When it comes to storing 3D city models in a database, the implementation of the CityGML data model can be quite demanding and often results in complicated schemas. As an example, 3DCityDB, a widely used solution, depends on a schema having 66 tables, mapping closely the CityGML architecture. In this paper, we propose an alternative (called ...

This paper describes the use of 3D real property formation at a major construction site in Stockholm, Sweden, project Slussen. Real property formation with complex 3D volumes and numerous real properties and associated rights, restrictions and responsibilities (RRRs) has to be shown with the real properties and RRRs in relation to each other....

This paper focuses on experiences concerning a project aiming at visualisation of three-dimensional (3D) property units in Stockholm, Sweden. The Swedish national registration system, the national real property register, includes a textual description as well as a two-dimensional map, normally consisting of a scan of the legal map document...

The development and widespread adoption of immersive XR applications has led to a renewed interest in representations that are capable of reproducing real-world objects and scenes with high fidelity. Among such representations, point clouds have attracted the interest of industry and academia alike, and new compression solutions have been...

Owing to population growth in Malaysia, there have been significant stratified subsurface and aboveground developments, particularly in densely populated areas, posing a challenge to the current land administration system and the urge to constantly improve. Land Administration Domain Model (LADM) provides a relatively generic spatial...

Developments of legal, institutional and technical aspects in realizing property registration of 3D parcels situated above and below 2D parcels are still evolving in many countries. 3D cadastres have to deal with various institutional/legal gaps and challenging information integration regarding the Rights-Restrictions-Responsibilities (3R) of 2D...

This article focuses on 3D indoor modelling of buildings using cadastral data as an alternative way of indoor spatial data acquisition. Despite the rapid development of indoor spatial data acquisition technology, there are no existing solutions that would enable mass acquisition of indoor data. The main motivation for our research was the...

The rapid economic and social transformation over the last several years, has led to multiple rearrangements regarding the land administration procedures. Vertically growing cities, complex infrastructure, subdivision of three-dimensional (3D) space through several uses and overlapping property rights have increased the demand for establishing...

Automated generation of 3D indoor models from point cloud data has been a topic of intensive research in recent years. While results on various datasets have been reported in literature, a comparison of the performance of different methods has not been possible due to the lack of benchmark datasets and a common evaluation framework. The ISPRS...

Visibility computed from a LiDAR point cloud offers several advantages compared to using a gridded digital height-model. With a higher resolution and detailed information, point cloud data can provide precise analysis as well as an opportunity to avoid the process of generating a surface representation or a solid model. Also a better inclusion...

Three-dimensional modelling plays a vital role in indoor 3D tracking, navigation, guidance and emergency evacuation. Reconstruction of indoor 3D models is still problematic, in part, because indoor spaces provide challenges less-documented than their outdoor counterparts. Challenges include obstacles curtailing image and point cloud capture,...

This paper presents method and first results of a study to quantify and communicate geotechnical risk for highway construction on soft soil and large building pits associated with infrastructural works in the Netherlands. A set of easy-to-read maps will inform the end users, geotechnical consultants at the Dutch Ministry of Infrastructure and...

Valuation of real estate/ properties is in many countries/ cities the basis for fair taxation. The value depends on many aspects, including the physical real world aspects (geometries, material of object as build) and legal/virtual aspects (rights, restrictions, responsibilities, zoning/development plans applicable to the objects spaces)....

Over the last decades, land exploitation is getting more intense in order to satisfy public and private needs of modern societies. The intensification of 3D space exploitation includes complicated rights, restrictions and responsibilities (RRRs) that need to be unambiguously registered. In this direction, the incorporation of 3D aspects of real...

Coupled reactive-transport processes in cementitious materials play a crucial role in the aging process pf building materials. Up to now, the effect of aging on microstructure and evolution of it’s properties, in three dimensions, was studied only by dissolution of certain phases at random locations. In this paper we present a new 3D reactive...

Underground pipelines pose numerous challenges to 3D visualization. Pipes and cables are conceptually simple and narrow objects with clearly defined shapes, spanned over large geographical areas and made of multiple segments. Pipes are usually maintained as linear objects in the databases. However, the visualization of lines in 3D is difficult...

The idea of ‘city’ has now surpassed its physical concept. The emergence of the Internet and the growing development of information and communication technologies (ICT) have changed the behaviour of our society in the past decade and revolutionised the traditional ways of representing space. The classic 2D (floor plans, sections and elevations)...

The aim of this paper is to discuss the role three-dimensional models play in addressing performance issues in virtual reconstructions of the heritage buildings. Heritage visualisation is considered here as a process of representing knowledge about space, time, behaviour, light, and other elements that constitute cultural environments. The...

In this paper a methodology will be presented to investigate and document the constructive characteristics of two raw earth houses: artifacts that belong to the vernacular architecture. The comprehension, analysis and documentation of these architectures presents several problems mainly linked to the impossibility of using a predefined method,...
