Full-text available
The use of urban green spaces (UGS) depends on its quality, which is perceived very differently by diverse socio-demographic groups. In particular, elderly people have special demands on the UGS quality. It is essential to know these demands to create an equitable UGS supply. We present an approach to determining some qualitative aspects and the su...

The increasing density of urban spaces and buildings is undermining public health. To compensate, there is a growing trend towards biophilic design, including at one of the most frequented and highly functional sites: railway stations. Previous studies have confirmed the economic feasibility of station greenery and users' preference for this but al...

The German non-residential building stock is not fully represented in any official statistics, in contrast to residential buildings. This is surprising given the economic significance of this asset and its importance as a source of greenhouse gases. This knowledge gap was closed in the project Research Database Non-residential Buildings. Statistica...

This paper demonstrates an approach to the problem of micro-scale analysis of medical service provision in Germany. Research focuses include estimating population dynamics, mapping access to medical facilities and identifying spatial patterns in medical service provision. We applied the Enhanced Two Step Floating Catchment Area method to quantify c...
Article
21 st century urbanisation features not only the growth of city populations but also the emergence of densification (infilling) as significant trends in urban development. While urban sprawl has long been acknowledged for its adverse effects, understanding densification remains challenging due to inadequate empirical and statistical frameworks. Thi...

Dasymetric mapping is a well-known technique when attempting to refine census data spatially and/or temporally. Existing approaches in micro-level census disaggregation make use of building areas or volumes in the mapping process. In an empirical error comparison it is shown that using additional address data rather than only building footprints or...

Building usage is an important variable in modelling the energetic, material and social properties of a building stock. Gathering this data on large geographical scale, and in the necessary temporal and spatial resolution, that means, on building level, is a challenging task. Machine Learning algorithms like Random Forest have proven useful in pred...

Landscapes and human settlements evolve over long periods of time. Land change, as one of the drivers of the ecological crisis in the Anthropocene, therefore, needs to be studied with a long-term perspective. Over the past decades, a substantial body of research has accumulated in the field of land change science. The quantitative geospatial analys...

While neoliberalisation has long drawn scholarly attention, there have been few attempts to quantify the course of restructuring under neoliberal urbanisation. This paper aims to describe and quantify the restructuring process in India for the period 1991-2011. Theoretically embedded in the notion of "creative destruction", the paper adopts a multi...

Urban green spaces (UGSs) can provide important ecosystem services for citizens and their well-being. To make use of these services according to UGS user demands, urban residents, tourists, and city administrations should know where UGSs are located, what qualities they have and how to reach them on convenient routes. This paper presents a novel di...

Public urban green spaces are important for the urban quality of life. Still, comprehensive open data sets on urban green spaces are not available for most cities. As open and globally available data sets, the potential of Sentinel-2 satellite imagery and OpenStreetMap (OSM) data for urban green space mapping is high but limited due to their respec...

Full-text available
Literature on urban ecosystem services (UESS) is vast, particularly on cultural ecosystem services. However, due to a lack of knowledge on individual urban green spaces on the site level, further research on enhanced methods is needed to underpin existing assumptions about the reasons why people are visiting urban green spaces and what kinds of eco...
