Tie-line method for collecting correction data
Note: If you need more than one day to complete your survey in the Line-type
mode, please make sure that you collect all your Tie-points as the first
data that you store in memory, i.e. before you survey any lines. This
ensures that they will not be erased when clearing memory to make
room for the next day’s data.
