+## Address
+<!-- {: .d-inline-block } -->
+
+A selection of [osm tags](https://wiki.openstreetmap.org/wiki/Map_features#Building) are simply copied to the 3D Building Models verbatim; with the exception of the address. To reduce the complexity of the osm [Key:addr](https://wiki.openstreetmap.org/wiki/Key:addr#Detailed_subkeys) each component is concatenated into one [string](https://en.wikibooks.org/wiki/Python_Programming/Variables_and_Strings#String) following, as closely as possible, the [ISO 19160-1:2015(en) Addressing](https://www.iso.org/obp/ui/#iso:std:iso:19160:-1:ed-1:v1:en) standard. A typical address will thus read: `housenumber street suburb postalcode city province`. If the [Key:addr:flats](https://wiki.openstreetmap.org/wiki/Key:addr:flats) is present the unit range will prepend the address.

+## Google Plus Codes
+
+Google ['plus codes'](https://maps.google.com/pluscodes/) are included at a precision of [11 characters - 3.5-meter block size](https://en.wikipedia.org/wiki/Open_Location_Code) (e.g. 4FRW3J9R+892Q); referenced to the [`representative_point()`](https://shapely.readthedocs.io/en/stable/manual.html) of buildings.
+
+<!--## Streets
+{: .d-inline-block }
+
+*Right now; streets are only available with [village/campus](https://github.com/AdrianKriger/osm_LoD1_3DCityModel/tree/main/village_campus).* 
+
+Similar to [Key:addr](https://wiki.openstreetmap.org/wiki/Key:addr#Detailed_subkeys); the osm [Key:highway](https://wiki.openstreetmap.org/wiki/Key:highway) are simply copied to the [CityJSON Transportation Object](https://www.cityjson.org/specs/1.1.2/#transportation).
