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 within social and economic transformation by gaining surveying skills leading to a qualification based on unit standards. A person who has successfully completed this unit standard is able to reduce basic distance measurements (tape or Electronic Distance Measurement (EDM)) for use in Surveying.

A qualifying learner credited with this unit standard will be able to:
  • Demonstrate basic knowledge related to instruments used for distance measurement in surveying.
  • Demonstrate a basic understanding of the theory and principles associated with distance measurement for the use in surveying.
  • Demonstrate a basic understanding of the principles associated with distance reduction to survey datum.
  • Reduce basic distance measurements in accordance with survey standards. 

  • 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.

    PROVIDERS CURRENTLY ACCREDITED TO OFFER THIS UNIT STANDARD: 
    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.
