The split control can be configured to listen for edits on any vector layer
|
|
or it can allow for creation of temporary sketch features. Modified or
|
|
newly drawn features will be used to split existing features on any target
|
|
layer. This example shows the split control configured to use temporary
|
|
sketches for the split.
