Description
Mapping of the urban areas of Athens, Larissa and Rethymno into Local Climate Zones (LCZ). Data are available as raster images at a 100 m resolution.
The LCZ classification system (Stewart & Oke, 2012) divides cities into discrete zones with specific urban form and function characteristics. Using remote sensing data, digital elevation models from the Hellenic Cadastre, and GIS data, we first derived urban morphological parameters, including the building height, the vegetation plan area fraction and the canyon aspect ratio. Then, each pixel was assigned using a decision tree to an LCZ, according to the range of possible values that an urban parameter can exhibit per zone.
