GIS (Geographical Information Systems)

Geographical Information Systems (GIS) are computer-based tools used to collect, analyze, and visualize spatial data—information tied to specific locations on Earth. They combine maps, satellite images, and various data layers (like roads, terrain, or demographics) to help us understand patterns and relationships in the environment. GIS is used in urban planning, disaster response, resource management, and many other fields to make informed decisions by visualizing complex data geographically, improving insight and efficiency in tackling real-world problems.
