Geographic Information Systems (GIS) and Remote Sensing (RS) play integral roles in modern urban planning by providing comprehensive spatial data and analytical tools. This study examined the application of GIS and RS in urban planning, focusing on their capabilities in data acquisition, analysis, visualization, and decision-making. The integration of GIS and RS technology enables planners to assess urban environments, monitor changes, and formulate sustainable development strategies. Case studies have highlighted the effectiveness of GIS and RS in addressing various urban planning challenges, such as land use management, infrastructure planning, environmental conservation, and disaster mitigation. Additionally, this study discusses emerging trends and future directions for utilizing GIS and RS to enhance urban planning processes and outcomes.
