Abstract: 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.
