Kunihiko Fujiwara, Ryuta Tsurumi, Tomoki Kiyono +6
Three-dimensional urban environment simulation is a powerful tool for informed urban planning. However, the intensive manual effort required to prepare input 3D city models has hin…
ZenSVI: An Open-Source Software for the Integrated Acquisition, Processing and Analysis of Street View Imagery Towards Scalable Urban Science
Koichi Ito, Yihan Zhu, Mahmoud Abdelrahman +9
Street view imagery (SVI) has been instrumental in many studies in the past decade to understand and characterize street features and the built environment. Researchers across a va…
Coverage and Bias of Street View Imagery in Mapping the Urban Environment
Zicheng Fan, Chen-Chieh Feng, Filip Biljecki
Street View Imagery (SVI) has emerged as a valuable data form in urban studies, enabling new ways to map and sense urban environments. However, fundamental concerns regarding the r…
