Sky view factor estimation from street view images based on semantic segmentation

Urban Climate, 2021
Abstract The sky view factor (SVF) has been recognized as an indicator to evaluate the openness of streets in the field of urban planning. It represents the ratio of the visible sky area to the total sky area at one point in space. However, due to the time-consuming and laborious acquisition of data and manual detection in traditional measurement ...

Graphical estimation of sky view-factors in urban environments

Journal of Climatology, 1987
AbstractA technique is described whereby sky view‐factors in urban locations can be estimated from graphs once azimuth and elevation angles of surrounding buildings are known. The graphs are easy to use and give results sufficiently accurate to enable their use when more elaborate computing or photographic equipment is unavailable.
