A Geographic Information System (GIS) is a framework engineered to capture, store, manipulate, analyse, manage, and present spatial or geographic data. The term GIS is occasionally employed to denote Geographic Information Science (GIScience), which refers to the academic discipline dedicated to the study of such systems, representing a significant domain within the wider field of geoinformatics.
QGIS operates as GIS software, empowering users to analyse and edit spatial information, as well as create and export graphical maps. It supports both raster and vector layers; vector data is stored as point, line, or polygon features. The software accommodates various raster image formats and can georeference images. In essence, it enables users to create, edit, visualise, analyse, and publish geospatial information across Windows, Mac, Linux, and BSD platforms.
In its initial phase, this programme introduces the QGIS interface for general usage. During the second phase, we introduce PyQGIS—the Python libraries of QGIS—which facilitates the integration of GIS functionalities into your Python code or applications, allowing you to develop custom Python plugins around specific GIS capabilities.
