@GordonSumerling  The Esri Tech blog on GDA2020 https://esriaustraliatechblog.wordpress.com/2018/12/24/understanding-gda2020-and-its-relationship-with-web-gis/ recommends> Transform all data to GDA2020 and republish to Web GIS in GDA2020 or a GDA2020-based projected coordinate system. When publishing to WGS84, utilise the projection path GDA2020⇒GDA94⇒ Data will be published with GDA94 accuracy and coordinate transformations between WGS84 and GDA94 can be Performed. Create your own basemaps (Imagery, Street and Topographic) in GDA2020 DO NOT mix data from GDA94 and GDA2020 in Web GIS as there will be a 1.8 metre alignment error regardless If coordinate conversion is required in Web GIS from WGS84 to GDA2020 then a transformation path of WGS84⇒GDA94⇒GDA2020 should be utilised On point 3. Create your own basemaps in GDA2020 - has anybody done this and also successfully published as a WMTS? Is this even possible as default cache method is WGS84? Is this recommendation implying using the method GDA2020>WGS84 using null projection (EPSG:8450). As a side note customers using Geocortex require services to be published in the same datum as their basemap datums so the getcaps would need to specify GDA2020.  P.S a dedicated GDA2020 section in communities would be great 🙂 Kylie ...
