We take data from arcgis online map with coords like [8530892.9655853795422690.331037998spatialReference{wkid102100latestWkid3857} (as on screenshot). Then use online converter to get coords for Google Earth (EPSG:3857 WGS 84 / Pseudo-Mercator -> EPSG:4326 WGS 84). And see mismatch for about 65 meters (on 2nd screenshot). Why? How to align coordinates.

As I've said before, the G in GIS isn't Google...

Is 65 meters an issue for you?  I mean do you need better precision than that? If so perhaps you need to consider a different work flow for your conversions.  Remember too that various projections and spatial references may and often times do use different datums.  Consequently, a conversion may induce 'error'.

That should just about do it....

We are installing drip irrigation and even 5 meters is an issue. Is it possible to obtain google-compatible coordinates using the source data?
