Correction of magnetic declination by repeated positioning using trees

The value of magnetic declination is changing in time. Field-Map enables you to calculate the correction of the magnetic declination when positioning using trees. Correction of the magnetic declination is calculated for two or more trees.


Note:

It’s important to judge if is necessary to correct the magnetic declination at all as the deviation can have several causes (for example the reflector position during previous measurement).
