Geoinformation Systems (GIS) are tools that help us collect, analyze, and visualize geographic data. They combine maps with data to provide insights about locations and patterns. GIS can be used in various fields, such as urban planning, environmental management, and transportation, allowing users to make informed decisions based on spatial information. GIS technology includes software and hardware that enable users to create detailed maps and perform spatial analysis. By integrating data from sources like satellite imagery and surveys, GIS helps in understanding complex relationships in the environment, making it essential for research, planning, and resource management.
