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 will enable learners to understand digital imagery data in order to manipulate and analyse these images for a variety of purposes. Learners will also understand the importance of metadata and how it aligns with the image data.

People credited with this unit standard are able to:
  • Demonstrate knowledge of data structures used for satellite imagery.
  • Apply metadata for analysis purposes.
  • Describe fundamentals of digital processing. 
    		•

    LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING 
  • Mathematics at NQF Level 4.
  • Apply map and related spatial information skill for decision making in the workplace at NQF Level 4.
  • Apply image analysis methodology at NQF Level 5. 
    		•

    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.
