A Geographic Information System (GIS) is a powerful tool used for capturing, storing, analyzing, and managing spatial and geographic data. It allows users to visualize data in the form of maps, making it easier to understand patterns, relationships, and trends in various fields such as urban planning, environmental science, and transportation. GIS integrates various data sources, including satellite imagery, GPS data, and demographic information, to provide insights that support decision-making. By combining layers of information, GIS helps in solving complex problems and enhances our ability to plan and manage resources effectively.
