Detailed Streetspace Modelling for Multiple Applications: Discussions on the Proposed CityGML 3.0 Transportation Model

Abstract: In the context of smart cities and digital twins, three-dimensional semantic city models are increasingly used for the analyses of large urban areas. While the representation of buildings, terrain, and vegetation has become standard for most city models, detailed spatio-semantic representations of streetspace have played a minor role so far. This is now changing (1) because of data availability, and (2) because recent and emerging applications require having detailed data about the streetspace. The upcoming ve… Show more

“…For instance, for mobility analysis at the district scale, we do need precise location and parameters for building and parking lots access, surface calculations for pedestrians' areas, road and bike lanes but also a linear description of users' routes for distance calculation in agentbased simulations (the lines being generalized from traffic surfaces in a GIS environment). The need for both surface and linear description of roads has also been taken into account in the latest development in CityGML (Beil et al, 2020). This need for entities in various LODs in the design phase raises issues for CIM modelling and calls for a precise description of needs for specific uses.…”

“…Real-world objects are modelled in a hierarchical structure and segmented by thematic modules. These include models of buildings, ter-rain, vegetation, or the streetspace (Beil et al, 2020). Semantic capabilities of 3D city models in combination with geometrically highly detailed point cloud data have great potential for several applications.…”

“…Normal practices utilize LiDAR 360, AutoCAD Revit, Blender and FME Safe software to construct the 3D LoD models according to the user's operation requirements. For example, for spatial mapping, [12] and [13] utilize FME software to convert multiple sources of datasets to construct 3D CityGML LoD models. [14] also integrates various data sources in FME to produce the CityGML model for urban flood management.…”
