Elements and Performance Criteria

1. Access spatial data.
   • Project spatial data requirements and constraints, and client requirements, are identified and documented in consultation with appropriate persons.
   • Spatial datasets are retrieved from data storage and other relevant sources and new data is captured according to project and organisational requirements.
   • Data is manipulated into appropriate format to meet project requirements.
2. Query and interpret spatial data.
   • Data is queried and interpreted using appropriate equipment and software application according to project requirements.
   • Data is verified for integrity and relevance using industry-accepted statistical tests and methods according to project requirements.
   • Irregularities are identified and resolved, and results recorded and documented according to organisational requirements.
3. Collate spatial data.
   • Spatial data is collated according to organisational requirements.
   • Most appropriate format and database for spatial data are selected according to organisational requirements.
4. Validate spatial data.
   • Tools for testing validity of information and data are identified, accessed and used according to organisational requirements.
   • Problems with collated data are identified and resolved to ensure quality and usability according to organisational requirements.
   • Spatial data is archived and records and documentation are completed according to organisational requirements.
