Welcome to the QGIS Python API documentation project

Introduction

QGIS is a user friendly Open Source Geographic Information System (GIS) that runs on Linux, Unix, macOS, and Windows. QGIS supports vector, raster, and database formats. QGIS is licensed under the GNU General Public License. QGIS lets you browse and create map data on your computer. It supports many common spatial data formats (e.g. ESRI ShapeFile, GeoPackage, PostGIS, geotiff). QGIS supports plugins to do things like display tracks from your GPS. QGIS is Open Source software and it is free of cost (download here). We welcome contributions from our user community in the form of code contributions, bug fixes, bug reports, contributed documentation, advocacy and supporting other users on our mailing lists and forums. Financial contributions are also welcome.
