PyQGIS is the Python interface to QGIS. This site is intended to collect concise, production-minded material for scripting QGIS projects, extending the desktop app, and making spatial workflows easier to maintain.

Automation

Turn repeated GIS work into scripts

Capture the steps behind imports, layer cleanup, styling, exports, and reports so QGIS projects can be reproduced with less manual clicking.

Plugins

Build tools that live inside QGIS

Use PyQGIS and Qt to shape small, practical plugins for teams that need custom buttons, forms, validation, or data processing workflows.

Processing

Chain spatial analysis with confidence

Run native and provider algorithms from Python, pass parameters clearly, and keep the output path from raw data to final map easy to inspect.

Typical PyQGIS flow

From desktop task to repeatable process

  1. Load layers
  2. Clean attributes
  3. Run analysis
  4. Style maps
  5. Export results
