GIS (Geographic Information System)

A Geographic Information System (GIS) is a technology used to collect, analyze, and visualize geographic data. It helps users understand spatial relationships and patterns by displaying information on maps. GIS combines data from various sources—like satellite imagery, survey data, and databases—to help in decision-making across fields such as urban planning, environmental management, and public health. For example, it can identify areas at risk of flooding or help locate suitable sites for new parks. Essentially, GIS transforms complex geographic data into accessible, actionable insights for better planning and resource management.
