- The formation and alteration of real property and rights, restrictions and responsibilities are important parts of land administration. Research on the distribution of publications in the three-dimensional (3D) cadastral domain has been in focus as a specialised part of real property research during the last decades. A number of literature surveys on research trends in the domain show a growing number of publications during the last decades. The number of publications have increased considerably within a range of topics, classified into legal, technical, registration and organisational categories of 3D property. The purpose of the research presented here is to contribute to these analyses of the number and thematic distribution of the 3D cadastral domain literature by analysing three aspects: 1) To add to the recent study by including 3D cadastre publications published during 2021 (Paasch and Paulsson, 2021b, Paasch and Paulsson, 2021a); 2) To briefly analyse the classification of 3D cadastre research in technical programmes and proceedings of major conferences focussing, in total or in part, on 3D cadastre. 3) The results are used to contribute to the discussion regarding if the 3D cadastral domain is too diverse today to talk about a single 3D cadastral domain. An input to the discussion of what constitutes a domain is provided from an analysis of another land administration research topic that is often addressed in relation to 3D real property research; the international standard for land administration, the Land Administration Domain Model, LADM, ISO 19152.

Tidskriftsartikel (refereegranskat)abstract
- Multiple Land Administration Domain Model (LADM) related studies have been carried out in two decades. ISO 19152 LADM is an international standard and an abstract, conceptual model covering the land administration domain (including those over land and water and elements above and below the earth's surface). The LADM is considered an important component for managing and developing land administration systems worldwide. In the context of this study's, scientific publications related to LADM are examined to carry out a bibliometric analysis on LADM research from 2012 to 2020. The extent of this investigation is limited to the Scopus database for scientific publications. All databases belong to the most extensive peer-reviewed summary and citation databases. It is noted that this study is based on the same principles as the research published by Paulsson and Paasch (2015), building on existing knowledge and aiming to add value in support to the current development of Edition II of the LADM.In this study, which covers 2012–2020, 175 LADM related scientific publications were found in the Scopus database. When the distribution of publications in journals is examined, Land Use Policy has the most published manuscripts related to ISO 19152 LADM. This analysis considers author identification, type of paper, organisational issues, and bibliometric analysis components. The analysis considered articles, books, and proceedings directly related to the LADM and included in the Scopus database or conference and workshop proceedings. For this, articles and books were selected from the Scopus database. Also, the proceedings were selected from those presented in the International Federation of Surveyors (FIG) events and workshops on LADM. Overall, this paper aims to arrange and present the global scientific production on LADM-based research.

Visualisation of 3D Property Data and Assessment of the Impact of Rendering Attributes

Tidskriftsartikel (refereegranskat)abstract
- Visualisations of 3D cadastral information incorporating both intrinsically spatial andnon-spatial information are examined here. The design of a visualisation prototype islinked to real case 3D property information. In an interview with domain experts, thefunctional and visual features of the prototype are assessed. The choice of renderingattributes was identified as an important aspect for further analysis. A computationalapproach to systematic assessment of the consequences of different graphical designchoices is proposed. This approach incorporates a colour similarity metric, visualsaliency maps, and k-nearest neighbour (kNN) classification to estimate risks ofconfusing or overlooking relevant elements in a visualisation.The results indicate that transparency is not an independent visual variable, as itaffects the apparent colour of 3D objects and makes them inherently more difficult todistinguish. Transparency also influences visual saliency of objects in a scene. Theproposed analytic approach was useful for visualisation design and revealed that theconscious use of graphical attributes, like combinations of colour, transparency andline styles, can improve saliency of objects in a 3D scene.

A BIM-based approach to design a lifecycle 3D property formation process : A Swedish case study

Tidskriftsartikel (refereegranskat)abstract
- 3D property formation has become an important solution to provide a more comprehensive and accurate representation of the property's physical characteristics than traditional 2D property formation. Despite the numerous benefits of the 3D property formation, there is a need for more detailed descriptions of 3D cadastral data delivery between the involved actors to ensure efficient and effective collaboration. In particular, the practical difficulties are when/what related 3D cadastral information and models should be exchanged and stored from/to whom. Therefore, to address these issues, we propose a lifecycle 3D property formation process with four phases by designing an IDM process, which is an international open BIM process standard. In the purpose of forming a Swedish lifecycle 3D property formation process, the IDM process has been applied through organizational, legal and technical aspects, including identifying actors and their roles and values, gathering 3D property formation requirements, defining the data exchange requirements and designing the process map. Moreover, a case study was used to specify the Swedish lifecycle 3D property formation process and information delivery between stakeholders in the IDM. The aim is to facilitate a standardized and unambiguous digital 3D property formation procedure on a national level in order to improve and enhance the digital Swedish Cadastral and Land Administration Systems, but the process is quite generic and could also be applied in other countries.

BIM-based 3D Cadastral Management. Slutrapport för projektet BIM-baserad hantering av 3D-fastighetsinformation
- 2022
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- För 3D-fastighetsförvaltning är huvudsyftet förmågan att utveckla och hantera 3D-fastighetsförvaltning digitalt, holistiskt och hållbart. För att uppnå det har projektet BIM-baserad hantering av 3D-fastighetsinformation haft huvudfokus på hur man kan använda en BIM-ansats i digitaliseringen av 3D fastighetsinformation genom en tvärvetenskaplig metodik. Forskargruppen har bestått av forskare från KTH, Lunds universitet, Högskolan i Gävle och Lantmäteriet samt arbete tillsammans med en referensgrupp från Stockholmsstad och industriföretag. I projektet har två arbetspaket genomförts: Arbetspaket 1 – livscykel för en svensk 3D-fastighetsbildningsprocess och Arbetspaket 2 –fastighetsekosystem. Arbetspaket 1 har utvecklat en BIM-baserad livscykel för en svensk 3D-fastighetsbildningsprocess i form av en IDM-processkarta för att visa hur 3D-fastighetsdata, 2D/3D GIS-data och BIM-modeller skulle kunna delas, utbytas och lagras genom hantering av olika aktörer. Arbetspaket 2 har föreslagit och skapat ett nytt multidisciplinärt nätverk för samarbete–affärsekosystembaserad fastighetsförvaltning och utvidgning till ett bredare ramverk – fastighetsekosystem, som skulle kunna länka policy, aktörer, process, teknik och affärer tillsammans för en bättre och djupare förståelse av hållbar 3D-fastighetsförvaltning ur juridiska, tekniska, registrerings- och organisatoriska perspektiv. Sammantaget visar resultaten att integrationen av BIM och 3D GIS för 3Dregistrering kan ge involverade aktörer nödvändig och korrekt information, kunskap och insikt som förbättrar ekonomiska, miljömässiga och sociala resultat på ett hållbart sätt för både städer och medborgare. Vidare skulle fastighetsekosystemet kunna underlätta policyimplementering, samordna aktörers samarbete, förbättra processeffektiviteten, uppnå teknikintegration och innovation samt skapa värde över multidisciplinära kompletterande bidrag. I slutändan ger författarna rekommendationer från policy-, aktörs-, process-, teknik- och affärsaspekter som på ett holistiskt sätt skulle kunna underlätta digitaliseringen av livscykeln för 3D-fastighetsförvaltning och påskynda utvecklingen av fastighetsekosystemet på ett hållbart sätt. Målgruppen för resultatet av detta projekt är alla som deltar i eller berörs av 3D-fastighetsbildning, både vid nybyggnation och inom befintligt byggnadsbestånd, såsom kommunala och statliga förvaltare, exploatörer, sökande/fastighetsägare, medborgare, politiker, myndigheter och andra organisationer.
