  • Workshop about QGIS Processing Framework: Automating Tasks with Python
  • by Prof. Stefan Keller and Kang Zi Jing, Geometa Lab at HSR Rapperswil
  • 7 May, 2018, Basel/Muttenz, https://2018.geopython.net/

When analyzing geospatial data, we sometimes need to invoke certain methods and functions to get results or data we are looking for. This can be achieved using Python, as QGIS supports user-defined expressions and functions written in the popular programming language on QGIS's Python console (PyQGIS). We need to compare different data sets for certain tasks, which requires calling the same functions repeatedly. So, is there a better way to do this? PyQGIS is the answer to easily automate user tasks using Pythonic scripts.

This workshop gives an overview of Python programming in QGIS (PyQGIS), QGIS' Processing framework, before in-depth, with hands-on examples, explanations on how to automate tasks using Python scripts, which would otherwise require repetition of the same process/running of code.

This session concludes with how users can use these skills under the Processing framework, and to use and create custom scripts for their own data analysis.
