vertical depth edit

Originally proposed at Wikidata:Property proposal/Generic

Done: vertical depth (P4511) (Talk and documentation)

Description	vertical distance from a horizontal area to a point below
Represents	depth (Q930412)
Data type	Quantity
Example	Dead Sea (Q23883) → depth → 298 meter 2004 Indian Ocean earthquake (Q130754) → 30km
Robot and gadget jobs	yes, if both height above sea level and deepest point is set
See also	Quantity datatype: elevation above sea level (P2044), height (P2048), width (P2049), length (P2043) Item datatype: lowest point (P1589)

Motivation

Impractical to set deepest point for lakes with surface above sea level, which counts for most lakes. Depth will be the difference between elevation above sea level and deepest point. – The preceding unsigned comment was added by Event (talk • contribs) at 17:32, September 6, 2017‎ (UTC).

Discussion

@Event: your example doesn't make sense; I assume the value for this property should be generally in units of meters or some other length dimension. Can you describe how this property would differ from height (P2048) (for vertical dimensions) and width (P2049) (horizontal)? ArthurPSmith (talk) 17:19, 8 September 2017 (UTC)[reply]

ok, the example is fixed now. However the description refers to two different things, do you have an example of the second definition (horizontal distance from a vertical surface)? Or should we perhaps limit this property to just the vertical dimension? ArthurPSmith (talk) 15:15, 11 September 2017 (UTC)[reply]

I have been thinking about cupboard and cabinet depths, but not sure about need for it.

Comment. I think elevation above sea level (P2044) can have a negative value (some lowest point (P1589) are qualified with that), but in general P2044 is meant for the highest point.
As for cupboards, I think the use of some other property was advocated.
I think it would be preferable to limit this to your initial usecase. Properties that are defined in a too generic way tend to become messy.

I'm not sure what is the difference between depth and height? We can just add depth as "also known as" to the height property no? Amqui (talk) 02:52, 6 October 2017 (UTC)[reply]
See also focal depth - @Event, GZWDer: ok if we combine these? The example there of an earthquake would be good as a second example here I think. ArthurPSmith (talk) 12:22, 19 October 2017 (UTC)[reply]
Support Combine with focal depth and also to be used for horisontal distances, depth is often used as term for horizontal Caves. Breg Pmt (talk) 23:43, 8 November 2017 (UTC)[reply]
Comment maybe the two uses should have separate properties: (vertical distance from a horizontal area to a point below) and (horizontal distance from a vertical area to an inner point).

I agree with Jura, those two seem to me to be different and there's no good reason for merging them. ChristianKl (talk) 16:02, 10 November 2017 (UTC)[reply]
That's fine, both of the examples are vertical distance, nobody came up with a concrete horizontal example (and when I search on "depth" for caves that seems to always refer to vertical distance also) so I do believe this is ready to go with regard to the vertical distance case. I've adjusted the proposed description and marked as ready again. ArthurPSmith (talk) 20:02, 10 November 2017 (UTC)[reply]
- Shall we call it "vertical depth"? In some languages (including English), "depth" is ambiguous.

I agree that "vertical depth" is a better name and renamed it correspondingly. ChristianKl (✉) 18:28, 11 November 2017 (UTC)[reply]
