Automated generation of versatile data model for analyzing urban architectural void

Urban environments are defined and modeled in a variety of ways depending on the scientific approach to analyze them. Even though a number of analysis could benefit from using a single model and re-using results of one for the sake of the other, so far no single data model is available. Moreover, the existing standardized models focus on describing objects in and around urban architectural void rather than the spaces themselves. Nevertheless, a number of phenomena such as heat, energy, pollution, also including social and mobility aspects would undoubtedly benefit from using a model that is explicitly focused on defining the urban architectural void and its characteristics as continuous field, interconnected network or series of spatial units. Therefore, this paper aims to suggest a versatile data model that would allow to separate, interpret, analyze and visualize the urban architectural void using a standardized automated procedure. The model relies on Gestalt theories for space compartmentalization. It allows performing various kinds of analysis and storing their results in a unified format using core concepts of GIS. The model can be rendered both as a 2D and 3D representation. Finally, user intervention and parameter calibration is allowed at every principal step of an automated procedure. •The paper suggests a versatile data model that is focused on modelling the urban architectural void instead of the solid objects in the urban environment.•The suggested data model has features needed to represent and analyse urban space as a continuous field, network or series of separate spatial units.•An automated procedure is suggested to construct the versatile data model based on topographical data and 3-dimensional data on urban limits.
