Re: [Tagging] Surveillance camera angle

btw., there is also the established "direction" tag which defines cardinal
directions and angles. Is there a reason we need a different tag for
cameras?

Admittedly, 80% are about "forward" backward, both and clockwise:

But at least the specification is clear:

I guess, "angle" assumes that North is at 0 and that the angle is measured
clockwise? Generally I agree that this is underspecified. It may also not
be recognizable whether the camera can be rotated or is fixed. Field of
view may be even harder to recognize. So in general you can expect that all
this information will be relatively unreliable ;-)

[Tagging] Surveillance camera angle

2020-06-29 Thread Cascafico Giovanni
Hello!

What is "camera:angle"?

Taginfo [1] lists values consistent both to field-of-view and
inclination. I cannot find wiki, just discussion and a proposal status
[2].
