You can generate BBOX with many online tools:

One example:

- go [http://geojson.io](http://geojson.io)
- Draw a rectangle ( around the city )
- call the menu : **“Meta”/“Add bboxes”**
- on the GeoJSON part: you will find the “bbox” coordinates.

like this ( Roma/Italy)

```julia
       "bbox": [
          12.368545532226562,
          41.794864268833145,
          12.623291015625,
          41.99011884096809
        ]

```
