Applying DLM and DCM concepts in a multi-scale data environment

Validation of planar partitions using constrained triangulations

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...

Topologically consistent 3D city models obtained by extrusion

One of the simplest methods to construct a 3D city model is to extrude building footprints to obtain \block-shaped" polyhedra representing buildings. While the method is well-known and easy to implement, if the 2D topological relationships between the footprints are not taken into account, the resulting 3D city models will not necessarily be...

A storage and transfer efficient data structure for variable scale vector data

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...

Shifting fortunes of neighbouring cities

Polycentricity is often conceived to be the product of “a long process of very extended decentralization from big central cities to adjacent smaller ones, old and new” (Hall and Pain, 2006: 3). Accordingly, polycentric spatial development (as a process) is usually identified with a development towards a more balanced distribution of functions...

Extruding building footprints to create topologically consistent 3D city models

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...

Closing the Gap: Territorial Cohesion through Polycentric Development

This article discusses and analyses national polycentric development policies aiming at cohesion. Due to its insertion in the 1999 European Spatial Development Perspective ‘polycentricity’ has become an important concept in discussions on Europe’s territorial and economic development. Its content remains however rather unclear. This paper...

Synergy in polycentric urban regions: Complementarity, organising capacity and critical mass

This thesis focuses on relationships between cities in Polycentric Urban Regions (PURs), which are regions containing proximate but distinct cities that are rather similar in size. A classic example is the Randstad. The extent to which there are synergies between cities in PURs is explored. The author develops theories on synergy in PURs and...
