DIGITIZING URBAN CODES TO SUSTAIN URBAN CHARACTER OF HISTORIC DISTRICTS: A CASE STUDY OF ROSETTA CITY, EGYPT

Introduction: Effective urban planning relies on comprehensive knowledge of both physical and non-physical urban elements, which is vital for developing GIS models that support sustainable urban development by providing realistic representations of urban contexts. Accurate 3D models are critical for analyzing urban systems and processes. Aim: This study aimed to evaluate the impact of 3D GIS urban digitizing techniques and visualization methods on the feasibility of urban codes in preserving urban identity and character, with a focus on Rosetta City, Egypt. Methods: The research employed descriptive, analytical, and empirical approaches. Field visits, surveys, GIS simulations, and digital tools like ESRI CityEngine were used to create 3D GIS models. These models help digitize and analyze urban code parameters by using the form-based code approach. Results: The study demonstrates that 3D GIS models can enhance urban planning by improving the understanding of urban codes and their implications for preserving urban identity. The models provide insights into maintaining historical character while supporting development. Discussion: The findings highlight the potential of 3D urban models to improve decision-making in urban planning and underscore the value of such models in preserving the unique identity of historic districts like Rosetta City, offering a framework for similar regions.
