Abstract
The data quality efforts within the Atlas of Living Australia are focussed on the design and implementation of a suite of data quality checks and metrics aimed at improving overall data quality standards of occurrence data by flagging occurrence records which may have particular issues and alerting custodian and users of the data to those issues.
Emphasis is being placed on the detection of potential spatial outliers using environmental outlier detection and validation against expert distributions. Duplicate detection algorithms highlight potential duplicate records and annotation tools allow crowd sourced record comments to be fed back to record owners.
