Representation of historical buildings in 3D gis environment for smart city studies: Ankara, Hamamönü case

The recent developments in information technologies has led to the preservation of historical monuments and transferring them to future generations one of the important tasks for humanity. Advances in 3D modelling methods has also expanded parallel with the technological developments. 3D city modeling and smart city studies dramatically increased and attract the attention of researchers. Modeling studies in this area are widely used in urban planning, historical building modeling and similar applications. 3D modeling is becoming more important each year, and researchers still working on modeling cities in higher level of detail. Upgrading and defining buildings details is a necessary work in 3D modeling studies. There are various processing methods for defining these details and attributes to perform 3D queries. User-oriented 3D queries and analysis processes on web is becoming popular and gaining importance. One of the important tourism center of Turkey is Tacettin Sultan Mosque in Ankara. Tacettin Mosque and its surrounding area has been choosen as study area of this thesis. Attribute information added to the mosque and surrounding buildings, then published on web with different query options. A couple of different software solutions such as NetCAD, AutoCAD, 3Ds Max, ArcGIS and Esri CityEngine has been used in this study. Generated model stored as geodatabase that allows queries on model. The final output of 3D city model is published on web with ArcGIS online. As the result of study, attribute and location information of 2D data can be transferred to generated 3D building models. The applications of 3D city models can be used for different research purposes from various disciplines, and the produced informations can be applied to different research areas.
