Geographical Information System (GIS)

A Geographic Information System (GIS) is a computer-based tool that captures, stores, analyzes, and displays spatial data—information about locations and shapes on Earth's surface. It helps users understand patterns, relationships, and trends by layering different types of geographic information, such as maps, satellite images, and demographic data. GIS is used in various fields—from urban planning and environmental management to emergency response—allowing decision-makers to visualize complex data geographically, make informed choices, and solve problems related to location and spatial relationships effectively.
