A single "gazetteer" in this project is a collection of places that are thematically related or relevant to a particular map styling task. Keeping the content of a gazetteer focused and clearly defined will help map designers pick suitable gazetteers for reviewing their map styling projects.
A gazetteer is a json file which conforms to the gazetteer spec.
You can contribute by either adding new places to an existing gazetteer file, or adding a new gazetteer file.
Typically, you’ll want to pick places that clearly display either:
- A single map feature (e.g. a tunnel)
- A cluster or group of map features (e.g. several tunnels, surface roads, and bridges)
- Map features that interact with each other (e.g. a tunnel under a park)
- Is it famous or notable?
- Is it relatively permanent and stable?
- Is it one of the following?
- An archetypal example of a map feature or map feature interaction?
- An extreme example of a map feature or map feature interaction (in size, density, etc)?
- An unusual example of a map feature or map feature interaction (in shape, location relative to other features, etc)?
- Do you have reliable ground truth information?
Refer to the gazetteer spec for properties available to each place entry.
Choose a name that is as specific as possible to the map feature(s) displayed. For context, it is often helpful to also include the place or geographic feature that encompasses the specific map feature, e.g. “Jane Byrne Interchange, Chicago", “Central Park, New York City”, or "New York City, United States".
Prefer integer zoom levels between 0-22

Optional value between 0-60.
Optional value. Explain why this particular place is significant in the context of this gazetteer.
Optional value. Include arbitrary value tags to capture useful distinctions between places that are not already represented in the data-specific information.
