This paper outlines a two stage approach for digitally recording cultural heritage sites. This approach involves a 3D modeling stage and the integration of the 3D model into a 3D GIS for further management and analysis. The modeling stage is carried out using a new concept; Historic Building Information Modeling (HBIM) which has been developed at the Dublin Institute of Technology [12]. Historic Building Information Modeling is a system for modeling historic structures from laser scan and photogrammetric data using Building Information Modeling (BIM) software. The HBIM process involves a reverse engineering solution whereby parametric objects representing architectural elements are mapped onto laser scan or photogrammetric survey data. A library of parametric architectural objects has been designed from historic manuscripts and architectural pattern books. These parametric objects were built using an embedded scripting language within the BIM software called Geometric Descriptive Language (GDL). These objects are combined and mapped onto the survey data to build the entire model. After the 3D model has been created the next stage involves integrating the 3D model into a 3D GIS for further analysis. The international framework for 3D city modeling, CityGML has been adopted for this purpose. CityGML provides an interoperable framework for modeling 3D geometries, semantics, topology and appearance properties [13]. The aim of this research is to bridge the gap between parametric CAD modeling and 3D GIS while using benefits from both systems to help document and analyze cultural heritage sites.
