GIS, or Geographic Information Systems, plays a crucial role in urban planning by enabling planners to visualize, analyze, and manipulate spatial data. It helps in identifying patterns, assessing land use, and planning infrastructure projects, thereby informing policy decisions and resource allocation. GIS also enhances public participation by allowing stakeholders to visualize plans and scenarios effectively. By integrating multiple data layers—such as demographics, environmental factors, and transportation networks—GIS supports more sustainable and informed urban development.
