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 will enable qualifying learners to apply image analysis methodology in different contexts. Learners will be able to interpret requests from clients, work out a plan of action to determine information and provide deductions made to the client in various formats. This unit standard will enable learners to use image interpretation methods and techniques to make findings for various purposes.

Qualifying learners will be able to:
  • Evaluate features of the subject of analysis.
  • Apply principles of image interpretation (II).
  • Apply an image interpretation process.
  • Make deductions and apply quality assurance to verify user requirements. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
  • Communication, at NQF Level 4.
  • Mathematics, at NQF Level 4.

    The learners is presumed to be competent in the following unit standards:
  • Perform scaling and mensuration of vertical and oblique aerial images, Level 5.
  • Design a quality assurance system, Level 5. 
    		•

    Process may refer to but is not limited to:
  • Plans, structure of work and format of the product and output.
     
    		•

    ASSESSMENT CRITERION 3 
    A search method is applied in a given situation to detect objects and features. 
    ASSESSMENT CRITERION NOTES 
    Both methods must be assessed. 
    ASSESSMENT CRITERION RANGE 
    Search methods refer to the general method and the study method.
     

    ASSESSMENT CRITERION 4 
    Search methods are analysed according to their advantages, disadvantages and limitations in given situations. 

    ASSESSMENT CRITERION 5 
    A given situation is assessed in order to select which search method should be used. 

    ASSESSMENT CRITERION 6 
    The identity of detected objects are verified using measurement techniques. 

    ASSESSMENT CRITERION 7 
    The terms "possible" and "probable" are distinguished for use. 

    SPECIFIC OUTCOME 4 
    Make deductions and apply quality assurance to verify user requirements. 

    ASSESSMENT CRITERIA     

    ASSESSMENT CRITERION 1 
    Findings are verified using technical references. 
    ASSESSMENT CRITERION RANGE 
    Technical references refers to but is not limited to calculations, measurement and equipment specifications.
     

    ASSESSMENT CRITERION 2 
    Findings are assessed to determine whether it meets the original request from clients. 

    ASSESSMENT CRITERION 3 
    Task specific information is compared with historical information. 
    ASSESSMENT CRITERION RANGE 
    Historical information also refers to archived information where applicable.
     

    ASSESSMENT CRITERION 4 
    Comparisons made are evaluated in order to make deductions on significant findings.

    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.
