QGIS for Mac is the macOS version of QGIS (Quantum GIS), a free and open-source geographic information system (GIS) software application. It provides users with a powerful and versatile set of tools for creating, editing, visualizing, analyzing, and managing geospatial data. Essentially, it[SQ]s the same robust QGIS software as available for Windows and Linux, but specifically compiled and packaged for Apple[SQ]s operating system. It allows Mac users to work with various spatial data formats, perform geoprocessing tasks, create maps, and much more, all without the cost associated with commercial GIS software.
