“…Since CityGML specifications do not provide information about generating ADEs with UML, the procedure to obtain the 3D geo-data model from TRKBIS.BI builds on the work of Van den Brink et al (2013). The model driven framework proposed by 3D Pilot in the Netherlands is the best practice for applying CityGML ADE mechanism in UML.…”

This paper presents the generation of the 3D national geo-data model of Turkey, which is compatible with the international OGC CityGML Encoding Standard. We prepare an ADE named CityGML-TRKBIS that is produced by extending existing thematic modules of CityGML according to TRKBIS needs. All thematic data groups in TRKBIS geo-data model have been remodeled in order to generate the national large scale 3D geodata model for Turkey. Within the concept of reference model-driven framework for modelling CityGML ADEs in UML, the first step is conceptual mapping between CityGML and national information model. To test all stages of the framework for Urban GIS Turkey, Building data theme is mapped with CityGML-Building thematic model. All classes, attributes, code lists and code list values of the TRKBIS is tried to be mapped with related CityGML concept. New classes, attributes and code list values that will be added to CityGML Building model are determined based on this conceptual mapping. Finally the new model for CityGML-TRKBIS.BI is established in UML with subclassing of the related CityGML classes. This study provides new insights into 3D applications in Turkey. The generated 3D geo-data model for building thematic class will be used as a common exchange format that meets 2D, 2.5D and 3D implementation needs at national level.

“…As it can be observed from the CityGML specifications and the related scientific literature (for instance, among many, Gröger and Plümer [2012], Kolbe [2008], Kolbe et al [2008], Van den Brink et al [2013a], Biljecki et al [2016b]), the vast majority of the efforts have been spent on developing the concepts and the data model. In our opinion, very little attention has been paid to deriving a usable exchange format.…”

Full details of the project: https://cityjson.orgThe international standard CityGML is both a data model and an exchange format to store digital 3D models of cities. While the data model is used by several cities, companies, and governments, in this paper we argue that its XML-based exchange format has several drawbacks. These drawbacks mean that it is difficult for developers to implement parsers for CityGML, and that practitioners have, as a consequence, to convert their data to other formats if they want to exchange them with others. We present CityJSON, a new JSON-based exchange format for the CityGML data model (version 2.0.0). CityJSON was designed with programmers in mind, so that software and APIs supporting it can be quickly built. It was also designed to be compact (a compression factor of around six with real-world datasets), and to be friendly for web and mobile development. We argue that it is considerably easier to use than the CityGML format, both for reading and for creating datasets. We discuss in this paper the main features of CityJSON, briefly present the different software packages to parse/view/edit/create files (including one to automatically convert between the JSON and GML encodings), analyse how real-world datasets compare to those of CityGML, and we also introduce Extensions, which allow us to extend the core data model in a documented manner.

“…Thirdly, a number of standards and data formats for 3D modelling and visualization of buildings and cities have been developed, e.g. CityGML [4,5]; however, these models are often not used in planning and operation, partly because of problems with interoperability and partly due to the efforts to keep the models up to date [6].…”

Access to data on built environment databases makes nowadays possible generating models of the urban spaces to facilitate visualization and analysis of information and synthesize it in sustainability indicators to support urban planning decisions. Life Cycle Assessment (LCA) can greatly benefit from this wealth of potentially available information. The use of LCA data in models developed in Building Information Modelling (BIM) platforms is likely to facilitate the implementation of quantitative environmental assessment in the construction field and their extension, from the building to the city level. Within sustainable urban planning and management, also Nature-Based Solutions (NBS) play a potentially important role, although benefits, co-benefits and costs associated with NBS projects still remain not sufficiently understood. All those aspects have been discussed via the presentation of case studies, proofs of concept and experts' visions within this session.
