Extract stream link junctions?

[808707]

Is there anyway to create a point layer of junctions as seen in the diagram in the link below?

Have you considered running a Focal Statistics (variety option)?  Anywhere that there is a difference in the branch values should get you pretty close to the branch location (then convert to vector)

One of the Arc Hydro processing steps creates Drainage Points. This gives you two points near each junction. They are not on top of each other.

The other thought I had was to use Data Management Tools.tbx\Features\Feature Vertices To Points to created points at the ends of each line feature. The assumption here is that the upstream end of your stream polygon is snapped to the downstream end of the next polygon.

To eliminated duplicates (points on top of each other) use Data Management Tools.tbx\General\Delete Identical w/o specifying any fields to compare.

Great thanks to you both! I'll give those methods a try and see how it goes!

Merry Christmas!!

Feature Vertices to Point with  BOTH_ENDS will probably do what you want, though you may have some un-duping to do for from and to points at the same location.
