Manual Traverse

This command allows for manual entry of angles and distance and calculates sideshots or traverses from a known occupied point and is one of three methods for performing this work. Other methods are:

• Manual Total Station: Set the equipment type to Manual Total Station and enter the traverse and sideshot data within the Store Points command.
• Map Screen: Use the Command (Cmd:) line in the Map Screen and use keyboard-entry of data.

All three of the methods allow for zenith angle prompting as an option and will store data to the Raw File for re-processing and will allow entry of instrument heights and target heights.

• Map View: (icon) To the immediate left of the Orange Back Arrow is Map Screen Preview button that allows you to see the location of the calculated point, in reference to the Occupied Point and Backsight Point.
  More Information

  

• Occupy Pt ID: Indicate an existing point from where calculations begin.

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

• Backsight Pt ID: Specify an existing point that serves as an orientation direction for turned angle/deflections.

  Note: If the Horizontal Angle direction is defined by a Bearing or Azimuth, a backsight point is not required.

• Target Pt ID: Indicate the point ID that will be calculated based on the information to follow.
• Desc: Specify a description or Field Code for the point being computed.
• El/Off: When enabled, a "check screen" is activated that allows you to set a specific Elevation and/or Offset from the traverse leg (positive for right and negative for left).
  More Information

  

• TR Mode: When enabled, Traverse Mode will cause the routine to "traverse up" to the target point number, so that the new occupied point number will automatically change to the last target point number, and the new backsight will change to the last occupied point. Otherwise, Sideshot mode is assumed.

  Note: You can always manually change the fields for Occupied Point and Backsight Point to "force" a traverse movement.

• Horizontal Angle: Indicate the horizontal angle type and value.
  • NE: North East bearing
  • SE: South East bearing
  • SW: South West bearing
  • NW: North West bearing
  • AZ: North-based Azimuth
  • SAZ: South-based Azimuth
  • AL: Turned Angle Left
  • AR: Turned Angle Right
  • DL: Turned Deflection Angle Left
  • DR: Turned Deflection Angle Right

  Note: You can also enter point-defined directions (e.g. 6,7 for the direction from 6 to 7, or 6,7+90 for 90° to the right of the direction of 6 to 7).

• Vertical Method: Indicate the method and value by which the elevation aspect of the point is determined.
  • Z: Known Elevation
  • SR: Slope by Ratio
  • SP: Slope by Percentage
  • DZ: Delta (change in) Elevation
  • VA: Vertical Angle
  • ZE: Zenith Angle

  Note: To get the slope from point 6 to point 7, switch to the desired Slope/Angle method and enter 6,7 for the value.

• Distance Method: Indicate the distance method and value:
  • HD: Horizontal Distance
  • SD: Slope Distance
  • SDNE: Slope Distance, No Elevation
  • HDNE: Horizontal Distance, No Elevation

  Note: Both Slope Distance methods will prompt for Vertical Angle/Zenith Angle, etc, but Slope Distance, No Elevation will calculate a zero-elevation for the Target Point Number and will reduce the slope distance by the effect of the vertical angle/zenith angle.

  Note: You can also enter the distance in the form of 6,7 for the distance from 6 to 7, or as 6,7/2 as half the distance from 6 to 7.

• Calculate: Initiates the calculations based on the current information.
• Store: Displays the Elevation/Offset confirmation dialog box (if enabled) and stores the calculated point into the job.

Note: If you wanted to interpolate a point (i.e. point 8) midway between 6 and 7, you can use all three edit boxes to accomplish this:

1. The horizontal direction would be entered as 6,7.
2. The slope would be entered as 6,7.
3. the distance would be entered as 6,7/2.

During data entry, the program displays the current mode as an extra confirmation at the bottom of the screen. Alternate methods can be quickly switched to by indicating the Capitalized letter associated with each method.
