The QGIS Model Designer is a powerful tool that we can use to define a workflow and run a chain of algorithms (a processing model). In this workshop we will create a processing model in the QGIS Model Designer and learn how to effectively use some of the features.
A normal session with the processing framework tools includes more than running a single algorithm. Usually several of them are run to obtain a result, and the outputs of some of those algorithms are used as input for some of the other ones. Using the QGIS Model Designer, that workflow can be put into a processing model, which will run all the necessary algorithms in a single run, thus simplifying the whole process and automating it. In this workshop we will create a processing model in the QGIS Model Designer that displays buildings affected by some event within a distance from an event location. The affected buildings are determined by: - Clicking a point on the map canvas to define an event location, - Traveling a distance along the road network from the event location, - Buffering the travel distance to intersect land parcels, - Extracting building footprints that that intersect the land parcels. **Prerequisite skills:** - Attendees should have some familiarity with QGIS **Preparation required:** - Laptop - QGIS LTR or 3.32+ installed https://www.qgis.org/en/site/ **Book your ticket here:** https://ti.to/osgeo-oceania/foss4g-sotm-oceania-2023-workshops. *A total of 25 spaces are available.*
