Sky View Factor layer of Florence (Tuscany, Italy)

Sky View Factor (SVF) is a dimensionless parameter that returns, with values between 0 and 1, the degree of exposure of a surface to the celestial vault, or the portion of the sky visible from a certain point located at ground level (Oke, 1981). This factor is influenced by urban elements geometry: values close to 1 correspond to a large visible portion, while values close to 0 indicate a limited vision of the sky.

The Florence SVF layer is a raster data (Reference System RDN2008 / UTM zone 32N - EPSG: 7791; extent: 673142.13 – 4843854.78; columns number / rows number: 15000 / 12154) with 1 m spatial resolution: it was calculated by the Digital Surface Model (DSM), obtained from the 2017 Lidar dataset. Lidar-DSM layers are available on the OpenData platform of Florence Municipality at the following link: http://dati.toscana.it/dataset/dsm-2017 (accessed on 29/01/2021).
