Abstract

Assessment of green visibility exposure is challenging foralarge spatial extentand inacomplex built environment. In this study,we demonstrated an innovative application of viewshed-based greenness visibility index (GVI) modelling at a fine spatial resolution for each location within the study area. We validated our GVI against acommonly used index based on randomly sampled locations with available Google Street View (GSV) images. We observed very strong positive, significant correlations between our GVI values GSV-based index (r = 0.943, p = 0.001).Our method allows accurate, efficient and comprehensive greenness visibility assessment, not just along roads.
