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 is useful for people who aim to achieve career advancement in the GIS field by assessing the fitness for use of data to be used for a specific project or specified applications, having been given the assessment methodology and the area and theme of interest to be checked.

A person credited with this unit standard is able to:
  • Understand the parameters given for doing the assessment.
  • Demonstrate meticulousness, conscientiousness and thoroughness.
  • Demonstrate an ability to check data manually, semi-automatically and fully automatically.
  • Log, report on the results, and determine whether or not the data are fit to use.

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

  • 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.
  • Understanding capabilities of Geo Information Systems.
  • Interpret geo-information.
  • Understand the principles of sampling, etc (from Statistics' USs).
  • Understand data quality and metadata. 

  • UNIT STANDARD RANGE 
    Range statements are included with specific outcomes as necessary. 

    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Understand the parameters given for doing the assessment. 
    OUTCOME RANGE 
    Sample to be checked, what to check against, what to check, etc. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Data for checking can be identified, extracted and prepared for assessment according to the sampling criteria provided. 

    ASSESSMENT CRITERION 2 
    Data from a source of higher authority can be identified, extracted and prepared for assessment. 

    ASSESSMENT CRITERION 3 
    Knowledge of the use to which the data set will be applied is understood and demonstrated in terms of its implications for assessing the data. 

    SPECIFIC OUTCOME 2 
    Demonstrate meticulousness, conscientiousness and thoroughness. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Meticulousness is understood and demonstrated.

    SPECIFIC OUTCOME 3 
    Demonstrate an ability to check data manually, semi-automatically and fully automatically. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Manual methods of checking are understood and demonstrated in terms of spatial data. 
    ASSESSMENT CRITERION RANGE 
    Including, but not limited to, side-by-side, overlays, written descriptions.
     

    ASSESSMENT CRITERION 2 
    Semi-automatic methods of checking are understood and demonstrated to assess fitness for use of spatial data. 
    ASSESSMENT CRITERION RANGE 
    Including, but not limited to, heads-up checking, counts, summaries.
     

    ASSESSMENT CRITERION 3 
    Fully automatic methods of checking are understood and demonstrated to assess fitness for use of spatial data. 
    ASSESSMENT CRITERION RANGE 
    Including, but not limited to, polygon closure, feature labelling, slivers, gaps, containment in polygon hierarchies, intersections, network connectivity, undershoots, overshoots.
     

    SPECIFIC OUTCOME 4 
    Log, report on the results, and determine whether or not the data are fit to use. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    Logging on the fly of checks done and errors or inconsistencies detected is understood and demonstrated. 

    ASSESSMENT CRITERION 2 
    Documenting logs legibly, intelligibly and accurately is understood and demonstrated. 

    ASSESSMENT CRITERION 3 
    Summarising logs into a report is understood and demonstrated. 

    ASSESSMENT CRITERION 4 
    The fitness for use of data is determined, understood and demonstrated by means of an assessment report. 


    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.
