Proposal

This proposal aims to describe places where huge events happen, like exhibition halls, exposition centres, convention centres, and conference centres. They host regional, national or international events. They have dedicated buildings and services.
We distinguish two categories :
- Exposition centre : also known as exhibition hall, it's one or more buildings with an area between 5000 and 100000 m2. These buildings have a flat and contiguous floor, and provided equipments are moveable. They are located around cities, in order to be able to receive a huge amount of visitors (thousands of visitors). They host all kind of events (professional shows, public demonstrations, sometimes cultural events, ...). Here are some examples.
- Conference centre : also known as convention centre, it's one building with several conference rooms, amphitheatres, meeting rooms, exhibition rooms and an hotel. They host professional or political events or fairs. This kind of event lasts for a few days, that's why there is an hotel. The amount of visitors is reduced (hundreds of visitors). Also some examples :
However, we frequently see some sites who belong to those two categories (Hong-Kong Convention and Exhibition Centre, San Diego Convention Center, ...).
Rationale
Currently, there is no clear description of this kind of objects. Some tags are used, but only on a few objects.
amenity=exhibition_centre
amenity=exhibition_center
amenity=exposition_centre
amenity=convention_centre
tourism=convention_center
amenity=exhibition_hall
amenity=community_centre
in some cases, but it's not the goal of this tag.
Moreover, there is a confusion between the different kinds of events centre. The idea is to create a comprehensive tag to make it simple to describe.
Tagging
To tag events centre, two situations :
- When there are no other choices (low-quality imagery), put a
node on the estimated centre of the object. Put the tag
amenity=events_centre
on it. - When it's possible, we will describe events centre with an
area.
- If the events centre is a single building, put
amenity=events_centre
on the building area. Also addbuilding=*
to know that it's a building and not a land area. - If the events centre contains several buildings, create an area to describe the whole site. Put
amenity=events_centre
on this area. It's not necessary to add the events_centre tag on each building in the area.
- If the events centre is a single building, put
Then, you may precise the kind of events centre, to do this use events_centre=*
:
events_centre:exhibition=yes
for exposition/exhibition centres.events_centre:conference=yes
for conference/convention centres.- Both when the site can do both.
Additional tags
To describe further the events centre, you can add those tags.
name=*
: the name of the centre, for example San Diego Convention Centeroperator=*
: the name of the company which manages the centrecontact=*
: contact details
Objects in the events centre area
Some features can be commonly found in events centre.
Examples
The scheme in this proposal has been applied on some examples.
- Exhibition centres
- Parc expo Rennes aéroport
Parc expo Rennes aéroport : an exhibition centre in France (as a land polygon), which also hosts some cultural events.
- Le Chorus de Vannes
Le Chorus de Vannes : a smaller exhibition centre in France (as a site relation).
- Parc expo Rennes aéroport
- Conference centres
- Palais des Arts et des Congrès de Vannes
Palais des Arts et des Congrès de Vannes : a conference centre in France (as a single building), which also hosts cultural events.
- Palais des Arts et des Congrès de Vannes
Features affected
As this kind of object is not really described, no feature is really affected. A wiki page will be created to document this tag.
Comments
- Use exhibition instead of exposition as
events_centre=*
sub-key, as the term is already used in OSM.
