The place layer consists out of [countries](http://wiki.openstreetmap.org/wiki/Tag:place%3Dcountry),
|
|
|
|
|
[states](http://wiki.openstreetmap.org/wiki/Tag:place%3Dstate) and [cities](http://wiki.openstreetmap.org/wiki/Key:place).

|
Apart from the roads this is also one of the more important layers to create a beautiful map.
|
|
|
|
|
We suggest you use different font styles and sizes to create a text hierarchy.
|
|
|
|
|
fields:
|
|
|
|
|
name: The OSM [`name`](http://wiki.openstreetmap.org/wiki/Key:name) value of the POI.
|
|
|
|
|
name_en: The english `name:en` value if available.
|
|
|
|
|
class: |
|
|
|
|
|
Distinguish between `country`, `state` and other city classes like
|
|
|
|
|
`city`, `town`, `village`, `hamlet`, `suburb`, `neighbourhood` or `isolated_dwelling`.
|
|
|
|
|
Use this to separately style the different places according to their importance (usually country and state different
|
|
|
|
|
than cities).

|
Countries, states and the most important cities all have a `rank` to boost their importance on the map.
|
|
|
|
|
The `rank` field for counries and states ranges from `1` to `6` while the `rank` field for
|

|
|
|
cities ranges from `1` to `10` for the most important cities and continues from `10` serially based
|
|
|
|
|
on the local importance of the city (derived from population and city class).
|
|
|
|
|
Use the `rank` field to build a text hierarchy.
|
2016-10-29 12:29:41 +00:00
|
|
|
The rank value is a combination of the Natural Earth `scalerank`, `labelrank` and `datarank` values for countries
|
2016-10-29 12:49:53 +00:00
|
|
|
and states and for cities consists out of a shifted Natural Earth `scalerank` combined with a local rank
|
|
|
|
|
within a grid for cities that do not have a Natural Earth `scalerank`.
