In one file or layer-to-many batch parameter sets processing, Modeler processes the same input file or layer with different batch parameter sets, which you define on a module's control panel.
Figure 1. One file or layer-to-many batch parameter sets
Input file or layer processing sequence
Modeler applies the first batch parameter set to the input file or layer and then stores the result in the first output file. Next, Modeler applies the second batch parameter set to the input file or layer and stores the result in the second output file or appends it as a layer. This process continues until all batch parameter sets have are applied.
