Geographical Information Systems (GIS) are powerful tools used to capture, store, analyze, and manage spatial and geographic data. They enable users to visualize data in the form of maps, making it easier to understand patterns and relationships in various fields such as urban planning, environmental science, and transportation. By integrating various data sources, GIS helps in decision-making processes by providing insights into geographical trends and issues. This technology is widely used by governments, businesses, and researchers to improve resource management and enhance public services, ultimately leading to more informed and effective strategies.
