“…To overcome this, both CityGML version 2.0 and 3.0 allow for schema extensions to include additional information, either by using generic city objects and attributes, or by creating an Application Domain Extension (ADE). The use of an ADE seems to be the most commonly used technique for extending CityGML and have been used in many different areas [4,[23][24][25][26]. An ADE is created as a new schema with its own namespace and the relevant CityGML classes are imported.…”

The aim of this paper is to present a proposal for a national building standard in Sweden. We define requirements for the proposed standard, e.g., it should support development of 3D city models, connect to building information models (BIM) and national registers and be based on a national classification system for the urban environment. Based on these requirements we develop an Application Domain Extension (ADE) of the building model in the proposed CityGML 3.0 standard denoted CityGML Sve-Test. CityGML 3.0 includes several new features of interest, e.g., the space concept, enhanced possibilities to convert data, and to link to other standards. In our study we create test data according to CityGML Sve-Test and evaluate it against the requirements. It is shown that BIM models (in Industry Foundation Classes, IFC, format) can be converted to CityGML Sve-Test and that a classification system facilitates this conversion. The CityGML Sve-Test dataset can be used to increase the automation level in building permissions checking and a related study shows that CityGML 3.0 has capabilities to link to legal information and be a base for 3D cadastral index maps. Based on our experience, we suggest that the national building standard should conform to international standards and, if possible, include a classification system. The exchange format (GML, JSON etc.) might change, but to be based on a standardized data model ensures harmonized structures and concepts.

“…Furthermore, these extensions are essentially 'trial balloons' and are not official standards. They could be developed by anyone using different naming conventions and different geometric and semantic notations [11]. Problems related to data interoperability between IFC and CityGML would still exist.…”

LandInfra is a relatively new open standard for modelling and representing land and infrastructure features. As it overlaps with other open standards in BIM (IFC) and 3D GIS (CityGML), it has been recognised as a potential candidate to bridge the gap between the two domains. However, the knowledge of this standard in both communities is low, and there are still no publications which fully explore LandInfra and its possibilities for integrated BIM-GIS applications. In this paper, we review the LandInfra conceptual model and its GML encoding InfraGML, provide a detailed comparison of it with respect to CityGML and IFC, and investigate a few potential use cases where LandInfra and InfraGML are useful for BIM-GIS applications.

“…The output is a CityGML file with LOD1 building objects. The CityGML file can be downloaded by the user directly, or easily integrated in a more structured framework that imports in more robust database systems such as Postgresql supporting further extensibility that is inherent to the CityGML model (Biljecki et al, 2018). Has mentioned, LOD1 is extracted from cartography, but higher levels can be reached if other sources are used, such as LiDAR data or derived products (digital terrain and surface models).…”

Abstract. The paper deals with the general presentation of the Urban GEO BIG DATA, a collaborative acentric and distributed Free and Open Source (FOS) platform consisting of several components: local data nodes for data and related service Web deploy; a visualization node for data fruition; a catalog node for data discovery; a CityGML modeler; data-rich viewers based on virtual globes; an INSPIRE metadata management system enriched with quality indicators for each dataset.Three use cases in five Italian cities (Turin, Milan, Padua, Rome, and Naples) are examined: 1) urban mobility; 2) land cover and soil consumption at different resolutions; 3) displacement time series. Besides the case studies, the architecture of the system and its components will be presented.
