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 GIS occupational area and is intended for persons who aim to achieve career advancement by gaining GIS skills leading to a qualification based on unit standards. A person who has successfully completed this unit standard will have a basic understanding of photogrammetry, aerial surveys and associated problems and advantages.

A person credited with this unit standard is able to:
  • Demonstrate a basic understanding of aerial photography.
  • Demonstrate a basic knowledge and understanding of Ground Control.
  • Demonstrate an understanding of the science of photogrammetry. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
    The credit calculation is based on the assumption that learners are already competent in terms of the following:
  • Communication at NQF Level 5.
  • Mathematical Literacy at NQF Level 5. 
    		•

    UNIT STANDARD RANGE 
    The following scope and context applies to the whole unit standard:
  • Including but limited to: Basic geometric characteristics of Aerial photographs, Photographic scale, Ground Control and mapping from aerial photographs.

    Specific range statements are provided in the body of the unit standard where they apply to particular specific outcomes or assessment criteria.

    Range statements are included with specific outcomes as necessary. 
    		•

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Demonstrate a basic understanding of aerial photography. 

    ASSESSMENT CRITERIA

    SPECIFIC OUTCOME 2 
    Demonstrate a basic knowledge and understanding of Ground Control. 

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    The use of ground control points is understood and explained in terms of photogramentry. 

    ASSESSMENT CRITERION 2 
    Surveyed ground control points are identified on an aerial photo. 
    ASSESSMENT CRITERION RANGE 
    Specific points as described by the surveyor.
     

    SPECIFIC OUTCOME 3 
    Demonstrate an understanding of the science of photogrammetry. 

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    Limitations of raw aerial photographs are understood and explained in terms of photogramentry. 
    ASSESSMENT CRITERION RANGE 
    Distortion, tilt.
     

    ASSESSMENT CRITERION 2 
    Principles of stereometric image formation are understood and explained in terms of photogramentry. 

    ASSESSMENT CRITERION 3 
    The use of digital elevation models in relation to photo rectification is understood and explained in terms of photogramentry. 

    ASSESSMENT CRITERION 4 
    Characteristics of Ortho photos are understood and explained in the context of photogramentry. 


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
  • Anyone assessing a learner against this unit standard must be registered as an assessor with the relevant ETQA.
  • Any institution offering learning that will enable achievement of this unit standard must be accredited as a provider through the relevant ETQA by SAQA.
  • Moderation of assessment will be overseen by the relevant ETQA according to the moderation guidelines and the agreed ETQA procedures. 
    		•

    UNIT STANDARD ESSENTIAL EMBEDDED KNOWLEDGE 
    Essential embedded knowledge will be assessed through assessment of the specific outcomes in terms of the stipulated assessment criteria. Candidates are unlikely to achieve all the specific outcomes, to the standards described in the assessment criteria, without knowledge of the listed embedded knowledge. This means that for the most part, the possession or lack of the knowledge can be directly inferred from the quality of the candidate's performance. Where direct assessment of knowledge is required, assessment criteria have been included in the body of the 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.
