Abstract
Studying the altered urban environment is important because of the high number of the involved inhabitants. In urban areas surface cover and geometry differ from the rural surfaces, and the water and energy balances are modified. As a result the thermal environment and the airflow conditions are modified, and these modifications affect the energy consumption and wind energy potential in urban areas. The evaluation of the urban surface geometry and its parameters are not straightforward, and still a rapidly developing field of research. In this paper new software methods for the calculations of urban surface parameters are presented. These software tools enable us to evaluate the building and tree-crown databases from spectral and elevation data, and to use these two datasets to calculate SVF and roughness parameters. These software tools were applied for the study area in Debrecen, Hungary, in order to test the methods and to gather information about the variance of the urban surface in this city. Using the results the heating/cooling energy demand of the households and the wind energy potential can be estimated in urban areas.
