select points on outline of polygon

HannesZiegler2

I have a situation where I need to select points that are located on the outline of a polygon (not within, directly on the outline). I looked through the "Select by Location" documentation but there does not seem to be an option for this case. Does anyone have any idea on how to accomplish this?

Thank you!

Thank you. I've found the reason why all my points are selected after trying your method and still getting points inside of parcels. It's because I have multipoint features. I've converted them to singlepart features using "Multipart to SinglePart" and now get the results I need.

One option could be Converting Polygon to Line feature (Requires ArcGIS Desktop Advanced license). Then using "Intersect" as the relationship type between Line and Point (Select by Location).

Doesn't "touch the boundary of the source layer feature" give the results you are after? The outline of a polygon is its boundary, so only a point on the outline will be selected using "touch the boundary of the source layer feature."

I guess that relationship type takes only Lines and Polygons as input, not points.

I'd go with the suggestion by bixb0012 .

The target layer can be points.

HannesZiegler2

Yes, I thought so as well, but when I used this option, I got the results you see in my screenshot 😕

*EDIT*

Aha! I've found the reason why both points are selected. They are multipoint features.

Can you do another screenshot? I am unclear about a couple points of your current one. For example, what is that horizontal red line? Also, what are the boxy black areas?

When you run the tool using the aforementioned condition, are both points getting selected or neither?

HannesZiegler2

The red lines are virtual laterals. However, I've found the solution, and it wasn't a problem with the selection. I had multipart features and so multiple points were being selected, not just the ones on the boundary. Thank you to all who answered my question, I really appreciate the help!
