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 occupational area and is intended for persons who aim to achieve career advancement by gaining surveying skills leading to a qualification based on unit standards. A person who has successfully completed this unit standard is able to apply basic photogrammetric compilation principles for map production.

A person credited with this unit standard is able to:
  • Demonstrate knowledge related to the preparatory tasks for photogrammetric compilation
  • Demonstrate knowledge related to the compilation of spot heights and contours
  • Demonstrate knowledge associated with the compilation of detail
  • Demonstrate knowledge related to edge matching when compiling a map or model.
  • Compile a thematic plan or map using a manual or digital process. 

  • LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    NQF level 4, and numeracy and literacy that will facilitate better understanding and proficiency in this unit standard. The ability to interpret photographic detail from aerial photography for annotation purposes and obtain information from a plan will facilitate better understanding and proficiency in this unit standard.

  • REREGISTRATION HISTORY 
    As per the SAQA Board decision/s at that time, this unit standard was Reregistered in 2012; 2015. 

    UNIT STANDARD NOTES 
    Supplementary Information:

    The relevant information is contained in one or more of the following documents:
  • Training manuals
  • Survey Codes of Practice
  • Survey Instructions
  • Managerial Instructions
  • Professional Publications

    Manual - detail compilation can be demonstrated on a hardcopy of an orthophoto map or rectified photograph, should no software be available for the learner to show digital compilation. The essence of the outcome is for the learner to be able to demonstrate an understanding and ability of doing compilation, irrespective of the medium used for the compilation.

    This information shows the current accreditations (i.e. those not past their accreditation end dates), and is the most complete record available to SAQA as of today. Some Primary or Delegated Quality Assurance Functionaries have a lag in their recording systems for provider accreditation, in turn leading to a lag in notifying SAQA of all the providers that they have accredited to offer qualifications and unit standards, as well as any extensions to accreditation end dates. The relevant Primary or Delegated Quality Assurance Functionary should be notified if a record appears to be missing from here.
