22. INTERSECTIONS
138
2 Intersections
2 intersections are defined according to 1
st
Pt. and 2
nd
Pt. as shown below
Intersections created from Azmth 1 and H.dist 2 (or H.dist 1 and Azmth 2):
An azimuth angle has already been set for a point. The furthest point from
this point is set as Intersection Pt. 1, and the closest point set as Intersection
Pt. 2.
• Intersections created from H.dist 1 and H.dist 2:
Intersection to the right of the straight line between 1
st
point and 2
nd
point
set as Intersection Pt. 1 and the point to the left set as Intersection Pt. 2.
Precaution when performing intersection measurement
In the following cases the coordinates of intersection points cannot be
calculated.
When Azimuth 1 = Azimuth 2.
When Azimuth 1 – Azimuth 2 = ±180°.
When H.dist 1 = 0, or H.dist 2 = 0.
When the coordinates for 1
st
Pt. and 2
nd
Pt are the same.
