Relation:areaAddress
Status: Proposed (under way)
Proposed by: Hno
Tagging: type=areaAddress
Applies to: WayRelation
Definition: areaAddress is a method to tag named squares, junctions, open fields and sites, in the whole areas, independently from the streets nearby.
Rendered as: text
Drafted on: 2012-04-08


Reason for this proposal

Sometimes houses have in the address instead of a street's name the name of an area. In most cases this area can be tagged by naming a way around with the area's name. But there can be exceptions, when the roads, the buildings belonging to the area can be reached by, are named differently. By this there are no roads tagged with highway=name of the area. Addresses with addr:street=name of the area can't be assigned to any highway.

These areas can be open fields or sites, but big named junctions can be tagged with this method as well.

For better understanding see also Examples.

Tagging

An areaAddress relation is made of two other relations:

  • an associatedStreet relation
  • a multipolygon

associatedStreet

The associatedStreet relation is used to connect the addresses with their access roads.

Tags

The tag type=associatedStreet is mandatory.

Other tags, including name=*, are not neccessary.

Members

Tag Number Role Description
Way highway=* one or more street The roads the houses with the area's address can be reached by; in use with junctions the road segments being part of the junction
Node Area addr:street=* house The addresses belonging to the area.

Multipolygon

The multipolygon relation is used to define the area.

Tags

The tag type=multipolygon is mandatory.

Other tags, including name=*, are not neccessary.

Members

Tag Number Role Description
Way any tags one or more Ways being part of the areas boundary

areaAddress

The areaAddress relation connects the houses and their access roads with the area.

Tags

Key Value Description Recommendation
type areaAddress Definition mandatory
areaAddress site an area with buildings of similar use (e.g. education, shopping) mandatory
open_fields an area outside of the residential area with a few buildings
junction a named junction
name any the area's name mandatory

Examples

Open fields #1

view in OSM

open fields Äußerer Pfühl
Tagging at the moment
The blue framed area are open fields called Äußerer Pfühl.
The orange coloured buildings have the area's address (e.g. "Äußerer Pfühl 17").
The red marked road is the orange buildings' access road. Although it is tagged with name=Äußerer Pfühl at the moment, the road itself has the name Buchernsteige.


Using the areaAddress relation
Relation Tags Role Members
associatedStreet type=associatedStreet street Red marked track, tagged with name=Buchernsteige
house Orange buildings, tagged with addr:street=Äußerer Pfühl
multipolygon type=multipolygon Elements of the blue boundary of the area
areaAdress type=areaAddress areaAdress=open_fields name=Äußerer Pfühl The associatedStreet and the Multipolygon relations

Open fields #2

view in OSM

open fields Frosch
Tagging at the moment
The blue framed area are open fields called Frosch.
The orange coloured buildings have the area's address (e.g. "Frosch 3").
The red marked road is the orange buildings' access road called Trappensee. By the fact that this road is the only orange buildings' access road, there is no highway tagged with name=Frosch.


Using the areaAddress relation
Relation Tags Role Members
associatedStreet type=associatedStreet street Red marked highway, tagged with name=Trappensee
house Orange buildings, tagged with addr:street=Frosch
multipolygon type=multipolygon Elements of the blue boundary of the area
areaAddress type=areaAddress areaAdress=open_fields name=Frosch The associatedStreet and the Multipolygon relations


Areas within residential areas

view in OSM

open fields Frosch

A more famous example is the city center of Mannheim

Tagging at the moment
The blue framed area is called Bildungscampus by the fact, that there are only buildings with educational use.
The orange coloured buildings have the area's address (e.g. "Bildungscampus 3").
The red marked roads are the orange buildings' access roads. They are all named differently.


Using the areaAddress relation
Relation Tags Role Members
associatedStreet type=associatedStreet street Red marked highways
house Orange buildings, tagged with addr:street=Bildungscampus
multipolygon type=multipolygon Elements of the blue boundary of the area
areaAddress type=areaAddress areaAdress=site name=Bildungscampus The associatedStreet and the Multipolygon relations

Junctions

view in OSM

open fields Frosch
Tagging at the moment
The blue framed area is the area of the junction called Adenauerplatz
The red marked roads are crossing the area. They all have the names of the roads around.


Using the areaAddress relation
Relation Tags Role Members
associatedStreet type=associatedStreet street Red marked highways crossing the area or being part of it's boundary
house none
multipolygon type=multipolygon Elements of the blue boundary of the area
areaAddress type=areaAddress areaAdress=junction name=Adenauerplatz The associatedStreet and the Multipolygon relations

Notes

The name of the area is shown in the middle of the multipolygon. Depending of the type of area the used font is different:

  • In use with open fields: bold letters
  • In use with sites: bold italic letters
  • In use with junctions: italic letters
