(author)The growing recognition and influence of the ISO 19152:2012 Land Administration Domain Model (LADM), is revealed by the multiple country profiles that have been developed based on the standard in various jurisdictions across the world. The ongoing revision of the LADM Edition I, initiates discussions related to the development of country...journal article 2021

Alattas, A.F.M. (author), Kalogianni, E. (author), Alzahrani, Thamer (author), Zlatanova, Sisi (author), van Oosterom, P.J.M. (author)This paper presents in detail the legislation and regulation related to the use and ownership of building complexes with multiple units (apartments, condominiums) in Saudi Arabia for the 3D registration of the legal spaces. The 3D Land Administration Domain Model (LADM)country profile for Saudi Arabia must be able to represent the identified...journal article 2021

Kitsakis, Dimitrios (author), Kalogianni, E. (author), Dimopoulou, Efi (author), Zevenbergen, Jaap (author), van Oosterom, P.J.M. (author)Intense exploitation of land in the vertical direction has brought up complex legal relations between different types of spatial units with various characteristics (e.g., land, marine, air, underground parcels, and infrastructure objects). Therefore, the use of 3D models is required to clearly represent real property and associated Rights,...conference paper 2021

van Oosterom, P.J.M. (author), Broekhuizen, Marjan (author), Kalogianni, E. (author)The growth of cities and the pressure on land worldwide leads to more complex and multilevel structures with different space interrelations. For the registration of complex spaces mostly 2D Land Administration Systems (LAS) are used, while a representation of space in 3D could provide a clearer insight. Concurrently, technological advancements...conference paper 2021

Kara, A. (author), van Oosterom, P.J.M. (author), Kathmann, Ruud (author), Lemmen, Christiaan (author)The timely and effective dissemination of property values is an essential part of a transparent and efficient property valuation system as property values are required in several land administration processes, such as land acquisition, taxation, transaction, consolidation, readjustment and transformation. In the last decade, a web-based data...conference paper 2021

Ramlakhan, R.J.K. (author), Kalogianni, E. (author), van Oosterom, P.J.M. (author)Two dimensional (2D) Land Administration Systems (LASs) do not adequately represent 3D underground objects. It is not easy to identify the owners of these objects and the relations between objects below and above the surface are not explicitly provided. A 3D LAS can however facilitate a better understanding, as well as a more efficient...conference paper 2021

Thompson, R.J. (author), van Oosterom, P.J.M. (author)The prime purpose of Cadastral data – whether in the form of maps, survey plans or notes, or a digital database is the definitive demarcation of the extent of properties – and can be seen primarily as a decision support facility (“Can a structure be built here?”, “Where can I build a fence?”, “Should I buy this property”?). There are, however...journal article 2021

Liu, H. (author), Thompson, R.J. (author), van Oosterom, P.J.M. (author), Meijers, B.M. (author)Efficient spatial queries are frequently needed to extract useful information from massive nD point clouds. Most previous studies focus on developing solutions for orthogonal window queries, while rarely considering the polytope query. The latter query, which includes the widely adopted polygonal query in 2D, also plays a critical role in...journal article 2021

Balado Frías, J. (author), van Oosterom, P.J.M. (author), Díaz-Vilarino, L. (author), Lorenzo, H. (author)Mathematical morphology is a technique recently applied directly for point cloud data. Its working principle is based on the removal and addition of points from an auxiliary point cloud that acts as a structuring element. However, in certain applications within a more complex process, these changes to the original data represent an...journal article 2021

Balado Frías, J. (author), van Oosterom, P.J.M. (author), Díaz-Vilarino, L. (author), Arias, P. (author)Although point clouds are characterized as a type of unstructured data, timestamp attribute can structure point clouds into scanlines and shape them into a time signal. The present work studies the transformation of the street point cloud into a time signal based on the Z component for the semantic segmentation using Long Short-Term Memory ...journal article 2021

Balado Frías, J. (author), Soilán, M. (author), Díaz-Vilarino, L. (author), van Oosterom, P.J.M. (author)Traffic signs are one of the most relevant road assets for driving, as the safety of drivers depends to a great extent on their correct location. In this paper two methods are compared for the segmentation of the sign and the pole supporting it. Both methods are based on the morphological opening to identify the sign points, the first one...journal article 2021

(author)Governments use flood maps for city planning and disaster management to protect people and assets. Flood risk mapping projects carried out for these purposes generate a huge amount of modelling results. Previously, data submitted are highly condensed products such as typical flood inundation maps and tables for loss analysis. Original...journal article 2021

Peng, D.L. (author), Meijers, B.M. (author), van Oosterom, P.J.M. (author)When users zoom out on a digital map, some area objects become too tiny to be seen, resulting in visual clutters. To avoid this problem, the relatively unimportant areas should be merged with their neighbors to form larger<br/>areas. In order to provide small and smooth changes so that users can easily keep their contexts, we merge a pair of...conference paper 2020

The maps of the comparer can contain multiple layers, and each of them can be a multi-scale layer<br/>or a vario-scale layer. We enhance the comparer’s visual analytical ability by developing more functionalities,...conference paper 2020
