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 occasionally used to denote Geographic Information Science (GIScience), which refers to the academic field studying these systems, representing a significant area within the broader discipline of geoinformatics.
QGIS operates as 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; vector data is stored as points, lines, or polygons. The software accommodates various raster image formats and can georeference images. In summary, it allows users to create, edit, visualize, analyze, and publish geospatial information across Windows, Mac, Linux, and BSD platforms.
In the first phase, this program introduces the QGIS interface for general use. The second phase covers PyQGIS, which comprises the Python libraries of QGIS that facilitate the integration of GIS functionalities into your Python code or application, allowing you to develop custom Python plugins around specific GIS capabilities.
