I still do not think man_made=surveillance is perfect. But I do
not have huge problems with it as long as it is documented.
If something is properly documented in OSM it is a near to perfection
as it will ever get ;-)
I also think that surveillance does make sense in this context.
But if I kindly refer you to
http://wiki.openstreetmap.org/wiki/Tag:man_made%3Dsurveillance ,
you will see that it talk about Big Brother, not about webcams. It
does not even define how to link to a image on internet.
Have a look at
http://wiki.openstreetmap.org/wiki/Proposed_features/Key:Surveillance
man_made=surveillance
surveillance=webcam
contact:webcam=<url>
Seems fine to me.
So when only a few hundred webcams displaying landscape are mapped
in the world, I would say there is a real problem that people do
not know how to map them.
Or that not a lot are interested in tagging them. Everyone has
different interests - I don't think I would ever map a webcam. But I
do map fire hydrants... sometimes ;-)
Best regards,
Martin

OK, webcam is surveillance then.
I am not sure about surveillance=webcam, current values are
indoor|outdoor|public, which I think is orthogonal to being a webcam.
contact:webcam=<url> is fine, that tell we have a webcam. Do we really
need anything more to tell its a webcam?
Taginfo lists 171 contact:webcam , only 53 url:webcam, so contact:webcam
has a lead.
surveillance:zone=weather|traffic|scenic as mentioned elsewhere in the
thread seem to me like a good idea.
Should it be allowed with a list of surveillance:zone values, like
surveillance:zone=scenic;town or surveillance:zone=scenic;snow ?
So my revised suggestion to tag a webcam public on internet is
man_made=surveillance
surveillance= indoor|outdoor|public *
surveillance:type=camera *
surveillance:zone=weather|traffic|scenic *
contact:webcam=<url>
name=*
operator=*
description=*
camera:direction= compass degrees *
camera:angle = horizontal angle of view *
* means optional
In order to handle the
http://wiki.openstreetmap.org/wiki/Talk:Proposed_features/Extended_tags_for_Key:Surveillance#more_than_one_camera_mouted_on_a_pole
case I
suggest make each camera as a relation, the only member is the location
node. The location node could be a man_made=mast.
The relation could be tagged as type=surveillance, in combination with
the tags mentioned above.
