Hello. I'm Javier García Prieto from México. I do exactly the same as you intend to do years ago.
There are 2 ways to do what you want frim my perspective. 1 If you are working in Linux do a bash script to import every raster to grass, then execute your model from that script. https://thedbadmin.com/how-to-loop-in-bash-linux-shell-script-automation/ https://grasswiki.osgeo.org/wiki/Importing_data#:~:text=Create%20a%20new%20location%20for,raster%20data%20(internally%20using%20GDAL) 2 Use Python to do the same in a way that the script is system agnostic. Once you have aquired your maps in grass use your model as described above. Greetings from Mexico.

I have 456 raster layers that I (1) want to interpolate using v.surf.bspline, and then (2) export to six different folders, 76 rasters for each. I have designed the workflow in the graphical modeler using just one layer to see that everything works the way that it should, and it does! However, I can't for the life of me figure out how to set up a loop so that it can iterate through all the remaining layers. I'm trying my best to read the manual, but since all of this is new to me, I can't figure out (1) how to add several raster layers. Whenever I use the "add data to model" I can only add one layer from the drop down list. I also don't know if I need two loops, one for interpolation and then one for the raster export. I have attached a screenshot that outlines my model. I hope you'll be able to guide me in the right direction! Best, Victor [cid:50d4456d-7068-4914-87ef-b733b6be741a]
