The Processing Toolbox provides a one-stop-shop that helps you find the algorithms that not only belong to the QGIS tools, but also those belonging to some third party.
This initially allowed the algorithms that were QGIS natives and were a part of geospatial packages. They could be accessed only by using the software or through the command line. We can now access algorithms from the following providers using the Toolbox:
- QGIS geo-algorithms
- GDAL/OGR
- GRASS
- SAGA
- R
- Models
- Scripts
We will not make use of all the algorithm providers or explore all the available algorithms in this chapter; however, the last two entries in the list offer additional options for creating reusable graphical models and running Python scripts, which are covered in Chapter 9, Automating Workflows with the Graphical Modeler, and Chapter 10, Creating...
