A Geographic Information System (GIS) is a framework built to capture, store, manipulate, analyze, manage, and present spatial or geographic data. The term GIS is also used to refer to Geographic Information Science (GIScience), which is the academic discipline focused on the study of geographic information systems, representing a significant domain within the broader field of geoinformatics.
QGIS operates as GIS software, enabling users to analyze and edit spatial information, as well as compose and export graphical maps. It supports both raster and vector layers; vector data is stored as points, lines, or polygons. The software handles multiple raster image formats and can georeference images. In summary, it allows users to create, edit, visualize, analyze, and publish geospatial information on Windows, Mac, Linux, and BSD.
In its first phase, this program introduces the QGIS interface for general usage. In the second phase, we introduce PyQGIS, the Python libraries of QGIS, which allow you to integrate GIS functionalities into your Python code or applications, even enabling you to create your own Python plugin around specific GIS functionalities.
