Choose all the files of a folder as an input to run a process in the model designer in QGIS

Question

I hope you can help me with this. I have this in the model designer and I looking for a solution because I need to run this process in many layers (150) and I dont know if is possible to select a folder and all the files as inputs.

Answer 1

You can execute the model as a batch process.

Press Run model and:

I select all files with 72 in the name in this folder:

The tricky part is to name the outputs. This expression replaces the input path with C:/TEMP/model_outputs and use input file name and appends _output.tif to the output file name (use forward slashes in path). Replace @input_raster_layer to match your input parameter name (yellow input box in first screenshot):

 concat(
 replace(
 file_path( @input_raster_layer ),
 file_path( @input_raster_layer ),
 'C:/TEMP/model_outputs'),
  concat('/',
  base_file_name(@input_raster_layer), '_output.tif'))
