In all of the tables in this document, both the pre-2009 NQF Level and the NQF Level is shown. In the text (purpose statements, qualification rules, etc), any references to NQF Levels are to the pre-2009 levels unless specifically stated otherwise.  

This unit standard does not replace any other unit standard and is not replaced by any other unit standard. 

PURPOSE OF THE UNIT STANDARD 
This unit standard has been developed for the surveying occupa-tional area and is intended for persons who aim to achieve ca-reer advancement by gaining surveying skills leading to a qualifi-cation based on unit standards. A person who has successfully completed this unit standard is able to operate an analytical comparator and measure data for Aerial Triangulation purposes.

A person credited with this unit standard is able to:
  • Prepare an analytical stereo instrument for use
  • Observe and record Fiducial marks
  • Observe and record Control and Tie points 
    		•
