The world is being swept by the wave of smart cities, and Geographic Information System (GIS) technology plays a key role in it. This article explores the application status and development trend of GIS technology in urban planning from the perspective of smart cities. By sorting out the application value of GIS in urban strategic layout, multi system collaboration, and precise services, it explains the necessity of promoting the transformation of planning towards intelligence. We have summarized and organized the practical points of GIS in areas such as overall planning, underground space, landscape, and transportation, including spatial simulation, 3D management, ecological integration, and dynamic optimization. Looking ahead to the future, the cross integration of GIS with artificial intelligence, 3D modeling, carbon neutrality monitoring, data collaboration, and other technologies will drive planning towards a new stage of development that is more intelligent, refined, open, and green. With the empowerment of GIS, we aim to create sustainable cities that are resilient, low-carbon, and inclusive, making urban life better.
