Smart mobility cannot be supported by smart technologies alone. It has to be supported by geospatial data with navigation lines. Manual methods for creating and updating them are not only costly but also time-consuming. Automatic extraction and updating of geospatial navigation lines from GIS and indoor layout plans are much needed. The navigation path is often stored and conceived as centreline graphs in GIS. However, navigation paths in which the centrelines are located can be considered as a combination of basic navigation polygons. This paper proposed a generic polygonization method that can automatically generate and update navigation centrelines from GIS and BIM. By constructing basic navigation polygons from GIS and decomposing path polygons in street layouts and floor plans from GIS and BIM into basic navigation polygons, indoor and outdoor pedestrian navigation paths and centrelines can be extracted and generated to be used for indoor and outdoor pedestrian navigation.

仅靠智能技术无法支持智能移动。它必须得到带有导航线的地理空间数据的支持。手动创建和更新它们的方法不仅成本高昂，而且耗时。非常需要从 GIS 和室内布局计划中自动提取和更新地理空间导航线。导航路径通常在 GIS 中存储和设计为中心线图。但是，可以将中心线所在的导航路径视为基本导航多边形的组合。本文提出了一种通用的多边形化方法，可以根据GIS和BIM自动生成和更新导航中心线。通过从GIS构建基本导航多边形并将GIS和BIM中街道布局和平面图的路径多边形分解为基本导航多边形，
