Powałka, Leon (author), Poon, Chris (author), Xia, Yitong (author), Meines, Siebren (author), Yan, Lan (author), Cai, Yuduan (author), Stavropoulou, G. (author), Dukai, B. (author), Ledoux, H. (author)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 ...conference paper 2024

Hendrickx, G.G. (author), Kranenburg, W.M. (author), Antolínez, José A. Á. (author), Huismans, Y. (author), Aarninkhof, S.G.J. (author), Herman, P.M.J. (author)Estuaries are among the most densely populated and heavily utilised regions in the world, where crucial functions – e.g., freshwater availability and water safety – strongly relate to the natural dynamics of the system. When developing nature-based solutions to safeguard these essential functions, a thorough understanding of estuarine...journal article 2023

Therias, Adele (author), Theodoridou, Eleni (author), PAPADIMITRIOU, CHRYSANTHI (author), Visser, Fabian (author), Zhang, Fengyan (author), Panagiotidou, Ioanna (author)Currently more than 4 billion people live in urban areas around the globe, a trend that is expected to be increased in the upcoming years. While urbanisation provides the space for innovation and new opportunities, in the meantime physical, technical and social challenges are rising and the cities’ vulnerability is increasing. A tool to tackle...student report 2022

Mohd Hanafi, Faraliyana (author), Hassan, Muhammad Imzan (author), Rashidan, Hanis (author), Abdul Rahman, Alias (author)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...conference paper 2022

Huizer, Rick (author)3D modeling techniques can be used to automate processes such as damage assessment in aircraft engines. Aircraft engines often have shiny and non-textured surfaces, where these modeling techniques often have poor performance. This paper gives more insight into the performance of interest detection/matching algorithms on shiny and non-textured...bachelor thesis 2021

Methorst, Ard-Jan (author)In the Netherlands dikes are assessed on piping using the model developed by Sellmeijer. This model is calibrated on experiments with permeable, homogeneous, fluvial sand with no fines and covered by an impermeable cohesive layer. In tidal areas, however, the sand deposits are strongly heterogenous, contain fines and are influenced by...master thesis 2020

Ledoux, H. (author)IndoorGML datasets allow us to represent both (1) the geometry of the interior of a building, which is subdivided into <i>cells</i> (eg rooms, corridors, staircases); and (2) the navigation graph between these cells, which also acts as a mechanism to store the topological relationships between the cells. To be used in applications such as...journal article 2020

(author), Stoter, J.E. (author)As in many countries, in The Netherlands governmental organisations are acquiring 3D city models to support their public tasks. However, this is still being done within individual organisation, resulting in differences in 3D city models within one country and sometimes covering the same area: i.e. differences in data structure, height...journal article 2020

Moraal, Rainier (author)Currently wind turbines are a popular source of renewable energy. Royal HaskoningDHV designs foundations for these turbines. Design optimization of these foundations becomes more and more important due to the growing demand for renewable energy, the development of increasingly large wind turbines and intensification of competition. Design...master thesis 2019

Tekavec, Jernej (author), Lisec, Anka (author)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...conference paper 2018

Khoshelham, K. (author), Díaz-Vilarino, L. (author), Peter, M. (author), Kang, Z. (author), Acharya, D. (author)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...conference paper 2017

Yan, J. (author), Grasso, N. (author), Zlatanova, S. (author), Braggaar, R.C. (author), Marx, D.B. (author)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,...conference paper 2017

Ukrainczyk, N. (author), Koenders, E.A.B. (author)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...conference paper 2014

Guerrero, J.M. (author), Zlatanova, S. (author), Meijers, B.M. (author)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...conference paper 2013

Bisdom, K. (author)The main challenge of naturally fractured reservoirs (NFRs) is understanding how fractures behave in the subsurface outside the radius of influence of wells. Fractured outcrop analogues provide geological concepts that can be used to extrapolate fracture data outside the well control. Numerous methods for studying fractured outcrops are...master thesis 2011
