I am doing some test in ArcGIS online to know how much helpful it is for my firm, But when I opened my road line .Zip shapefile in ArcGIS online it is showing some snapping issues as well as changed the shape of the roundabouts. (road line does not have any problem in Desktop GIS softwares) Anyone can help me to know what is actually happening with files when I open it in ArcGIS Online.
ArcGIS Desktop
ArcGIS Online
Both are same vector file, but the first one is in ArcGIS Desktop and Second image is in ArcGIS Online.
