No full textAdministration questionnaires. The last FIG questionnaire 2022-2026 was just analysed and the FIG working week 2023 (Kalogianni et al. 2023, and in that paper the creation or update, organization and initial analysis of the results from the 4th FIG 3D Land Administration Questionnaire, as an activity of the FIG Working Group 3D Land Administration 2022-2026 was presented. By sharing this information among the countries/ jurisdictions, a comprehensive inventory will be created. It is expected that cooperation will improve, by learning from the different countries and jurisdictions, to support future developments in the field of 3D land administration. It is noted that, as LADM is finding increasing recognition (Kalogianni et al., 2021), it has been further incorporated into the various sections of the questionnaire. The completed questionnaires, per country are fully available via the participants’ page of the 3D Land Administration Working Group website. The responses have been analyzed and reported in various publications (van Oosterom et al. 2011, van Oosterom et al. 2014 and Shnaidman et al., 2019), while the initial analysis of the 4th Questionnaire has been recently presented by Kalogianni et al. (2023). This paper aims to provide an overview of the developments and plans from the initial questionnaire in 2010, till the future plans for 2026, based on the analyses that have been previously carried out (van Oosterom et al. 2011, van Oosterom et al. 2014 and Shnaidman et al., 2019) and highlighting the results of the analysis from the latest questionnaire. The initial results from the latest questionnaire have been presented by Kalogianni et al. (2023), providing the main outcome from the current status (December 2022), while highlighting the priority axes till 2026 related to the developments of 3D LAS. What is more, an assessment rubric is developed by the team that prepares and analyses the questionnaires, that is actually a scoring of the responses in the various sections of the four (4) questionnaires This assessment process is the first time that is being carried out and it is executed for eight (8) countries and presented in this paper.Digital Technologie

3D Cadastral Lifecycle: An Information Delivery Manual ISO 29481 for 3D Data Extraction from the Building Permit Application Process
No full textThe lifecycle of a 3D cadastral spatial unit and its associated rights, restrictions and responsibilities is made up of many different parts and substages (Van Oosterom 2013). Onepart could be the extraction of 3D data from building permit application process. This paper looks at how this process could be coordinated with a number of other processes and the 3D data used for a variety of purposes including testing conformance to building regulations, rates assessment, inclusion in a national topographic map and asset management. Anassociated use case narrows the scope and illustrates how software which uses the Design and Engineering Methodology for Organisations (DEMO) (Dietz 2006) as reference can be used to facilitate this process.OLD Department of GIS Technolog
INTERLIS 3 developments with 3D data types and better constraint support for 3D Cadastres
No full textINTERLIS is an object relational modelling language and a Swiss national standard used to model and exchange cadastre data in a system neutral form. While INTERLIS was invented in Switzerland 30 years ago and used for over 25 years, in recent years the language has been applied also in many international projects founded by the Swiss government (ie. Azerbaijan, Belarus, Colombia, Georgia, Kosovo, etc.). One notable international development is the description of ISO 19152 LADM in the INTERLIS language, therefore enabling the use of all INTERLIS compatible tools (ie. UML/INTERLIS-Editor, compiler, data validation tools, data translation and schema generation) for LADM. The current version 2.4 of INTERLIS already supports geometric data types in 3D space (i.e. point, polyline, polygon). But for some future applications (i.e. 3D cadastres or BIM) some real 3D primitives (i.e. 3D volumetric type) and 3D constraints are still missing. Further, also topological structures for 2D and 3D space partitions are being investigated. For this reason it is planned to release a draft standard version of INTERLIS 3 which includes all missing types and functions by the end of 2018. INTERLIS 3 will also be proposed as an international standard. This paper describes the new features of the INTERLIS 3 language and how those new features can be applied to 3D cadastres, BIM and Smart Cities to solve real world problems.OLD Department of GIS Technolog
Validity of Mixed 2D and 3D Cadastral Parcels in the Land Administration Domain Model
No full textIn the move towards a 3D Cadastre, many jurisdictions are considering a hybrid 2D/3D database as either a stage of development or as a target in itself (van Oosterom, Stoter, Ploeger, Thompson and Karki 2011). The Land Administration Domain Model (LADM), which is the underlying model for the ISO 19152 standard assists in this approach by defining a data structure which allows a relatively seamless mixing of 2D and 3D “spatial units” (Lemmen, Van Oosterom, Thompson, Hespanha and Uitermark 2010). This standard is in its final stages of approval (Lemmen, Uitermark and van Oosterom 2012). For the purpose of this paper, there is no important distinction to be made between “parcels” “lots” or “spatial units”, since it is only the spatial aspects (topology and geometry) that are being considered, so the term “parcel” will be used to mean the extent of land or space being considered.OTB ResearchOTB Research Institute for the Built Environmen
3D Cadastre and LADM - Needs and Expectations towards LADM Revision
