GIS technologies assist in urban planning by providing comprehensive data analysis and visualization tools. These technologies enable planners to assess environmental impacts, land use, and population density. By mapping infrastructure, transportation routes, and community facilities, GIS helps identify areas for development or conservation. Furthermore, planners can simulate scenarios for potential projects, helping stakeholders understand implications before implementation. The integration of GIS fosters informed decision-making, enhances efficiency, and encourages community engagement, ultimately leading to smarter and more sustainable urban development.
