The utilization of three-dimensional (3D) technology has led to significant progress in the analysis and comprehension of geographical data within geographic information systems (GIS). This study used the Al-Jadriya area in Baghdad, Iraq, as an example of how 3D GIS may be used to analyze and manage urban environments. By integrating 3D models of buildings, landscape, and infrastructure, urban planners and decision-makers can obtain vital insights into the potential implications of proposed developments, simulate traffic patterns, and discover hiding threats. We can strengthen disaster management and emergency response skills by giving complete insights into the built environment and possible risks. This research aims to investigate the benefits of 3D GIS while emphasizing the need of enhancing urban planning and management approaches. Stakeholders may improve urban development plans, increase the safety and efficacy of Zeyart AL-Arbaeen, and much more by using the potential of 3D GIS technology. Population control, population movement management, and the security of millions of people attending this massive event are all advantages of 3D GIS.
