Comment (by davidhassell):
Hello,
It would be great if any interested parties could review Tim's latest
changes on this ticket. In particular the many conformance requirements.
I have a minor suggestion:
In paragraph 2, a polygon has that '''it should be assumed that the first
and last node are connected. Note that CF does not require the first and
last node to be identical but allows them to be coincident if desired'''.
However, in table 7.1 it says '''a polygon is <snip> a closed line (i.e.,
the first point in the line is coincident with the last point)'''.
Also the conformance recommends (not insists) that '''the coordinates of
the first and last node in a given ring of a polygon geometry should be
coincident'''.
This is a bit confusing to me. I think that table 7.1 should be made
consistent with paragraph 2, and the recommendation should be removed.
All the best,
David
