I don't know if there's a best practice, but two options that come to mind:

* Bounding box and centrepoint (as with a map); this has the disadvantage that it covers a lot of area and none of the coordinates listed might actually be anywhere near the ones seen on the film! On the other hand, it's certainly best for, say, a long series of S-shaped sampling tracks back and forth. (I should know what these are called)

* An arbitrary point (say, midpoint of track) with other coordinates listed - say, start, end, points of particular interest. I'm not immediately sure if anything picks up coordinates mentioned in the file description, but at least they're there for future use as and when such tools appear.

Take me off these spam lists. Since editors arent wanted on the wmf projects and the wmf wants to enable bully behavior by admins I dont want to be spammed with this crap anymore.

Subject:[Commons-l] Co-ordinates for a path

All,

I have some videos of the seabed of the Dogger Bank, which includes some footage of wrecks on the bed, marine life, and parts of prehistoric settlements.

I have the exact co-ordinates of the videos - however, because it's a video, the co-ordinates change over time, and the moving co-ordinates of the file can't really be entered into Commons - or can they?

Can anyone help with this? *

What's the best way to record the co-ordinates if they move over the duration of the video?*

As yet there's no data structure defined in Wikidata for lists of things -- eg lists of coordinates.

This is something that is recognised as needed, eg to record the boundaries of administrative areas.

However, WD would in any case only store such data for something that was WD-notable -- not a GPS trace for a video, because the video wouldn't have a Wikidata item.

In future however such a video would have an item in the analogous CommonsData system that's planned, and that's somewhere it might well make sense to record a stream of co-ordinates.

A separate issue would be that the co-ordinates would ideally be linked to particular time-points in the video. I don't think anyone has yet done any much thinking about how the system in general would need to be extended to time-based information. Perhaps all it needs it is to simply create lots of different statements, each with a qualifier indicating the relevant time. (As one might have, eg to state different subjects shown in the video). In which case one might not need a single list-like vector item after all, just a lot of separate statements.
