[Points of interests](http://wiki.openstreetmap.org/wiki/Points_of_interest) containing

a of a variety of OpenStreetMap tags. Mostly contains amenities, sport, shop and tourist POIs.

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`.
|
|
class: |
|
|
More general classes of POIs. If there is no more general `class` for the `subclass`
|
|
this field will contain the same value as `subclass`.
|
|
But for example for schools you only need to style the class `school` to filter the subclasses `school`
|
|
and `kindergarten`. Or use the class `shop` to style all shops.
|
|
subclass:

Original value of either the
|
|
[`amenity`](http://wiki.openstreetmap.org/wiki/Key:amenity),
|
|
[`leisure`](http://wiki.openstreetmap.org/wiki/Key:leisure),
|
|
[`landuse`](http://wiki.openstreetmap.org/wiki/Key:landuse),
|
|
[`railway`](http://wiki.openstreetmap.org/wiki/Key:railway),
|
|
[`station`](http://wiki.openstreetmap.org/wiki/Key:station),
|
|
[`sport`](http://wiki.openstreetmap.org/wiki/Key:sport),
|
|
[`tourism`](http://wiki.openstreetmap.org/wiki/Key:tourism)
|
|
or [`shop`](http://wiki.openstreetmap.org/wiki/Key:shop)
|
|
tag. Use this to do more precise styling.
|
|
rank: |
|
|
The POIs are ranked ascending according to their importance within a grid. The `rank` value shows the
|
|
local relative importance of a POI within it's cell in the grid. This can be used to reduce label density at *z14*.
|
|
Since all POIs already need to be contained at *z14* you can use `less than rank=10` epxression to limit
|
|
POIs. At some point like *z17* you can show all POIs.
