Calculate
To calculate traverse and sideshot points coordinates:
- In the Input tab:
- In From Point, enter the occupation point (the traverse point). Enter the point manually or select it from the map
or from the list
of the job points.
- Select between Azimuth/ Angle R / Angle L / Defl R / Defl L to set respectively:
- Azimuth from the known point to the calculated point. The azimuth can be entered as is, computed from the right or left angles, or deflection entered in this field and Backsight information.
- Angle to the Right is the angle at the known point from the backsight point to the calculated point in a clockwise direction.
- Angle to the Left is the angle at the known point from the backsight point to the calculated point in an counter clockwise direction.
- Deflection to the Right is the angle at the known point between the prolongation of the line from the backsight point and the line to the calculated point in a clockwise direction.
- Deflection to the Left is the angle at the known point between the prolongation of the line from the backsight point and the line to the calculated point in an counter clockwise direction.
- In HD Gnd/HD Grid (depends on the current coordinate system), set the horizontal distance offset along the azimuth line.
- In Vert Dist, set the height offset.
- In To Point, enter the name of the calculated point.
Select the code for this point from the drop-down list. Click
to set the point's attributes. More...
- Press BS Point to display the BS Point dialog that allows you to enter the Backsight Point or Backsight Azimuth. If a BS point has not been entered, then an Azimuth is required. In this case if an angle value is entered as Angle Right, Angle Left, or Deflection, this value will be considered as azimuth.
- Press Side Shot to compute the coordinates of the To Point, based on the entered values for Azimuth/Angle Right/Angle Left/Deflection, Horizontal and Vertical distances. The From Point does not change, and To Point is incremented to the next new Point in the database.
- Press Traverse to compute the coordinates of the To Point, based on the entered values for Azimuth/Angle Right/Angle Left/Deflection, Horizontal and Vertical distances. The From Point changes to the To Point, and the To Point changes to the next new name in the database.
- In the Results tab, review the results of the calculation and:
- Click
to save the calculated point and to continue calculating the traverse.
- Click
to save the data to a txt file if required.
- The Map tab shows the job's objects with the illustration for the results and supports generation of a field report with the results of calculation (use the Create Field Report command from the context menu).
- The Drawing tab shows the illustration for the results and supports generation of a field report with the results of calculation (use the Create Field Report command from the context menu).
BS Point
The BS Point dialog allows you to enter the backsight azimuth for the Traverse calculation. The azimuth can be computed from the traverse's From Point to a backsight point or can be entered manually.
Select BS Point or BS Azimuth to set the backsight point location or the backsight azimuth. The backsight point may be entered manually, selected from the map
or from the list
of the job points.
If a backsight point is entered, the Code and string of the point are displayed.
Adjust
Before the result of a traverse can be used to determine its location from
the traverse stations, the traverse must be mathematically consistent. The misclosures in the linear and angular measurements must be adjusted out. The process of applying corrections to the corresponding point coordinates is called traverse adjustment. In the current job, the coordinates of the network after adjustment will be displayed without changes. The list of adjusted coordinates for the given network will be saved in a new MAGNET Field job.
To perform an adjustment of a surveyed traverse:
- Set the data needed for the task in the first Adjustment dialog. More...
- Select the method of the traverse adjustment and calculate the task. More...
- Review the results of adjustment. More...
Adjustment Settings
Set the data needed for the task:
- In Start Point, set the station on which the traverse originates. This can be entered manually, selected from the map
or from the list
of the job points.
- In End Point, set the station on which the traverse closes.
- Enable the Adjust Elevations check box to include elevations adjustment if it is needed to determine elevations in the traverse.
- Enable the Adjust Sideshots check box to include sideshots in adjustment.
- If required to consider Earth curvature and atmospheric refraction corrections, set the value of Curvature refraction either to 0.14 or 0.20.
- In the Job to store the results, click New to create a new job to store the adjusted coordinate of the network. A full path to the job file will be shown.
- Click Next to continue. More...
Adjustment Method
To adjust the traverse:
- Select the method of traverse adjustment:
- Enable the Apply Compass Rule check box to adjust the traverse by the compass rule.
- Enable the Apply Angle Balance check box to adjust angles in the traverse. In this case the Closing Angle will be shown for the traverse adjustment.
- Click Adjust to calculate the task.
