Workshop QGIS Python GeoPython 2018: Unterschied zwischen den Versionen

Version vom 13. Februar 2018, 18:23 Uhr

• 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 result in data we might be looking for. This can be done, and as we know, because QGIS supports user-defined expressions and functions written in the popular Python programming language. These functions can be used on QGIS's Python console, and opens up the capability to easily automate user tasks.

This workshop gives an overview of Python programming in QGIS (PyGIS), talks about the Processing framework, before teaching more in-depth, with hands-on examples, into how to automate tasks using Python scripts, Graphical Modeler(?) and plugins(?), 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 also to create scripts to automate tasks in QGIS Version 3.
