PURPOSE OF THE UNIT STANDARD

This unit standard has been developed for the surveying occupational area and is intended for persons who aim to achieve career advancement within social and economic transformation by gaining Geographical Information System (GIS) skills for use in a surveying environment leading to a qualification based on unit standards. A person who has successfully completed this unit standard is able to select a data structure for a Geographical Information System and illustrate a clear understanding of the differences between a vector and raster data structure.

A qualifying learner credited with this unit standard will be able to select a vector or raster data structure or combine the two data structures in a Geographical Information System (GIS) and is able to:

Display knowledge related to database structures.

Display knowledge of raster data structures.

Display knowledge of vector data structures.

Select a data structure for a geographical information system (GIS).

LEARNING ASSUMED TO BE IN PLACE AND RECOGNITION OF PRIOR LEARNING

NQF level 4 numeracy and literacy and the ability to operate a standard desktop GIS application will facilitate better understanding and proficiency in this 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.