No full textThe last decade, significant progress has been made in advancing the concept of 3D Cadastre and related technologies to facilitate its realisation. There are many examples of partial implementation and prototypes of 3D parcels registration around the world as stated by Kitsakis et al (2016) and Dimopoulou et al (2016) regarding selected countries. While standardisation in the land administration domain extends to 3D and even 4D representations, currently, there is no country that has a fully operational 3D Cadastre supporting all stages of the registration and dissemination (Van Oosterom et al, 2014). In the context of 3D Cadastre developments worldwide, the Land Administration Domain Model (LADM), ISO 19152, outlines the foundations for a 3D Cadastre and becomes one of the best candidates for unambiguously representing 3D Rights, Restrictions and Responsibilities (Kalogianni et al, 2017).The spatial development life cycle of an object begins outside the cadastral registration cycle and has a direct impact on how a specific development application is processed. Thus, in considering the changes required to allow a jurisdiction to register 3D objects, it is important to note the sphere of influence that could have an impact on 3D registration. These include multiple stakeholders and processes, which generate different user needs, as addressed at the previous section and also new opportunities that could be addressed on the current LADM version.To this purpose, this paper explores the needs and prospects towards further 3D modelling of the present LADM version, as derived by the current LADM experience in various countries worldwide in the context of the full spatial development cycle. Nevertheless, over the last few years the number of jurisdictions that are developing LADM-based country profiles,prototype systems and undertaking pilots using various physical models and data formats to achieve LADM implementation in the context of 3D Cadastre has become more significant.Those approaches can be mainly categorised as “fully operational” implementations and “partly-operational” implementations focusing on different aspects of 3D cadastre development cycle; e.g. submission of 3D survey plans, prototype stage; implementations that focus on visualisation, implementations that focus on constraints and validation rules, etc. Finally, within this context, this paper examines how current LADM version can efficiently meet the needs stated above and update user requirements for LADM in the context of the upcoming revision.OLD Department of GIS Technolog
Designing Open Spatial Information Infrastructure to Support 3D Urban Planning in Jakarta Smart City
No full textLand administration is essential for urban planning and Spatial Information Infrastructure (SII). Interoperability of land administration and spatial planning will determine the success of SII utilization. This information should be accessible to all member of SII, including businesses and the community. This article proposes spatial planning information as an extension of the Land Administration Domain Model (LADM), the ISO 19152:2012 in order to support spatial planning. The relevance of spatial planning information to be included into LADM is integral to Land Administration System (LAS) development. 3D Spatial planning along with 3D land administration (LA) will provide a complete scene for land tenure, land valuation, land use, and land development to support sustainable development initiatives. Further, the spatial planning extension will contribute to support the UN member countries in obtaining indicators in the Sustainable Development Goals (SDGs) by improving interoperability and by integrating right, restrictions, and responsibilities (RRR) from spatial planning and LA which are often resulted from separate processes by different parties.OLD Department of GIS TechnologyOLD Geo-information and Land Developmen
FIG publication 3D Cadastres Best Practices
No full textAt the end the two most recent 4-year terms (2010-2014 and 2014-2018) of the joint commission 3 and commission 7 FIG Working Group on 3D Cadastres, it was decided to collect the best known practices in a single FIG publication. Key authors were invited to lead a chapter on one of the following topics:- Chapter 1 Legal foundations (Dimitrios Kitsakis),- Chapter 2 Initial Registration of 3D Parcels (Efi Dimopoulou),- Chapter 3 3D Cadastral Information Modelling (Peter van Oosterom),- Chapter 4 3D Spatial DBMS for 3D Cadastres (Karel Janečka), and- Chapter 5 Visualization and New Opportunities (Jacynthe Pouliot).The mentioned lead authors have each teamed-up with a group of authors to produce their chapters. A lot of inspiration was found in the earlier 3D Cadastres activities of FIG, such as the various 3D Cadastres workshops, the two 3D Cadastres questionnaires, and the presentations and publications at the 3D Cadastres sessions at every FIG Working Week and Congress. The results is a quite extensive FIG publication of about 250 pages, which has been language checked by native English speakers. The publication is further completed with a foreword by the current FIG president Chryssy Potsiou, and introduction by the editor Peter van Oosterom and other front and back materials.Based on this long version also a shorter version is produced (about 80 pages). The short version will become available as FIG publication both in hard-copy (paper) and soft-copy (pdf online). The long version will only be published in soft-copy form and in the style of the FIG proceedings.Both versions are (expected to be) available at the FIG congress 2018 in Istanbul, Turkey. Every chapter will be shortly introduced by one of the authors at the FIG congress 2018.OLD Department of GIS Technolog

Usability testing of a web-based 3D Cadastral visualization system
No full textMany countries are extending their cadastral visualization systems in the third dimension. The reason for this stems from the increasing complexity of contemporary cities, the growing 3D approach in other fields (including 3D spatial data acquisition, spatial data processing and visualization), which made 3D cadastre technologically feasible, and the need to overcome the issues of 2D visualization. The visualization of cadastral parcels in 3D is a challenge, since legal boundaries are, in many cases, invisible in the real world; so how can we properly represent something that is not visible to our eyes? This paper results from research that looks into problems of occlusion and ambiguous perception (in terms of position, size and shape) of objects in the context of 3D cadastre visualization. The exploration of specific interaction techniques is essential to overcome these issues.The aim of this paper is to provide ’lessons learned’ resulting from the implementation of a 3D cadastre prototype that was built with the specific goal of trying out several visualization options of 3D cadastral information in a web environment. A usability test was carried out to obtain feedback from different groups of users. Usability is meant in terms of effectiveness and efficiency of the system and users’ satisfaction. The test users were subdivided into groups according to different professional domains and expertise. During the test, the users are asked to perform a series of tasks typical of cadastral systems. Each task is accompanied by a description to give the users some context. Then, each user is asked to answer a questionnaire about his or her experience. The results are used to extract general feedback. The outcome of the usability test is crucial to point out the detected limitations in this early stage of the prototype development. Design changes can then be made according to the feedback of the test users.OLD Department of GIS Technolog
