Search : • Difference in length/abscissa (L)
• Lateral deviation/ordinate (Q)
• Base point coordinates (Y, X)
Given : • Baseline Start Point 1 (Y, X),
• Baseline End Point 2 (Y, X),
• lateral point 3 (Y, X)
Station coordinates and orientation need to have been
set correctly before the coordinates of point 1resp. 2
and/or point 3 can be determined by measurement.
Explanation of the polarity rule of L and Q
During entering, the polarity is based on the straight
line 1 -> 2.
+ Q Parallel displacement to the right
- Q Parallel displacement to the left
+ L Displacement from basis point 1 in the direction
of basis point 2
- L Displacement from basis point 1 in the opposite
direction to basis point 2
