Visual pollution (VP) in the form of outdoor advertisements (OA) is a threat to landscape physiognomy. Despite their proven usefulness in landscape aesthetic studies, landscape metrics have not yet been applied to address the phenomenon of VP. To fill this knowledge gap, a methodological framework for the measurement of VP using tangential view landscape metrics is proposed, which is accompanied by statistically significant proofs. Raster products derived from aerial laser scanning data were used to characterize two study areas with different topographic conditions in the city of Lublin, East Poland. The visibility of the cityscape in motion was simulated through viewshed measurements taken at equal intervals in the forwards and backwards directions along pedestrian walkways. The scrutinized tangential view landscape metrics (visible area, maximum visible distance, skyline, Shannon depth, view depth line) was the object of a two-fold interpretation wherein the spatial occurrence of VP as well as its impacts on the visual landscape character (VLC) were examined. The visible area metrics were found to be highly sensitive VP indicators. The maximum visible distance metrics provided evidence for the destructive effect of OA on view corridors. The Shannon depth and depth line metrics were not found to be statistically significant indicators of VP. Results from directional viewshed modelling indicate that distortion in the analyzed cityscape physiognomy depends on the view direction. The findings allow for particular recommendations with practical implementations in land use planning, which are discussed along with limitations to our proposed methods.
Subvertising, a portmanteau for ‘subverting advertising’, is the illicit practice of intervening into urban advertising space, from graffiti scribbles and removed adverts, to full-blown billboard t...
This paper focuses on the combined impact of sound and visibility features on residential satisfaction in a suburban context. Based on a modeling approach, the study presents an integrated analysis where a set of spatial metrics, describing visibility of landscape features and road-traffic noise, are associated with data from a survey of neighborhood satisfaction. This survey was conducted on a sample of 845 inhabitants living in a medium-size French city. Using a PLS path model, the main object...
The measurement of night sky quality has become an important task in nature conservation. The primary device used for this task can be a calibrated digital camera. In addition, colour information can be derived from sky photography. In this paper, we provide a test on a concept to gather information about the possible sources of night sky brightness based on digital camera images. This method helps to understand changes in night sky quality due to natural and artificial changes in the environmen...
The article is dedicated to the phenomenon of spatial chaos in the suburban areas of Polish cities, which, due to uncontrolled scattering of buildings (urban sprawl), require urgent retrofitting. These activities should contribute to the gradual densification of buildings and the more frequent functioning of suburbanites in the local environment, close to the place of residence. The authors claim that the retrofitting of suburbs can be accomplished by impacting two dimensions of spatial chaos: l...

The location of highway signs has a significant impact on timely route-finding and also on avoiding potential driver confusion. This paper proposes an approach based on three-dimensional spatial an...
This paper introduces a design-focused typology of psychological human needs that includes 13 fundamental needs and 52 sub-needs (four for each fundamental need). The typology was developed to provide a practical understanding of psychological needs as a resource for user-centered design practice and research with a focus on user experience and well-being. The first part of the manuscript briefly reviews Abraham Maslow’s pioneering work on human needs, and the underlying propositions, main contr...
This paper is based on the results of an extensive (840-page) report of the Committee on National Spatial Development of the Polish Academy of Sciences, entitled Studies on Spatial Chaos (edited by A. Kowalewski, T, Markowski and P. Śleszynski—Studia KPZK PAN, vol. 182, Warsaw 2018—in Polish). Its aim was to conduct a comprehensive and detailed study on the problem of spatial chaos (spatial disorder), including an estimate of economic costs in Poland. For this purpose, literature was queried (ar...
Social media continues to grow, permanently capturing our digital footprint in the form of texts, photographs, and videos, thereby reflecting our daily lives. Therefore, recent studies are increasingly recognising passively crowdsourced geotagged photographs retrieved from location-based social media as suitable data for quantitative mapping and assessment of cultural ecosystem service (CES) flow. In this study, we attempt to improve CES mapping from geotagged photographs by combining natural la...

Abstract Mapping landscape spaces by means of manual and modern technology enables landscape architects to describe, understand, and interpret spatial-visual properties of landscape. This can help to strengthen the body of knowledge of spatial design in landscape architecture through measurement and visualization of common concepts in the field, as well as through the possibility to explore spatial-visual landscape features that was not possible before. Despite the wide ranging possibilities and...
Krakow is a city of high landscape values, which has found confirmation in the entry onto the UNESCO heritage list. Its cultural landscape requires protection and clarification within the context of intensive tourist use and a rapid pace of urban spatial development. For preservation protection and restoration of landscape values, the city authorities undertook work on the creation of a Cultural Park in the Stradom and Kazimierz districts, providing a comprehensive, sustainable, and multidiscipl...
The paper presents the development of conceptual, theoretical, and methodological foundations of a complex and novel method for evaluating visual–aesthetic values of landscape. The novelty lies in the combination of methods for assessing the overall attractiveness of the landscape (geocomplex) and the view field (as seen from an observation point). The analysis was carried out for a highly environmentally diverse fragment of the Malopolska Upland (central Poland). The proposed method of evaluati...
Urban visual pollution is increasingly affecting the built-up areas of the rapidly urbanizing planet. Outdoor advertisements are the key visual pollution objects affecting the visual pollution index and revenue generation potential of a place. Current practices of uninformed and uncontrolled outdoor advertising (especially billboards) impairs effective control of visual pollution in developing countries. Improving this can result in over 20% reduction of visual pollution. This article presents a...
