Urban spatial structure: an interaction between employment and built-up volumes

Abstract

This paper employs socioeconomic and remote sensing data to develop a novel approach to analysing the morphological urban spatial structure in select German city-regions. Furthermore, the suggested multidimensional procedure facilitates the analysis of the implications of different urban spatial structures in terms of physical urban form. All analyses are conducted on the spatial scale of 1 km² grid cells to allow for spatially detailed results and to account for intra-municipality differences in the urban spatial structures in the study regions. The results indicate fundamental differences among the study regions’ distribution of employees and built-up volumes and, as a result, among their urban spatial structures. Both employees and built-up volumes are found to be highly spatially clustered primarily within the core cities but with notable exceptions, which thus qualifies the regions as polycentric. This finding is consistent with prior research but also reveals that built-up volumes can be understood as physical manifestations of proximity advantages to which firms and employees are subject.
