Zusätzliche Informationen

The SDK documentation for geometryEngine.simplify(), geometryEngineAsync.simplify() and simplifyOperator, at versions 4.31 and prior, incorrectly stated that these methods treated self-intersecting polylines as not simple. The esri/rest/geometryService simplify() method also uses the same functionality internally. We are in the process of updating the documentation to clarify that these methods are non-OGC compliant. This means these methods treat self-intersecting polyline paths as simple (simple = true). Using these methods to simplify polylines will not break up the polyline paths at self-intersection points. An important clarification: these methods do treat self-intersecting polygon rings as not simple (simple = false). We are considering adding an OGC-compliant operator to accommodate this use case.

Workaround

Depending on the use case, a possible workaround is to utilize the Arcade function IsSelfIntersecting, which can be found at this link: https://developers.arcgis.com/arcade/function-reference/geometry_functions/#isselfintersecting. You can implement this function through the following resource: https://developers.arcgis.com/javascript/latest/api-reference/esri-arcade.html.
