Diaz, Vitali (author), van Oosterom, P.J.M. (author), Meijers, B.M. (author), Verbree, E. (author), Ahmed, N. (author), Van Lankveld, T. (author)The advantages of using point clouds for change detection analysis include comprehensive spatial and temporal representation, as well as high precision and accuracy in the calculations. These benefits make point clouds a powerful data type for spatio-temporal analysis. Nevertheless, most current change detection methods have been specifically...abstract 2024

Meijers, B.M. (author), Van Oosterom, P.J.M. (author), Quak, C.W. (author)This paper deals with efficient data management of variable scale vector data. Instead of pre-building a collection of data sets on different scales, we create an index structure on the base data set (largest scale data) that enables us to extract a map at exactly the right scale the moment we need it. We present both the classic version of the...book chapter 2009

Ledoux, H. (author), Meijers, B.M. (author)One of the simplest methods to construct a 3D city model is to extrude building footprints, to obtain "block-shaped" buildings. While the method is well-known and easy to implement, if the topological relationships between the footprints are not taken into account, the resulting city models will not necessarily be topologically consistent. As a...book chapter 2009

Stoter, J.E. (author), Ledoux, H. (author), Meijers, B.M. (author), Arroyo Ohori, G.A.K. (author)This paper presents the problem of the current separate treatment of levels of detail in city models. We propose a solution, detail the main principles, and present our initial results on the approach. We conclude with work in progress and explain the benefits of our approach.conference paper 2012

Meijers, B.M. (author), Van Oosterom, P.J.M. (author)This paper introduces the concept of a space-scale partition, which we term the space-scale cube – analogous with the space-time cube (first introduced by Hägerstrand, 1970). We take the view of ‘map generalization is extrusion of 2D data into the third dimension’ (as introduced by Vermeij et al., 2003). An axiomatic approach formalizes the...conference paper 2011

Peters, R.Y. (author), Ledoux, H. (author), Meijers, B.M. (author)Depth-contours are an essential part of any hydrographic chart|a map of a water-body intended for safe ship navigation. Traditionally these were manually drawn by skilled hydrographers from a limited set of surveyed depth measurements. Nowadays this process of map making is shifted towards the digital domain, not in the last place because of the...conference paper 2013

Suba, R. (author), Meijers, B.M. (author), Van Oosterom, P.J.M. (author)This paper focuses on 3D data structures supporting an alternative approach for creating 2D vario-scale maps. The smooth animated zooming functionality have lead us to investigate a volumetric representation of gradually changing vario-scale objects. In this paper, the principle of vario-scale maps with theoretical knowledge about 3D...conference paper 2013

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

Ledoux, H. (author), Meijers, B.M. (author)Planar partitions—full tessellations of the plane into non-overlapping polygons—are frequently used in GIS to model concepts such as land cover, cadastral parcels or administrative boundaries. Since in practice planar partitions are often stored as a set of individual objects (polygons) to which attributes are attached (e.g. stored with a...conference paper 2010

Van Oosterom, P.J.M. (author), Meijers, B.M. (author)This paper presents the first true vario-scale structure for geographic information: a delta in scale leads to a delta in the map (and smaller scale deltas lead to smaller map deltas until and including the infinitesimal small delta) for all scales. The structure is called smooth tGAP and its integrated 2d space and scale representation is...conference paper 2011

Meijers, B.M. (author)In this paper, we will give a description of a design of a fat client and study some implementation issues, to use the tGAP structures for progressive data streaming. This is an experiment to validate the theory of Haunert et al. (2009). Furthermore this theory is extended and a solution is proposed to make the progressive data streaming more...conference paper 2011

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

Suba, R. (author), Meijers, B.M. (author), Van Oosterom, P.J.M. (author)The classical approach for road network generalization consists of producing multiple maps, for a different scale or purpose, from a single detailed data source and quite often roads are represented by line objects. Our target is the generalization of a road network for the whole scale range from large scale, where roads are represented as area...conference paper 2015
