Two Line Intersection

The two line intersection command is used to locate the corner of an object, whose corner cannot be directly measured. Two intersecting lines will be defined by four measurements, two shots on each line. The intersection of these two lines will define the corner of the object. This routine is intended to be used with a reflectorless total station.

Measure Points

When you start the two line intersection command, you will see an empty list. Each row represents a measurement to a point on one of the two lines needed to compute the intersection.

Highlight the row that you would like to make a measurement for and simply press the Measure button to begin the measuring process.

If you need to redo a measurement, simply highlight it in the list and press the measure button.

Notes:

1. You can shoot the points in any order you like, FieldGenius will determine what direction to go in to compute an intersection

2. The northing and easting values for the new point will be computed using the intersection of the two lines.

3. The two lines you define will rarely intersect at exactly the same point. The elevation of where the lines intersect will be averaged, and used as the z value for the new point.

Note: You can increase the size of the text shown in the grid by setting the Text Size option in the Options screen.

Store the Point

Once you've made measurements to the four points that will define the two intersection lines, you can press the Store Point button. This will store a point in the map screen, store a point in the database as well as record information to the raw file.

Raw File

Everything about the intersection is stored in the raw file.
