CityGML model generation using parametric interpolations Available to Purchase

With an upsurge in energy demand throughout the globe, efficient energy simulations and smart energy-management solutions are imperative. Often a lack of substantial three-dimensional geometrical data restricts simulation scientists and urban planners to analyse energy demand patterns on a city scale. Therefore, in this paper, the authors describe the open-source City Geographical Markup Language (CityGML) Building Interpolation Tool (CityBIT) for the creation of user-defined and interpolated CityGML LoD2 building models for planned and/or existing buildings. CityBIT can be used to generate CityGML models with different roof types, orientations and elevations. A brief explanation of the functionalities of the tool and the methodologies adapted to develop the tool is provided in this paper. CityBIT aims to facilitate CityGML geometric model development focusing on urban energy performance simulations.
