GIS, or Geographic Information System, is a technology used to collect, store, analyze, and display geographic data. It allows users to create maps and visualizations that show information about locations, such as roads, land use, population, or natural resources. GIS combines data from various sources, like satellite images and surveys, to help with decision-making in areas like urban planning, environmental protection, and transportation. It is a valuable tool for studying patterns and relationships between different features on the Earth's surface.
