Francesca Noardo works on harmonization and integration of open standards to represent high level of detail buildings in maps, in order to foster interoperability between different application fields: the ones centered on the building itself and the ones focused on the study and management of the city.

The GeoBIM project
While the GIS and the BIM domains overlap when the modelling of cities is concerned, each domain retains its own focus and has its own characteristics. The BIM domain focuses on information about the design and construction of building sites, and thus has very detailed and semantically rich information about all the physical elements that comprise an individual building as it is designed or built. Their semantics is based on the IFC Standard. Meanwhile, GIS describe information about the environment as captured at different points in time, thus having less detailed but regularly updated datasets covering wide regions. This is instead based on the CityGML standard data model.

The GeoBIM project works on an interface to process complex architectural IFC models in an automated fashion, performing automated tests on them and converting them to CityGML, in order to automatically analyze the IFC models in their context and update the CityGML city maps, enriching them with high level-of-detail information.

What does this mean for the city?
Due to the overlap in the features modelled in both domains as well as their differing strengths and weaknesses, it is widely acknowledged that the integration of data from both domains is beneficial and a crucial step forward for future 3D city modelling. This integration can avoid unnecessary efforts in redundant modelling and allow for new data flows in both directions and new applications. In this way, more detailed BIM data can feed more general GIS data and GIS data can provide the context that is usually missing in BIM data. By pursuing the integration of GIS and BIM data, many new possibilities appear: with contextual GIS information, BIM methodologies can be better applied to infrastructural works; more detailed 3D city models can be built by reusing BIM data; smart city concepts can perform integrated reasoning on terrain, buildings and city infrastructure; and spatial analyses can support multiple levels of detail and the complete life cycles of objects.

Yet, the disciplines of GIS and BIM are disconnected by their modelling paradigms, software tools and open standards. Consequently, GIS and BIM datasets differ fundamentally with respect to their semantics, geometry and level of detail, and because of the different modelling approach of both, there is not one optimal nor uniform conversion between the information models. It is still very hard to share 3D information among different users throughout the life cycle of urban and environmental processes, i.e. from plan, design and construction to maintenance. Moreover, most of the research so far has focused on the semantic aspects of GIS-BIM integration (e.g. mapping equivalent types), leaving the difficult task of geometric processing on the background. Solving these issues will permit the integration of the two kind of models with great advantage for the city.

Bio
Francesca Noardo has a Master degree in Architecture (Restoration and Promotion) taken at the Politecnico di Torino (Italy) (2012), where she also obtained her Ph.D. degree in Cultural Heritage (2016), developed in the geomatics research field. From 2013 to 2018, she held a research grant in the Politecnico di Torino, Department of Engineering of Environment, Infrastructures and Land, dealing with geomatics themes. In particular, her main interests are 3D survey techniques and the management of cartographic and 3D geometric data through Geographical Information Systems. Her research was especially directed at the use of standard data models and open technologies to archive semantic information in 3D digital maps. She is now Secretary in the Working Group “WG IV/2: Ontologies, Semantics, and Knowledge Representation for Geospatial Information” of the International Society of Photogrammetry and Remote Sensing (ISPRS).
