In an era where urban landscapes are rapidly evolving, the integration of Geographic Information Systems (GIS) in urban planning emerges as a pivotal tool for sustainable development. This paper delves into the multifaceted role of GIS, exploring its implications in the realms of business and environmental sustainability within urban contexts. The background of the study is rooted in the increasing complexity of urban challenges and the need for innovative solutions to address them effectively. The aim of this paper is to provide a comprehensive analysis of GIS applications in urban planning, focusing on their impact on both business efficiency and environmental stewardship. The scope of the study encompasses an exploration of the historical evolution of GIS, its integration in various urban settings, and the interplay between commercial objectives and environmental sustainability. Employing a methodological framework that includes a thorough review of relevant literature and case studies, the study illuminates the dynamic interplay between technological advancements in GIS and their practical applications in urban planning. This approach facilitates a panoramic view of GIS's multifarious implications, highlighting trends, patterns, and impacts of its adoption in diverse urban scenarios. The main conclusions reveal that GIS is indispensable in modern urban development, adeptly addressing complex urban challenges, particularly in sustainable planning and balancing economic growth with environmental protection. However, the study also uncovers challenges such as the need for improved database construction and comprehensive information services. Recommendations include tailoring policies to local contexts, focusing on multi-scalar GIS-based indicators, and prioritizing sustainable development goals. These strategies are crucial for enhancing the efficacy of GIS in urban planning, leading to more sustainable and well-managed urban environments.
