Intersection
The Intersection screen computes and optionally stores the
coordinates for the intersection of two lines that are tangent to
existing points.
Each line is independently defined by a known direction
or a known length. In the situation where there is more
than one possible solution, each solution is provided and
optionally stored.
1. From the Main Menu, select . Cogo , Intersection .
2. In the Point 1 field, enter the point name that is
tangent to the first line that intersects with the other
line.
3. Toggle the first button to Distance or Azm or Brg ,
depending on if the first line intersects at a known
distance from Point 1, or at a known direction from
Point 1, respectively.
4. In the same way that you defined the first line,
define the second line tangent to Point 2 in the Second Point
section of the screen.
5. If you want to store the intersecting point(s) that are
computed from the routine, check the Store Points
checkbox and specify a point name in the same field.
If there is more than one solution, the additional
points will be stored with the next sequential point
name.
6. Tap Solve to compute the intersecting points. You
can view the point’s coordinates by tapping the
Results tab and see a graphical representation of the
intersections by tapping the Map tab.
The map shown here illustrates a situation where two
intersections were computed from a line with a known
length tangent to Point 1 and a line with a known
direction tangent to Point 2.
