About the Processing Toolbox
The Processing Toolbox serves as a one-stop-shopping GUI for accessing algorithms from both native QGIS tools and many third-party providers. Historically, the algorithms from other geospatial packages were only accessible within the native software environment or through a command-line environment. Algorithms from the following providers are accessible using the toolbox:
QGIS geo-algorithms
GDAL/OGR
GRASS
SAGA
TauDEM
LAStools
Fusion
R
Orfeo Toolbox
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 QGIS Plugins with PyQGIS and Problem Solving, respectively.
Configuring the Processing Toolbox
In this section, we will ensure that the Processing Toolbox is correctly configured...
