Hi, this is my hosting layer :https://services3.arcgis.com/AunWwdsIxAljj0av/arcgis/rest/services/mus_pipelines/FeatureServer
I got these weird line in map
I am very sure my data doesn't have these odd line. please can anyone check this issue?
What's the coordinate system of the original data, and what is the data source, where did it come from and how did you get it into ArcGIS Online? It's probably some transformation issue on publishing or invalid geometries or some sort of error with true curves being densified.
Also the feature service link you shared isn't public so only you or your organisation members can see it currently.
