In OpenMapTiles, shield information is encoded in the [`transportation_name`](https://openmaptiles.org/schema/#transportation_name) vector tile layer with a series of attributes named `route_1`, `route_2`, etc. Each attribute contains a text string which contains all of the information needed to determine which graphic to display, including numeric route number if the shield is numbered. However, this library allows you to specify how the shield information has been encoded, and it's possible to stitch together data from multiple fields when encoding shield data.

 In addition to the stock drawing functions, a custom draw function can be specified. `paDot` and `branson` are included as examples of this, for rendering the [Allegheny County belt system](https://en.wikipedia.org/wiki/Allegheny_County_belt_system) and the Branson, Missouri colored route system. See the file `src/custom_shields.mjs` for an example of how this is done.
