Abstract
The preliminary phase in any architectural heritage project is to obtain metric measurements and documentation of the building and its individual elements. On the other hand, conventional measurement techniques require tremendous resources and lengthy project completion times for architectural surveys and 3D model production. Over the past two decades, the widespread use of laser scanning and digital photogrammetry have significantly altered the heritage documentation process. Furthermore, advances in these technologies have enabled robust data collection and reduced user workload for generating various levels of products, from single buildings to expansive cityscapes. More recently, the use of procedural modelling methods and BIM relevant applications for historic building documentation purposes has become an active area of research, however fully automated systems in cultural heritage documentation still remains open. In this paper, we present a semi-automated methodology, for 3D façade modelling of cultural heritage assets based on parametric and procedural modelling techniques and using airborne and terrestrial laser scanning data. We present the contribution of our methodology, which we implemented in an open source software environment using the example project of a 16th century early classical era Ottoman structure, Sinan the Architect’s Şehzade Mosque in Istanbul, Turkey.

Summary
Cultural heritage structures play an important role in sustaining the relationship between man and his past. In order to preserve cultural heritage assets for the generations, fast and accurate documentation of structures and their surrounding areas based on scientific techniques need to be developed. Laser scanning technology has become widely used over the last decade for conservation and documentation projects. Systems that integrate point cloud processing methodologies with Building Information Modeling (BIM) applications for efficient final products for preserving and managing cultural heritage structures are gaining importance. In this paper we present a methodology for decreasing the user input in the geometry generation of architectural elements with a special emphasis to classical era Ottoman mosque design elements
