This chapter will provide you with an overview of the Graphical Modeler (GM). First, we will introduce the modeler and explore the various inputs and algorithms available for models. Then, we will demonstrate via step-by-step examples how to develop a model that can be added to the Processing Toolbox. We will also cover more advanced topics, including nesting models and executing models interactively. The specific topics that we will cover in this chapter are as follows:
- An introduction to the graphical modeler
- Working with your model
- Executing model algorithms iteratively
- Nesting models
- Using batch processing with models
- Converting a model into a Python script
