This is the direction into which the camera is pointed?


> GST_TAG_GEO_LOCATION_MOVEMENT_DIRECTION (same).

Makes sense, but in what scenario is this interesting in a multimedia context?
When snapshotting/filming out of a train window or something? Or just for
completeness sake?

Agreed. I'd go for m/s, it seems more 'neutral' and natural.

The DOP might also be of interest, as an indication how precise the
lat/long/elev values are, but maybe that value is too GPS-specific?
