Abstract
Skyline can be an effective component in explaining the spatial and qualitative features of the urban landscape. Ignoring this important category, as well as not observing the proportion between the height of the wall and the width of the street, leads to the creation of an abnormal appearance and in some cases, excessive confinement in city streets. It is obvious that the streets do not only have a physical dimension, but also represent life and dynamics in communities and cities. Therefore, skyline can be an effective component in improving the quality of the urban landscape.
In this research, the library studies methods and field surveying have been used. ArcScene was used for height simulation and evaluation of the appropriate as well as the required analysis (skyline, skyline graph, etc.). The selected areas in the city were from the new fabric (less than 20 years old), middle fabric (about 50 years old) and old fabric (more than 50 years old). The results obtained from the skyline graph analysis show that the skyline pattern of South Shariati Street (old fabric) with an average of 74.06% has better view of the horizon than Imam Khomeini street with an average of 63.5% and Takhti street with an average of 55.66%. Also, this research explains the reason for the relatively irregular skyline caused by high density sale in Tabriz metropolis, the method of densification and height zoning of that area. The results of 3D analysis show the existence of a direct relationship between the heights of building. In this way, the more proportional the height of the buildings, the more open the space will be, and the wider the passage, the wider the radius of the skyline graph will be.
