Abstract [en]

The initial geographic information system (GIS) and building information modelling (BIM) are designed and developed independently in order to serve different purposes and use. Within the prolific increase and growing maturity of three-dimensional (3D) technology, both 3D geodata and BIM data can specify semantic data and model 3D buildings that are prominent for the 3D city models and 3D cadastre. 3D geodata can be collected from geodetic surveying methods such as total station, laser scanning and photogrammetry and generate 3D building models by CityGML format for macro analysis on city scale. BIM data has significant advantages in planning, designing, modelling and managing building information, which contains rich details of building elements. Additionally, BIM helps and supports to exchange and share complex information through life-cycle project. Because there are some overlaps between them, the integration of BIM and 3D city models is mutually beneficial for representing comprehensive 3D building models.

This thesis is a summary and compilation of two papers, where one is a review paper published in Journal of Spatial Science, and the other is a research paper currently under review in ISPRS International Journal of Geo-Information. The first paper designed and implemented a methodology to formalize the integration of BIM data into city models (CityGML models) that were generated from BIM data and from ALS/footprint data based on the proposed common modelling guidelines. The geometric results of the CityGML models were compared and evaluated visually and quantitatively. The second paper proposed a general framework for sharing and integrating cadastral information with BIM and 3D GIS together with general requirements. Based on the requirements and framework, the case study focused on how to represent and visualize 3D cadastral boundaries legally and technically by integrating BIM at building level and CityGML at city level. Both the Industry Foundation Classes (IFC) model and the CityGML model were connected to Land Administration Domain Model (LADM) at the conceptual level using Unified Modeling Language (UML) models and on database level.

The findings of the first paper include investigation of BIM data as a qualified source on the geometric aspects in order to satisfy the need for a more rapid update process of 3D city models, and the second paper shows that the proposed framework and requirements perform well for generating 3D cadastral model in the real-world case study.

Abstract [sv]

Det ursprungliga geografiska informationssystemet (GIS) och byggnadsinformationsmodellering (BIM) är utformade och utvecklade oberoende av varandra för att tjäna olika syften och användning. Inom 3D-teknik kan både 3D geodata och BIM-data specificera semantiska data och modellera 3D-byggnader som är framträdande för 3D stadsmodeller och 3D fastighetsregister. 3D-geodata kan samlas in från geodetiska mätningsmetoder som totalstation, laserskanning och fotogrammetri och de kan generera 3D modeller av byggnader i CityGML för makroanalys av städer. BIM-data har betydande fördelar i planering, design, modellering och hantering av byggnadsinformation eftersom det innehåller detaljerade uppgifter om byggelement. Dessutom gör BIM det möjligt att förmedla och analysera komplex information över byggnaders livscykel. Integrationen av BIM- och 3D-stadsmodeller är viktigt för att kunna analysera både byggnader och stad, exempelvis i stadsplanering, byggnadskonstruktion och hållbarhetsanalys.Denna avhandling är en sammanfattning och sammanställning av två artiklar, varav den ena är publicerad i Journal of Spatial Science, och den andra är under granskning i ISPRS International Journal of Geo-Information. Den första artikeln utformade och implementerade en metod för att formalisera integrationen av BIM-data i stadsmodeller (CityGML-modeller) som genererades från BIM-data och flygburen laserskanning/fotavtryck baserat på gemensamma modelleringsriktlinjerna. De geometriska resultaten av CityGML modellerna jämfördes och utvärderades visuellt och kvantitativt. Den andra artikeln föreslog en allmän ram för att dela och integrera fastighets information med BIM och 3D GIS tillsammans med allmänna krav. Baserat på kraven och ramverket så visade en fallstudie på hur man kan representera och visualisera 3D fastighetsgränser juridiskt och tekniskt genom att integrera BIM på byggnadsnivå och CityGML på stadsnivå. Både IFC-modellen och CityGML-modellen kopplades till LADM på konceptuell nivå med hjälp av UML-modeller och på databasnivå.Slutsatserna från den första artikeln inkluderar undersökning av BIM data som en kvalificerad källa på de geometriska aspekterna för att uppfylla behovet av en snabbare uppdateringsprocess av 3D-stadsmodeller, och den andra uppsatsen visar att det föreslagna ramverket och kraven presterar väl för att generera 3D fastighets modeller i den verkliga världen.

Abstract [en]

Airborne Laser Scanning (ALS) is used to acquire three-dimensional(3D) city model data over large areas. However, because of the longALS update cycle, building information models (BIM) could be utilizedto maintain city models. In this study, we designed, implemented, andevaluated a methodology to formalize the integration of BIM data intocity models. CityGML models were created from BIM data and ALS/footprint data based on common modelling guidelines. Both CityGMLbuilding models are modelled in a similar way and the relative differencesbetween the models are on the order of decimetres.

Abstract [en]

The current three-dimensional (3D) property units are in most countries registered using two-dimensional (2D) documentation and textual descriptions. This approach has limitations of representing the actual extent of complicated 3D property units and also to provide an overview of the 3D cadastre in e.g. city centers. To improve the representation and visualization of the 3D cadastre we could utilize 3D digital models. To facilitate this several requirements needs to be considered such as organizations, legal rules, coordinate reference systems and height systems, data standards, geometry and users. In this study, we formulate these requirements and then develop a framework for integration of 3D cadastre and 3D digital models. The basic idea is that cadastral information (stored the in Land Administration Domain Model, LADM) are integrated with Building Information Modelling (BIM) on building level for accurate representation of legal boundaries and with Geographic Information System (GIS) on city level for visualization of 3D cadaster in urban environments. The framework is implemented and evaluated against the requirements in a practical case study in Sweden. The conclusion is that the integration of the cadastral information and BIM/GIS is possible on both conceptual level and data level which will facilitate that organizations dealing with cadastral information (cadastral units), BIM models (architecture, engineering and construction companies) and GIS (surveying units on e.g. municipality level) can exchange information; this facilitates better representation and visualization of 3D cadastral boundaries.
