Editing point or linear events

Point events typically represent occurrences along a route, such as incidents that have been reported on a highway, or flow gauges along river reaches. Linear events can be used to model portions of routes. You can modify line or point events if your map administrator has configured the functionality. See the related topics below to add a new point or line event, delete an existing point or line event, merge two point events or line events into one, split line events or point events into two.
