To address the question of optimized maps for aviation use, if that indeed
is relevant to this discussion, he should go to an outlet that sells
aviation maps and ask for a GPS-optimized map. I think that he will be
surprised.

My post to that group requesting advice and comment was way too long; I
imagine it made for quite tedious reading, which I don't think helped
my case as much as it might have done.

But I'm happy with the replies (in that group and certainly here),
overall :-)

My opponent, even though he evidently knows next-to-nothing about the
GPS, or GPS survey, is trying to discredit a set of GPS coordinates
that has cost me time, energy and lots of money to obtain (obtained
with diligence and after a sufficient number of hours of research (in
my opinion)). And he thinks I should use theodolites and trig points
instead of GPS.


Thanks to all that have replied.
