[OSM-newbies] Is building=yes (or landuse=retail) necessary in addition to amenity=fuel?

[Severin MENARD]

Hi,

For building=yes, I would say it is not really a matter of rendering
(tagging for a specific rendering is not a good rule) but more the most
generic tag used to identify a building, whatever his function, type, etc.

For the "using a node or not to specify the activities inside a building"
there are 2 schools. Tagging the building has a limit cause you put only
one amenity=* or shop=* and there are lot of buildings hosting more than
one, so some people tag the building area when there is only one activity
or shop and use nodes if there are more. Other people (I am in) think it is
better to put all these activities on nodes and the buildings are described
for their own physical features like materials, condition, etc. rather then
see them dispatched in two different logics and topologies.


Sincerely,

Severin
