Spatial information systems

Spatial information systems, often referred to as geographic information systems (GIS), are tools that capture, store, analyze, and visualize data related to locations on Earth. They combine maps with data, allowing users to see patterns, relationships, and trends based on geography. For example, GIS can help urban planners design better cities by showing where buildings, parks, and roads should go. Essentially, these systems help us understand the "where" behind various information, enabling informed decision-making in areas like environmental management, transportation, and public health.
