Data quality assurance

Data quality model

The Atlas of Living Australia (Atlas) has developed a data quality model to ensure the high quality of the data in the Atlas.

Download information on the model:

Data quality checks

When data is uploaded into the Atlas:

  • georeferences are checked, ie ensure that the latitude and longitude have not been transposed etc
  • the current species name is determined and allocated to the record
  • completeness of the records.

Results of these checks are published in the Atlas and full details of any changes made are viewed by clicking on the ‘Original vs Processed’ button on the occurrence record page; see next image.

Data sandbox

A sandbox environment is available for users to upload their data, run it through the data quality tests and sensitivity checks and then visualise the data on a map. Results of the data quality tests can be used to modify data ‘at source’ or simply be used to highlight quality issues in the uploaded data.
