Survey Instrument Settings

From this dialog box, you may alter your standard instrument settings. These settings may be accessed by selecting the Observations option from the Settings menu. Or from the Instrument button in the reduction dialog box.

• Units (Unless this is overridden by settings within the file itself.)  

  • Reading Type: Sets the format of the angles found in an imported file containing raw survey observations. Three options are available HaVaSd (Horizontal angle, Vertical angle and Slope distance) or, HaHdVd (Horizontal angle, Horizontal distance and Vertical distance), or HaHdGd (Horizontal angle, Horizontal distance, Ground difference). By default, the format is set to HaVaSd.
  • Angles:  Sets the Units of the angles found in an imported file containing raw survey observations. Three options are available DD.MMSS (Degrees Minutes Seconds), Decimal degrees or Gons (Grads). By default, this format is set to DD.MMSS.
  • Distances: Sets the Units of distances found in an imported file containing raw survey observations (Metric and Imperial units)
     

• Corrections

  • Vertical Circle: Applies this offset to all angles imported from a file. Enter a value in seconds to correct the vertical circle readings if the instrument is known to be out of adjustment.
  • EDM Distance: Applies this offset to all EDM measured distances within a file. If the prism you are using with an EDM is incompatible with the instrument, or if you find that the wrong prism constant was entered during the survey, use this field to make the appropriate adjustments.
  • Maximum Pogo: Sets the value above which any pogo/tgt height readings are considered 2d and given a null height on reduction.
    
    

• Vertical Circle

  • Defines how vertically up to positive horizontal in a clockwise direction are configured. Selects the vertical circle azimuth, by default, this is set at 0 > 90, i.e. 90 represents true horizontal and 0 the azimuth.

• Horizontal Circle

  • Defines the direction horizontal angles increase in. Select the direction in which to measure +ve angles. By default, this is set to clockwise.
    
    

• Flags

  • Alphanumeric Numbers: If this option is enabled, for nonstandard survey instrument files (.log) when a character is found in a points number field (point id on Leica) that is NOT a number e.g. STN1. Then it is assumed to be a control reading and the whole Number is used as the name of the Station being observed.

  • Slope Hz Offset Dimension: If this option is enabled, Hz Offsets are offset along the slope measured from a total station, rather than being added planar along the line of sight after the point has been initially calculated. In essence, it can act like a large prism constant when enabled.

  • Import GPS Statistics: If this option is enabled then Quality, Antenna Ht, DOP, and other attributes are added to GNSS readings if they are present in the source file containing the survey data.

  • Import GPS satellite info: This option Imports any extra satellite information stored within the raw data. 
  • Import GPS precision info: This option Imports any extra precision information stored within the raw data.

  • Leica FreeCode After Point: If this option is enabled then n4ce will apply Leica "Free Codes", after the point has been stored. 

  • Use prism Type= not PC=: Changes the Prim constant from PC to Type.
  • XML Import Code Over Name: If the option is checked then the code field defines the station name rather than the name field within the LandXML file.
  • Ignore Logger Comments: Tells n4ce to ignore some common logger comments that can add unnecessary remarks to each point. Such as the identifier "Modified" on some Trimble formats.
  • Curves CCCC to TCCT: Allows the users to not have to set a ,T (Tangent) at the beginning and end of curves that start and finish tangentially. This option tells n4ce to assume the first and last C's are in fact Tangents instead. 
    
    

• XPad RAW Files

  • Import Descriptions: Determines whether n4ce should bother reading the Description of the Code as a Remark.
  • Ignore Curves: This function tells n4ce to ignore any Curving added by tools on the logger and use n4ce comma codes instead. This allows for n4ce's comma codes such as TS and TE for Tangent Start and Tangent End to work.
    
    

• Trimble JXL Files

  • Read Raw Observations: When doing offsets to a point using LROffset, IOOffset or DUOffset, JXL stores both the raw readings and adjusted readings. If Read Raw is set, it will read in the raw observation together with the appropriate L, H or V values.  If not, just the adjusted observation so if a mistake is entered in the field, you can't update it.
