MISSING_GEOREFERENCE_DATE - AtlasOfLivingAustralia/ala-dataquality Wiki
No date has been supplied for when the occurrence was georeferenced.
Implications and caveats
The georeference date is used as an indication of the accuracy of coordinates provided, with the earlier the date the more likely there may be some error. Earlier dates (or a georeference date that differs from the occurrence date) indicate georeferencing was more likely to be done manually based on map readings rather than using spatial positioning tools.
Data custodian recommendations
If a georeference date is available in the data, please provide it.
