“…However, our aim was to check how the viewshed from individual viewpoints has changed from the position of an observer-tourist. This is important for this area because it is attractive for tourists and covered with a relatively dense network of walking trails [87].…”

A viewshed analysis is of great importance in mountainous areas characterized by high landscape values. The aim of this research was to determine the impact of reforestation occurring on former pasturelands on changes in the viewshed, and to quantify changes in the surface of glades. We combine a horizontal and a vertical approach to landscape analysis. The changes in non-forest areas and the viewshed from viewpoints located in glades were calculated using historical cartographic materials and a more recent Digital Elevation Model and Digital Surface Model. An analysis was conducted using a Visibility tool in ArcGIS. The non-forest areas decreased in the period 1848–2015. The viewshed in the majority of viewpoints also decreased in the period 1848–2015. In the majority of cases, the maximal viewsheds were calculated in 1879/1885 and 1933 (43.8% of the analyzed cases), whereas the minimal ones were calculated in 2015 (almost 57.5% of analyzed cases). Changes in the viewshed range from 0.2 to 23.5 km2 with half the cases analyzed being no more than 1.4 km2. The results indicate that forest succession on abandoned glades does not always cause a decline in the viewshed. Deforestation in neighboring areas may be another factor that has an influence on the decline.

Given the current demands for biodiversity conservation and climate mitigation, understanding the dynamics of fragmented forests in one of the most threatened regions of the Atlantic Forest is essential for supporting small and large-scale forest restoration initiatives. We investigated the patterns of forest loss, recovery, and stability from 1985 to 2020. We classified and quantified forest cover using temporal and spatial descriptors and related them to their causal agents. We hypothesised that there is a spontaneous natural regeneration process in abandoned areas, protected areas, and near the hydrographic network, but anthropogenic land uses negatively affect this process. Consequently, we observed that despite an increase in forest cover over the years, there was a loss of medium and large fragments of old-growth forests due to agriculture and urban infrastructure expansion, especially in flat areas and near watercourses. The increase was mostly comprised of small young forests in abandoned and protected areas, especially near watercourses. Forest stability was explained by proximity to municipality administrative units. This research elucidates the dynamics of forest patches in a severely threatened Atlantic Forest region. It revealed the replacement of large and medium mature forest fragments with small fragments of young forest. Thus, our results reinforce the need for monitoring forest stability, avoiding forest loss, and incentivising forest gain for biodiversity and ecosystem service conservation.

What can we see from the road? Applications of a cumulative viewshed analysis on a US state highway network

Abstract. In many parts of the world, motorized travel is one of the most common ways that people interact with their regional landscape. This study investigates how travelers' understandings of place might be influenced by what landforms they can see from a vehicle. It uses a cumulative viewshed analysis on the Washington State (United States) highway network to determine which physical landscape features are most frequently visible or obscured from the road. Adapting ideas from Kevin Lynch's The Image of the City, I propose spatial data processing methods to derive landmarks, edges, and districts that could most contribute to the mental maps of travelers and should be prioritized for labeling on print, electronic, and augmented reality maps. Other applications of the cumulative viewshed include deriving scenic byways, siting proposed construction for high or low visibility, and guiding conversations about critical toponymy and perceptions of place.
