There would seen to be two distinct cases here (or maybe there is
more gray area).
1) The object being described has a direct relationship or attachment
to another object. That is the object only exists in a position
because of the presence of another object.
Examples: Man on horse, Sword wielded by Bubba, Book on table,
Bookmark inside book, etc.
2) The object being described has only a casual
positional relationship to other objects in the viewing area.
Your wagon example appears to be of this type.

The man, the horse and the wagon and the barge could be described
using case 1 above since they are all "attached" to each other. The
relationship of the towing ship to the fleet and other
possible landmarks appears to be of case 2. Describing the
relationship of the wagon within the barge is a somewhat murky case
though since the barge is a object of sufficient size that case 2
may be applied also.

Assuming the observer is your average human, would it be appropriate
to define a minimum-size and maximum-size thresholds for scenic
descriptives?
A thought for a general scene (that is when one first walks into a
room or area). Start a description with the closest objects within
the vision range that meet the mininum size threshold. Describe them
in relation to objects that meet case 1, above. If the larger object
in a case 1 relationship exceeds a maximum size threshold (ie. the
barge) describe it using case 2. If there is no case 1 relationship,
a case 2 description is used using the nearest and next largest
object. As objects are described from closer to farther away the the
minimum-size becomes a function of range. That way 5 people directly
in front of you would be described but a person 60 yards away would
not? Perhaps there is a maximum threshold of objects that could be
included in the description? There are only so many objects a human
will notice at once when coming upon a scene. For example, imagine
one stumbling into the Katmandu town square. There may be so many
persons, buildings objects before them that the surrounding
mountians, immense and near as they are, would not even be noticed.
