Analysis of the Influence of Sky View Factor on Urban Surface Temperature Based on Multi-Source Data

2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021
Sky View Factor (SVF) is an index describing the geometry of urban buildings, reflecting the visibility range of urban buildings and affecting the urban surface energy balance and urban thermal environment.

Positional error modeling of sky‐view factor measurements within urban street canyons

Trans. GIS, 2021
The sky‐view factor (SVF) in the urban street canyon is a single point‐specific measurement that can only represent the ratio of the visible sky of a specific point.

Sky View Factor Calculation Method Based on Fisheye Image Correction

Geomatics Science and Technology
Sky View Factor (SVF) is one of the essential indicators for urban thermal environmental assessment. The method of estimating SVF using fisheye photographs is fast and accurate, but it is restricted by equidistant projections.

Analysis of the Influence of Sky View Factor on the Thermal Environment of Coastal Settlements in Gorontalo City based on IoT Measurements

International Journal of Civil Engineering
Tropical coastal urban areas are highly vulnerable to climate-induced stress, and thus, a process-based understanding of how the urban morphology regulates microclimate and thermal comfort is required. This paper assesses the impact of SVF on the thermal
