Automate QGIS with PyQGIS

Overview

This course helps data analysts move beyond manual, point-and-click GIS workflows by introducing practical automation with PyQGIS. Learners work directly inside QGIS to understand the PyQGIS API, write a Python script that buffers road features by 500 meters, and execute that script to produce saved outputs ready for weekly safety reporting. Through short videos, readings, coach dialogues, hands-on activities, and scenario-based assessments, learners practice translating familiar GIS tasks into reusable code. The emphasis is on clarity, repeatability, and trust ensuring automated analyses behave consistently and can be explained, reviewed, and reused over time. By the end of the course, learners can confidently replace a manual buffer workflow with a dependable PyQGIS script that supports real operational reporting.

Syllabus

Understanding the PyQGIS API Structure

Learners explore how PyQGIS is organized and how Python interacts with QGIS objects. The focus is on understanding layers, features, geometries, and the processing framework so scripts are readable and maintainable.

Writing a PyQGIS Script to Buffer Roads

Learners write a Python script that buffers road features by 500 meters using PyQGIS processing tools. Emphasis is on correctness, parameters, and reproducibility.
