|
|
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: English name `name:en` if available, otherwise `name`.
|
|
name_de: German name `name:de` if available, otherwise `name` or `name:en`.
|
|
capital:
|
|
description: |
|
|
The **capital** field marks the
|
|
[`admin_level`](http://wiki.openstreetmap.org/wiki/Tag:boundary%3Dadministrative#admin_level)
|
|
of the boundary the place is a capital of.
|

Original value of the

[`place`](http://wiki.openstreetmap.org/wiki/Key:place) tag.
|
|
Distinguish between continents, countries, states and
|
|
places like settlements or smaller entities.
|
|
Use **class** to separately style the different places and build
|
|
a text hierarchy according to their importance.

rank:
|
|
description: |
|
|
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).
|
|
You can use the **rank** to limit density of labels or improve
|
|
the text hierarchy.
|
|
The rank value is a combination of the Natural Earth
|
|
`scalerank`, `labelrank` and `datarank` values for countries
|
|
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`.
