Visibility maps of Turin

The article presents a simple but accurate method for generating visibility maps based on the above criteria and demonstrate its effectiveness for a newly erected skyscraper in Turin, Italy. Visibility can be indicated from parameters that describe the atmospheric conditions, but it is more feasible to use sight distances registered over time by weather stations. The sight distances should preferably be collected hourly, and such high-frequency observations can be obtained from international databases. If one of the four corner points is visible, then the building is indicated as visible. Using geometric computations and visual acuity, the length of the line of sight appeared to be 218km. Subsequently, visibility constraints were introduced based on atmospheric conditions. The method allows it to be determined at design stage how the (psychological) perception of places in an urban landscape will change when new buildings are erected or existing buildings are demolished. This provides valuable information for architects and city planners.
