exact czplsk

evidently this is or repeats the 1995 tripoint
demarcation text
http://www.volny.cz/obec.hrcava/trojmezi.html
of which the following is a partial but essential
translation
http://groups.yahoo.com/group/BoundaryPoint/message/13782
so 
i am mistaken in recalling any triple equidistance was
involved
oops
but 
am evidently correct in recalling exact measurement
from the obelisks is indeed the whole point & name of
the game here
regardless of the linden sapling & or stream
trijunction

also at the time of that discussion i added the
following thought
> given the difficulty of exact measurement on steep
terrain 
> my guess is we can already find the truest available
czplsk 
> by just eyeballing along the perpendicular pyramid
edges at the 
> apexes of the cz & pl obelisks
> so as to determine the intersection of the
projections of these 
> respective sight lines 
> somewhere down in the hollow
> whatever the horizontal & or vertical distances may
prove to be
> 
> it is just a question of whether the obelisks were
actually 
> intended & erected with enough care to be used in
this way

this shortcut should get us at least very close to the
exact truth tho
