1. Identify potential sources of spatial data.
   • Extent, content, intended use, accuracy, precision and format of required spatial datasets are clearly identified from the specifications provided by the suppliers of spatial data.
   • A search is undertaken via a range of media to identify sources of information.
   • Metadata for potential spatial datasets is obtained to assist in determining the most appropriate spatial data source.
   • All potential sources of spatial data are listed according to organisational guidelines.
   • OHS issues are considered at all times.
   • Skills and knowledge are updated to accommodate changes in operating environment and equipment.
2. Assess spatial data availability and suitability.
   • Spatial datasets are assessed for suitability against the specifications.
   • Availability of suitable data is verified with potential suppliers.
   • Constraints on the use of spatial data are assessed against specifications.
   • Sample data is obtained and assessed to further ensure its suitability, where required.
   • Maintenance requirements are determined to ensure currency.
3. Document spatial data assessment.
   • A written assessment of data availability including cost, licensing conditions and constraints on use is completed according to organisational guidelines.
   • A written assessment of the suitability of available data, including comparison with quality, accuracy, standards and format requirements is completed according to organisational guidelines.
