Owing to the increasing need to catalogue and protect important urban heritage around the world, several recording techniques
including Photogrammetry and 3D Scanning are used to create accurate digital models of historic sites or objects. However, the
accuracy of the product varies with the technology used and the budget available for the purpose since sophisticated equipments are
still expensive. This project firstly involved the examination of various kinds of built architecture such as wind towers and public
buildings in order to examine their role in creating a historical reference for the built environment of the United Arab Emirates.
Then, an important historical site was selected for further analysis, with the aim to eventually recreate it digitally using existing data.
In order to do this, a photographic survey of the site was produce, and a 3D model was generated using existing cartography
combined with the results of on-site surveys. In addition, the paper discusses the use of 3D digitisation and the digital modelling
process, and assesses the benefits and limitations of this technology particularly with respect to urban 3D modelling. A preliminary

research into scanning and digitisation methods including Photogrammetry was carried out to assess their applicability to the project.
The implementation of the project resorted to the use of low-cost recording techniques owing to the limited resources available to
the study. The project revealed that several recording techniques and software are needed in order to achieve optimum results.
Further analysis is required to assess the applicability of the method used and the usefulness and applications of the produced model.

The aim here was to create a 3D model to which a number of attributes can be added in addition to visualisation and 3D animation to
achieve effective examination and production of improvement or renovation proposals.
