Radiations

Calculate set out radiations

The Radiations option to calculate set out radiations from a nominated station (selected either graphically or by name from a list) to a selected object. The calculations can be stored in a report file. See Appendix A for an example.

Instructions

On the Survey menu point to UG Survey and then click Radiations to display the Traverse radiations panel.

Instrument Setup tab

Station Library

Select a station library from the drop-down list.

Instrument Information

Station

Select an instrument from the drop-down list.

Height

Enter the instrument height.

Backsight Information

Station

Select the backsite station from the drop-down list.

Back bearing

Select from three choices of back bearing:

  1. Use calculated back bearing
  2. Use back bearing from station library of  [Enter source].
  3. Use alternate back bearing of  [Enter source].

Distance method

Select the distance method:

  1. Vertical Angle/slope Distance
  2. Horizontal Distance/Vertical Distance

Target height convention

Select which convention you are using:

  1. Underground (positive entered target height implies target is below the mark)
  2. Standard (positive entered target height implies target is above the mark)

Radiations tab

Layer/object naming

Enter the name (and optionally a description) of the layer in which the shots are to be stored and the name (and description) for each shot, that is, object name. The default object name is <instrument_station>. The default object description is 'Fieldbook shots from <instrument_station>.

Combine all like-featured data into one object

Select this option if you want the data to be input as a single object.  They can be split into separate objects based on how far apart the objects are.  A setting of 0 means that all data will be broken into separate objects.

Horizontal Angles

The angles can be true bearings or, more often, a direction based on the Face Left/Face right mean to the backsight for the first set of angles (taken from the Traverse panel). Directions is the default.

Report File

Select this option if you want to save the results to a report.  Enter a report name and the report will be saved to the working directory.
