open-source GIS

Open-source GIS (Geographic Information System) refers to software that allows users to create, analyze, and visualize geographic data, which is available for anyone to use, modify, and share without licensing fees. Unlike proprietary software, open-source GIS fosters collaboration and innovation by enabling developers and users to contribute to its improvement. This democratizes access to powerful mapping and spatial analysis tools, making them accessible for researchers, governments, and businesses alike. Popular examples include QGIS and MapServer, which serve diverse applications, from urban planning to environmental monitoring.
