly extract buildings in topographic maps.The attribute information of the product has been verified in production practice,which can greatly improve work efficiency.
