Classifying a city according to the local climate zone (LCZ) scheme can provide insights into the thermal issue of urban planning. The different zones of the LCZ scheme feature particular morphological properties in terms of terrain roughness class, aspect ratio, sky view factor, surface admittance, etc. Our goal is to define the values for remote sensing and/or GIS based properties that can be used to extract local climate zones in Brussels, Belgium. The results showed similar values for LCZ

... LCZ 3, LCZ 6, LCZ 8, LCZ 9, LCZ A, LCZ B and LCZ D compared to the zone property threshold set in the LCZ datasheets. We were not able to delineated characteristic values for aspect ratio, terrain roughness, surface admittance, albedo and Anthropogenic heat flux. Overall we can conclude that this preliminary study shows good results for the city of Brussels. More research should be done to confirm these results and to explore the OBIA approach based on these results.
