Introduction:
This article is a submission from the adorable Nannan♂ of 【DianDian GIS】, which has been sitting with me for half a month. If I don’t publish it soon, he might kill me. So without further ado, here is his article~
The original intention of writing this article was that manual clipping was too exhausting when clipping OSM, and I wanted to find a lazy method. (Editor’s note: Is laziness really the ladder of technological progress?)01Model Diagram
First, here is the model. Since only one iterator can be added in each Model Builder, sub-model nesting is required.

02Model Details◐
Main Model
The main model is divided into three modules
Module 1:Create a file geodatabase (gdb) for each province and municipality.Module 2:Iterate through the selection of features from the administrative division (provincial level) data, using the selected features as input for the clipping sub-model’s “Clipping Features”; the “Iterative Feature Selection” iterator yields the “Value”, which corresponds to the district names (name field) in the administrative division feature data. Using inline variables, the names of each administrative division iterated will be used to name the created file geodatabase.Module 3:Input the clipping feature database as the iterative feature for the sub-model.

Sub Model
The sub-model is a classic batch clipping model that only clips feature classes under the GDB directory.
Figure 4｜Batch Clipping ModelSet the save path, osm.gdb, and input features as model parameters, thus adding the sub-model as a process to the main model. The parameters of the sub-model will automatically be added as variables in the main model.
Figure 5｜Clipping Tool InterfaceThe working interface of the clipping model is shown in the figure,

The model parameters are as follows

Run the main model, and the result is a GDB database named after each administrative division (due to the large data volume, I only ran a part of it and paused, which was taxing on my computer).

It is important to note that this model only clips directories under the gdb database, so the data to be clipped must be placed in the gdb database.
