| Error Code | Error description |
|---|---|
10 | The feature has an empty geometry. |
11 | The feature's geometry has multiple parts. |
12 | The feature's begin and end vertex are the same. |
13 | The feature has a geometry with zero length. |
14 | The edge feature is associated with the same from–to junction feature. |
15 | The junction is coincident with an edge–feature vertex having a different z-value. |
16 | The junction is not connected to any other edge feature. |
17 | Edge features prevented from collapsing on themselves because their length is near the snapping tolerance. |
