:• 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
