Meijers, B.M. (author), Suba, R. (author), van Oosterom, P.J.M. (author)Processing massive datasets which are not fitting in the main memory of computer is challenging. This is especially true in the case of map generalization, where the relationships between (nearby) features in the map must be considered. In our case, an automated map generalization process runs offline to produce a dataset suitable for...conference paper 2015

Zlatanova, S. (author), van Oosterom, P.J.M. (author), Lee, J (author), Li, Ki-Joune (author), Lemmen, C. H. J. (author)Guidance and security in large public buildings such as airports, museums and shopping malls requires much more information that traditional 2D methods offer. Therefore 3D semantically-reach models have been actively investigated with the aim to gather knowledge about availability and accessibility of spaces. Spaces can be unavailable to...conference paper 2016

Alam, M.N. (author), Coors, V. (author), Zlatanova, S. (author), van Oosterom, P.J.M. (author)In this paper, an analysis of the effect of the various types of resolution involved in photovoltaic potential computation is presented. To calculate solar energy incident on a surface, shadow from surrounding buildings has been considered. The incident energy on a surface has been calculated taking the orientation, tilt and position into...conference paper 2016

Zlatanova, S. (author), Li, Ki-Joune (author), Lemmen, Christiaan (author), van Oosterom, P.J.M. (author)In this paper we investigate the possible synergy between two different but related standards: OGC’s IndoorGML and ISO TC211’s LADM. Both (can) deal with 3D spaces with properties, constraints and associations attached and both can operate with abstract notations of space. But there are also differences, e.g. LADM is a conceptual model, while...conference paper 2016

Kalogianni, Eftychia (author), Dimopoulou, Efi (author), Quak, C.W. (author), van Oosterom, P.J.M. (author)Building Information Models (e.g. BIM, IFC) and virtual 3D city models (e.g. CityGML) are revolutionising the way we manage information about cities. The main focus of such models is on the physical and functional characteristics of urban structures (Aien et al, 2015). On the other hand cadastral data models, (e.g. Land Administration Domain...conference paper 2016

Jaljolie, Ruba (author), van Oosterom, P.J.M. (author), Dalyot, Sagi (author)Following public demand to improve the efficiency and transparency of government administrations, together with the existence of mature technologies and modern urban planning necessities, it is now essential to establish more advanced and comprehensive land management (cadastre) systems. Cadastre systems available today are mostly based on...conference paper 2016

Oldfield, Jennifer (author), van Oosterom, P.J.M. (author), Quak, C.W. (author), Veen, Jeroen van der (author), Beetz, Jakob (author)Much work has already been done on how a 3D Cadastre should best be developed. An inclusive information model, the Land Administration Model (LADM ISO 19152) has been developed to provide an international framework for how this can best be done. While this generic framework encompasses a wide range of eventualities, it does not prescribe the...conference paper 2016

Rovers, A (author), Meijers, B.M. (author), van Oosterom, P.J.M. (author)This paper presents a methodology for using a generic data-driven spatial access method as a communication mechanism for vario-scale data in a server-client setting. As a complete data set is often quite large, it is managed at the server side and supporting different scale levels is important. We show that a generic R-tree like grouping method,...conference paper 2017

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...conference paper 2017
