“…From an academic perspective, the continuous advance of spatial modelling in the field of visual landscape assessment is a prospective research area, knowing that the complexity of the methods used, the amount of data analysed, and the computation power required cannot be provided in standard planning applications by the practitioners themselves. Thus, this paper shall also contribute to raising the awareness about what is technically possible, which is an underutilized potential [66].

Large area visual landscape quality assessment, especially at the national level is needed to answer the demand from strategic planning. In our paper, we describe and compare two recent modelling approaches for this task regarding their theoretical and empirical basis, resolution, model configuration and results. To compare the outcomes of the two methods, both correlation measures and a visual overlay analysing the inversions are used. The results show, that despite the different methodological approaches, in over 90% of the area of Germany there are only minor deviations between the resulting scenic quality maps (less or equal one step on a five-step scale). The main differences occur due to a different relative weight given to terrain and water indicators in the respective methods. We conclude that a methodologically valid scenic quality evaluation using geodata of homogenous quality is possible also at the national level. By triangulating between different methods, for both, the validity could be proven. The datasets elaborated can also be used as a benchmark for regional landscape assessments and for an upcoming monitoring of changes in visual landscape quality.

“…An isovist represents all the visible points from the desired point in space, which can be used to study the behavior and perception of space users (Benedikt, 1979;Davis and Benedikt, 1979). Thus, several quantitative descriptors such as physical properties of space, i.e., area, number of vertices, length of the perimeter and length of closed and open intervals& Wiener, 2008), and information about what users see (geographical area View) or, how their angle of view (Liu and Nijhuis, 2020) is obtained by analyzing the observation graph.…”

Regarding the significant impact of visibility, landscape, and thermal comfort on the presence of users’ attendance in urban parks, there is a severe interest in studies on the amount of visibility and the outdoor thermal comfort especially in a district with hot summers. this research, after investigating the shafagh park based on space laws and the relationship between park spaces with each other in terms of accessibility and visibility to achieve the effect of plants, then, based on the obtained data, the role of plants in evaluating thermal comfort conditions in the park space was investigated and finally, their relationship with each other has been examined. results have revealed that, plants have an undeniable role in improving the conditions of thermal comfort and visual visibility and user movement in spaces, so that, the best points in terms of thermal comfort, had a favorable view and perspective, while, areas of the park that did not have good visibility and landscape did not experience favorable conditions in terms of thermal comfort. Therefore, architects, landscape architects, and urban designers who research the problem of thermal comfort and landscape analysis in urban parks can use the findings of this article for effective outcomes, especially in parks with climatic conditions use similar in Tehran.

“…For example, the best detail recognition occurs in the central view zone (around 13 degrees), whereas detail recognition declines in the peripheral view zone at 107 degrees [75]. Furthermore, the visibility of space is influenced by the movement speed of a pedestrian as well as interactions with other pedestrians and behavior associated with wayfinding [76]. Lighting and weather also impose various influences on visibility.…”

Chaos in Motion: Measuring Visual Pollution with Tangential View Landscape Metrics

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.
