A geographic information system (GIS) is a framework engineered to capture, store, manipulate, analyze, manage, and present spatial or geographic data. The term GIS is also occasionally employed to denote geographic information science (GIScience), which refers to the academic discipline investigating these systems and represents a significant domain within the broader field of geoinformatics.
QGIS operates as geographic information system (GIS) software, enabling users to analyze and edit spatial data, as well as compose and export graphical maps. It supports both raster and vector layers, with vector data stored as point, line, or polygon features. The software accommodates various raster image formats and offers image georeferencing capabilities. In summary, it empowers users to create, edit, visualize, analyze, and publish geospatial information across Windows, Mac, Linux, and BSD platforms.
In its initial phase, this program introduces the QGIS interface for general usage. The second phase covers PyQGIS—the Python libraries of QGIS—which allows the integration of GIS functionalities into your Python code or applications, enabling you to develop custom Python Plugins for specific GIS features.
