Elements and Performance Criteria

1. Confirm reliability of spatial data.
   • Task requirements are clarified with appropriate persons.
   • Equipment is selected, set up and checked to ensure correct operation and functionality.
   • Spatial data updates are accessed and checked to confirm currency and relevance, and recorded in consultation with appropriate persons.
   • Spatial data is checked and edited to ensure it is compatible and in acceptable format according to task specifications.
   • Entities and attributes are used to display spatial information while maintaining integrity and consistency of data.
2. Edit and update spatial data.
   • Spatial data is amended and replaced to meet task requirements in consultation with appropriate persons.
   • Existing and new data is edited, prepared and integrated according to task requirements.
   • Spatial datasets are tested and validated to ensure integrity and quality according to task requirements.
   • Documentation is amended and updated according to organisational requirements.
3. Carry out data backup and recovery.
   • Data backups are implemented to ensure data is accessible in contingency situations according to organisational requirements.
   • Backup system is tested to ensure that data can be retrieved, and problems are resolved in consultation with appropriate persons.
4. Archive data.
   • Spatial dataset to be archived is checked for completeness and manipulated where necessary, in consultation with appropriate persons.
   • Metadata is created according to organisational requirements.
   • Archived spatial data is stored in a secure location, and details are recorded according to organisational requirements.
