Not sure what you mean by  “the software” but the Renderer’s designers choose 
what is displayed by the Renderer.  The standard OSM rendering of the OSM 
database shows objects that are marked as access=private as well as access=yes. 




As mentioned below only Public objects should be added to the DB unless they 
are physically noticeable such as private roads or property and they will be 
given an access tag of private to show they are not public.  access=private 
indicates the right of access to an object not that the object should be kept 
hidden from public disclosure.


Everything in OSM is visible to all Renderer's to display or not display aas 
they choose.


The OSM database is not the place for private individuals or organisations to 
store private data.


Hope this helps to clarify things.

What I mean is, does the software allow you to specify that only objects with 
access permitting the general public, or access=private with only specified 
values of the operator tag, be rendered?

Not sure what you mean by “Private Objects”, anything in the DB is capable of 
being displayed, depending on whether the Renderer wants to.  Nothing is 
Private in OSM.

Does the default rendering on the slippy map on OSM's main page show private 
objects? If it does, then there is a loss of privacy. If it doesn't, then there 
is a loss of feedback to mappers.

Examples not to map: toilets in homes, employee only toilets in businesses, 
private recycling bins, playgrounds in private homes or day care facilities.




Examples to map: toilets inside DisneyLand, buildings visible from air photos, 
private facilities with a history of public "permissive" use.



If OSM encourages others to use the OSM data base.. why cannot they add data 
that is 'private' to them? 

If renderers were not to render any access=private object then the general 
public would not be aware of these 'private' objects and 
those who want them may enter them and configure there own render to show 
'their' data alongside OSM data. 

One idea is to only map stuff that is 'publicly viewable'. Some define this as 
'from a public place' such as a street. However with satellite views being 
publicly available then mapping things that are not viewable from a public 
street becomes possible with more accuracy than that of a visual estimation 
from a public street. 

I think that mapping stuff that is not usefull, in some way, is a waste of 
time, public stuff or private stuff. If a person with authority wants to map 
private stuff .. then I think that is OK. The key is the authority.  

And then the definition of 'private' is? 
Are Universities 'private'? Are bicycle repair stations inside university 
grounds private?  
Are private swimming pools in backyards to be mapped as they may be used in an 
emergency to fight fires? 
The boundaries between private and public are grey ... and then their is 
community emergency use. Murky waters.
