Implications and caveats

Severity: Warning

If the geodetic datum is missing or unreadable, but coordinates are supplied, the ALA will assume the geodetic datum is WGS84.

This may mean occurrence records are not plotted accurately on the map at larger scales. Providing the geodetic datum will ensure the occurrence record is as accurate as possible and can be used for a wider range of uses.

Data custodian recommendations

Review geodetic information and supply if possible. Review location of occurrence and where coordinates would position the occurrence using different geodetic datum information.
