local.description.resumoThe urban form representation to apply in studies of urban climate is a challenge especially in cities of developing countries. These cities lack planning, thus the urban fabric is heterogeneous and several types of buildings are mixed in the same area. Considering this reality, the paper will compare three methods to calculate urban surface parameters. These parameters were compared with the WUDAPT classification. The software QGIS was used to develop models to calculate the following urban surface parameters: plan area ratio (λp), complete building aspect ratio (λbc), and mean height of buildings (hm). Three grid size were applied for calculations: 100 m, 500 m, and 1 km. λbc was the only geometric property able to express the difference of density and the absolute size of the active surface of buildings as a unique parameter. The methods developed have some advantages: (a) they are based on realistic shapes of buildings, (b) they were developed in a free and open source system, (c) and it is possible to vary the calculation grid size.
