jan
i wish someone would straighten this out
as there now seems to be a multiple confusion here
to begin with
you are apparently still considering these 7digit numbers as utm
but having tried them out
i believe karolis must be right
that they would have to be something else
in any case you may be using different standards
as well as different levels of accuracy
tho i could be mistaken
for i confess i am completely baffled by now anyway
also it may just be the fault of my old computer
but this map looks blurry & scarcely readable from here
