Intersections

The Intersections command allows for the calculation, selected solution and storing of point data based upon standard surveying methods of:

• Bearing-Bearing - Yields one unique solution.
• Bearing-Distance - Generally yields two solutions or no solution.
• Distance-Distance - Generally yields two solutions or no solution.

• Clear: (icon) Use this button to clear data from the routine.
• First Point/Second Point: For each of the point groupings are the following controls:
  • Point ID: Indicate the point that serves as the basis of the direction/distance information to follow.

    Note: Points can also be specified through the standard Point List and/or Map Screen pick.

  • Azimuth: Indicate a known direction from the Point ID.

    Note: The current Angle setting determines how values are interpreted.

    Note: The current Angle Entry & Display setting dictates whether angles are prompted as Azimuth or Bearings.

    Note: Bearings can be entered in three forms:

    • SE40.5945 becomes S40°59'45"E
    • S40.5945E becomes S40°59'45"E
    • 240.5945 becomes S40°59'45"E

    The direction can also be specified through the Use Points button.

    More Information

    

    • From Point: Indicate the point that determines the starting point of the direction.
    • To Point: Indicate the point that determines the ending point of the direction.

    Note: Points can also be specified through the standard Point List and/or Map Screen pick.

  • Distance: Indicate a known distance from the Point ID.
  • Off: Use these edit controls to create intersections that are:
    • defined by parallel offsets to the defined or computed direction (positive values for right, negative values for left), and/or,
    • an additional amount that is added to a cited distance.

Note: The Enter key moves forward through the edit boxes.

Upon pressing ✅, a Map Screen displays the solution(s) with the option to review and/or store the desired point(s).

Main Measurement

The calculated point(s) will appear on the screen with the input data detailed at the bottom of the screen.

Note: If a solution cannot be determined based on the supplied information, a No Valid Solution! alert is displayed.

Within Intersect are these measurement/configuration tools:

Intersect Measurement/Configuration Buttons

Legacy Icon	Graphic Icon	Action
		Store: Stores the picked solution as a point at which point it inherits the specified point number, description, and the elevation displayed at the bottom of the screen. Note: This action creates SP records (identical to the results of Keyboard Input) in the Raw File, storing the calculated coordinates for each new point.
		Modify: Permits the customization of the desired Intersection values.
		Results: Displays a text-based summary of the solution(s). More Information Save: (icon) Launches the standard File Selector that saves a report of the inverse to a *.TXT file.

Note: Also within Intersect are other common controls; most notably the various Map Screen View Controls.

Intersection Examples

Consider the figure below containing a 3-4-5 right triangle where the coordinates of P2 and P3 are known and we want to establish the location of P1:

Bearing-Bearing

This method locates a point at the intersection of two vector directions.

Bearing-Distance

This method locates a point at the intersection of a vector direction from one point and a horizontal distance from the other point.

Distance-Distance

This method locates a point at the intersection of horizontal distances from the two points.
