When you mix older datums like NAD27, OSGB 1936, DHDN, etc, then larger offsets occur. </SPAN><BR /><BR /><SPAN>Web mercator Auxiliary Sphere 3857 (which our basemaps use)&nbsp; is on WGS84.</SPAN><BR /><BR /><SPAN>thanks,</SPAN><BR /><BR /><SPAN>Mike</SPAN></BODY></HTML> Thu, 19 Jun 2014 22:27:18 GMT https://community.esri.com/t5/arcgis-online-questions/problems-with-drag-and-drop-for-csv-files/m-p/264239#M12926 MikeMinami 2014-06-19T22:27:18Z
