  • 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 commands and functions to get results or data we might be looking for. This can be achieved using Python as QGIS supports user-defined expressions and functions written in the popular programming language. These functions can be used on QGIS's Python console. And for certain tasks, we need to compare different data sets, which requires the repetition of the same functions. And is there a better way to do this? QGIS offers the capability to easily automate user tasks using scripts.

This workshop gives an overview of Python programming in QGIS (PyQGIS), the Processing framework, before teaching more in-depth, with hands-on examples, into how to automate tasks using Python scripts and Graphical Modeler(overview?), 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 create custom scripts for their own analysis.
