because the ibs gives a pair of tripoint coords down
to tenths of a second or roughly 3 meter accuracy in
this rare case
only one of which oddly enough is qualified as
approximate
while the other isnt
i am not entirely sure we really do have 3 meter
accuracy here

but assuming this was a clerical oversight rather than
a silly fact
as i do
& assuming the google earth geocoord registration is
accurate down to the first of its 2 decimal places of
degminsec anyway
or again roughly 3 meter accuracy
which i am almost but not quite willing to do at this
point
it seems it may yet become worth the extra effort for
us to place the pushpin a hair more carefully & or at
a slightly tighter zoom level
because it is looking about 10 meters northeast of
where the ibs suggests it should be

not worth a satpic & tripoint stretching attachment to
be sure
because this alternative guess still falls within the
pushpin target square
but it is clearly off center & therefore off point to
that slight degree


still
this fairly begs the question
at what point does the degree of precision cease to
matter in pinning the tripoint to the satpic
especially in cases like this where we do expect
direct monumentation on site

& oddly enough too
this question will be definitively answered at our
next stop
where accuracy down to the exact inch will be at least
purported


nor will i spoil your fun by telling you the names of
the 3 countries involved in this case nor the 3 at the
next tripoint
but will just assume you can remember the 2 that are
repeated verbatim here from the previous stop
& can then guess or recollect the third one from other
past experience or from your mental map

& similarly at the next stop
etc etc




but just in case you do give up
you can still peek here in the answer drawer
