1. A surveying pole system comprising:
a surveying pole including:
at least two telescopic sections configured for providing a length adjustability of the surveying pole,
at a first end of the surveying pole, a pointing tip suitable for being positioned on a target point of the environment,
at a second end of the surveying pole, a length reference point,
a locking mechanism configured for
locking the length adjustability in respective lock-in positions, wherein each of the lock-in positions provides a corresponding distance between the pointing tip and the length reference point, and
unlocking the length adjustability,
coded identifiers, wherein each of the coded identifiers
has a predetermined code and
is associated with one of the lock-in positions,
a coded-identifier reader configured for, in each of the lock-in positions, reading the code of a respective coded identifier associated with the respective lock-in position,
a communication device configured for transmitting a signal to a surveying instrument or to a surveying instrument controller, wherein the signal is based at least on the read code.
