Layers defined in this theme configuration file

These layers can not be reused in different themes.

osm_buildings

Layer showing buildings that are in OpenStreetMap

• This layer is shown at zoomlevel 18 and higher
• Not rendered on the map by default. If you want to rendering this on the map, override mapRenderings

No themes use this layer

Basic tags for this layer

Elements must match the expression building~.+

Execute on overpass

Supported attributes

Warning:,this quick overview is incomplete,

attribute	type	values which are supported by this layer
ref:bag	Multiple choice
building	string

Reference

This tagrendering has no question and is thus read-only The reference in BAG is {ref:bag}

• This building has no reference in the BAG is shown if with ref:bag=

Building type

The question is What kind of building is this? This building is a {building} is shown if building is set

leftover-questions

This tagrendering has no question and is thus read-only {questions( ,)}

lod

This tagrendering has no question and is thus read-only {linked_data_from_website()}

This tagrendering has labels added_by_default

osm_adresses

Layer showing adresses that are in OpenStreetMap

• This layer is shown at zoomlevel 18 and higher

No themes use this layer

Basic tags for this layer

Elements must match all of the following expressions:

0. source=BAG
1. addr:city~.+
2. addr:housenumber~.+
3. addr:postcode~.+
4. addr:street~.+

Execute on overpass

Supported attributes

lod

This tagrendering has no question and is thus read-only {linked_data_from_website()}

bag_pand

Buildings from BAG register

• This layer is shown at zoomlevel 18 and higher
• 

This layer is loaded from an external source, namely

This tagrendering has no question and is thus read-only

The overlapping osm_buildings is a {_osm_obj:building} and covers {_overlap_percentage}% of the BAG building.
The BAG-building covers {_reverse_overlap_percentage}% of the OSM building

BAG geometry:

{minimap(21, id):height:10rem;border-radius:1rem;overflow:hidden}

OSM geometry:

{minimap(21,_osm_obj:id):height:10rem;border-radius:1rem;overflow:hidden}
