doesn't make a problem with my method as i'm looking for the markers
"in the wild" ..
Ex. on the map i see that the border is somewhere on/near a way ...
now i take that way, find the stone(s) and set a waypint and so one

This seems a "Falk Special"
(Like not printing publishing dates, just editions anywhere :-((()
Do you know if they always use that "Hyperboloid Projektion" for
recent street maps?

I have
- Berlin - Hyperboloid 1:25000-1:35000
- München - Hyperboloid 1:22000-1:33000
but an old from Darmstadt from about 1992 (when i moved here) thats
just 1:23000

all others (VV, Eurocity, ADAC and also Falk for the Stadtatlas)
use one scale per map

i don't think it's a copyright problem, if i use the map to find the
"real thing" and record that
