Popis / Abstract:

The aim of the article is to assess the visibility of the planned high-rise buildings – Prague Eye Towers in Prague. Commonly used methods either do not provide sufficient information about visibility (viewshed analysis) or the results cannot be spatially evaluated (photomontages and 3D visualizations). However, extended viewsheds and reverse viewsheds can provide appropriate results that can be spatially evaluated to assess the visibility of planned buildings from important lookout places, including the neighbourhood of the building. The study utilised open data provided by © IPR Praha – digital surface model, digital terrain model, relative heights of buildings and the current status of land use. Based on these datasets, two extended viewsheds of planned buildings are determined to analyse the significance of a building over the local horizon including the visible part of the building. The obtained results are used for assessment of visibility of planned buildings and can be also utilised in further urban planning applications. The article shows how the visibility of buildings can be assessed and their impact on a city evaluated.
