UTILISATION OF CITYGML MODULES TOWARD THE DEVELOPMENT OF THREE-DIMENSIONAL (3D) CITY MODEL FOR CITY PLANNING

Abstract

Recent developments in the massive 3D acquisition area made possible the generation of dense and precise 3D data, ranging from the representation of a simple building to a whole city. Nowadays, increasing urbanization, rapid growth of urban areas, and subsequently development of mega cities, are among the most important changes occurring worldwide. Therefore, developing techniques to manage these cities seems quite necessary. The aim of this paper is to explore the utilisation of few selected CityGML modules toward the development of 3D City Model for possible 3D City Planning. The paper focuses on addressing the challenging issues that derive from a complex virtual 3D citymodeling. More specifically, the paper investigates a complex built-up area, presenting and analyzing its constituting structures. Within this framework, the following CityGML modules are investigated: Bridge, Transportation Complex, CityFurniture, Land Use and Vegetation. To this purpose, the Building Information Modelling (BIM-Standard software SketchUp and the data conversion tool Feature Manipulation Engine (FME) are used. The processes of both modeling and converting are analyzed in detail. General conclusions and future research considerations are presented.
