Construction method for topological integration of multi-scale datasets supported by a primal-dual data structure

Spatial datasets covering the same area often exist as separate layers, which differ in scale and source. The spatial relations between matching features located at different layers can be retrieved through a computationally demanding process based on geometry and other propertie...

Linking Persistent Scatterers with Urban Features Using LoD2 Building Models

Abstract. Persistent Scatterer Interferometry (PSI) provides valuable information on ground and structural changes, particularly in dynamic urban environments. At the same time, urban digital twins (UDTs), as detailed three-dimensional (3D) representations of cities, are increasi...

Shadow Geometric Analysis Utilising CityGML Models and FME

Abstract. This research presents a methodology for conducting shadow geometric analysis, specifically the shadow boundary in an urban model. Input data include a georeferenced CityGML LoD2 and terrain model. Additional land cover data is used to exclude some parts of the model fr...
