    Specific Outcomes and Assessment Criteria: 

    SPECIFIC OUTCOME 1 
    Demonstrate an understanding of geographical features and layers. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    A feature as an abstraction of a real or imaginary world phenomenon can be described. 
    ASSESSMENT CRITERION NOTES 
    Please note that a feature is a high-level abstract concept, to which spatial attributes (the geometry) and non-spatial attributes are attached. A feature is not just a vector object! 

    ASSESSMENT CRITERION 2 
    A layer as a collection of real or imaginary world phenomena can described. 
    ASSESSMENT CRITERION NOTES 
    Please note that a layer is a collection of geographical phenomena of the same geometric type, which for this Unit Standard are limited to the 2D primitives, point, line or polygon. 2D primitives might have height values. 

    ASSESSMENT CRITERION 3 
    The difference between using a feature and a layer for representing a real-world phenomenon can be shown. 

    SPECIFIC OUTCOME 2 
    Demonstrate an understanding of topology. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    The basic types of topology are identified and can be explained. 
    ASSESSMENT CRITERION RANGE 
    Intersection, coincidence, adjacency, containment and their inverses.
     

    ASSESSMENT CRITERION 2 
    The manner in which topology links features and geometry is explained and can be shown. 

    ASSESSMENT CRITERION 3 
    Basic topological models for geographical data are explained and can be differentiated. 
    ASSESSMENT CRITERION NOTES 
    Please note that the topological relationship of connectivity is a key insight that the candidate must have for the network model. 
    ASSESSMENT CRITERION RANGE 
    Network model, Triangulated Irregular Network (TIN)
     

    ASSESSMENT CRITERION 4 
    Some benefits of topology and its usage can be listed. 
    ASSESSMENT CRITERION RANGE 
    Including, but not limited to, data cleaning, boundary sharing, relationships between features, buffering.
     

    SPECIFIC OUTCOME 3 
    Demonstrate an understanding of feature types. 
    OUTCOME RANGE 
    Point, line, polygon. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    A feature type as a mechanism for collecting or classifying features based on their primary characteristics, is understood and can be explained. 
    ASSESSMENT CRITERION NOTES 
    Please note that a feature type is also known as a feature class. The primary characteristic is the one of most interest to the user, and hence the one they would select for defining their feature types. 

    ASSESSMENT CRITERION 2 
    The continuum between feature types and feature attributes is illustrated. 

    ASSESSMENT CRITERION 3 
    The correct feature type can be selected from a feature catalogue and/or feature classification scheme. 
    ASSESSMENT CRITERION NOTES 
    Please note that the key principle is that one person's attribute could be another's feature type - an expert in a particular field (eg: forestry) would classify a feature (eg: a tree) to a finer level (eg: to species), than would someone with only a peripheral interest in the feature. 

    ASSESSMENT CRITERION 4 
    The correct feature type is selected and assigned the appropriate attribute data where required. 

    SPECIFIC OUTCOME 4 
    Demonstrate an understanding of feature attributes. 

    ASSESSMENT CRITERIA
     

    ASSESSMENT CRITERION 1 
    A feature attribute as a characteristic of a feature is explained. 
    ASSESSMENT CRITERION RANGE 
    Attribute name, attribute definition, attribute type, attribute value domain.
     

    ASSESSMENT CRITERION 2 
    The Geometrical properties of features are explained. 
    ASSESSMENT CRITERION RANGE 
    Size, shape, dimensionality.
     


    UNIT STANDARD ACCREDITATION AND MODERATION OPTIONS 
    Moderation
  • 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.

    The following embedded knowledge is addressed in an integrated way in the unit standard:
  • Basic knowledge of geography.
  • Basic computer literacy.

  • UNIT STANDARD ASSESSOR CRITERIA 
    Assessors should keep the following principles in mind when designing and conducting assessments against this unit standard:
  • Focus the assessment activities on gathering evidence in terms of the main outcome expressed in the title to ensure assessment is integrated rather than fragmented. Remember we want to declare the person competent in terms of the title. Where assessment at title level is unmanageable, then focus assessment around each specific outcome, or groups of specific outcomes.
  • Make sure evidence is gathered across the entire range, wherever it applies. Assessment activities should be as close to the real performance as possible, and where simulations or role-plays are used, there should be supporting evidence to show the candidate is able to perform in the real situation.
  • Do not focus the assessment activities on each assessment criterion. Rather make sure the assessment activities focus on outcomes and are sufficient to enable evidence to be gathered around all the assessment criteria.
  • The assessment criteria provide the specifications against which assessment judgements should be made. In most cases, knowledge can be inferred from the quality of the performances, but in other cases, knowledge and understanding will have to be tested through questioning techniques. Where this is required, there will be assessment criteria to specify the standard required.
  • The task of the assessor is to gather sufficient evidence, of the prescribed type and quality, as specified in this unit standard, that the candidate can achieve the outcomes again and again and again. This means assessors will have to judge how many repeat performances are required before they believe the performance is reproducible.
  • All assessments should be conducted in line with the following well documented principles of assessment: appropriateness, fairness, manageability, integration into work or learning, validity, direct, authentic, sufficient, systematic, open and consistent.
