Title:
Spatio-Semantic Comparison of Large 3D City Models in CityGML Using a Graph Database 
Pages contribution:
99-106 
Abstract:
A city may have multiple CityGML documents recorded at different times or surveyed by different users. To analyse the city’s evolution over a given period of time, as well as to update or edit the city model without negating modifications made by other users, it is of utmost importance to first compare, detect and locate spatio-semantic changes between CityGML datasets. This is however difficult due to the fact that CityGML elements belong to a complex hierarchical structure containing multi-lev...    »
