Australia has recently moved towards a new datum, the Geocentric Datum of Australia 2020 (GDA2020), to facilitate a more robust, accurate and capable datum that is more closely aligned with the expectations of a modern, connected Australia.
The introduction of a new datum impacts all areas of the software. Esri support for GDA2020 was progressively added as the datum parameters and associated transformation methods were released. Versions of ArcGIS Pro 2.2 and greater now support GDA2020, the associated projections, and transformations between it and GDA94.
ArcGIS users who are required to continue working with data in GDA94 format may encounter problems sharing web maps from ArcGIS Pro 2.8.3 and earlier to ArcGIS Enterprise up to and including version 10.9.0.
Attempts to share a web map fail with this message – ERROR 001369: Failed to create the service
Log context messages contain the following information –
- ArcGIS Pro – “Default Map name is: Incompatible Map.”
- ArcMap – “Default Map name is: Layers.”
ArcGIS Pro 2.8.0 introduced a new set of transformations for transforming between GDA94 and WGS84
When a new map is created in ArcGIS Pro 2.8.0 and above with at least one layer in GDA94 based coordinate system, the default transformation is set to “GDA 1994 to WGS 1984 2″ as below.
This new transformation – “GDA 1994 to WGS 1984 2″ – is only available with ArcGIS Enterprise 10.9.1 and greater.
The workaround is to change the map’s coordinate transformation settings by opening map properties and changing the transformation to “GDA 1994 to WGS 1984”.
