Can I label a points layer perpendicular to a line layer?

PaulWirth

I have a points layer (Electrical Transmission structures) and a Transmission line layer. The points layer sits on top of the line layer and because the line layer changes direction all the time it is hard to label the points layer sometimes. What I would like to do is label the points layer perpendicular to the line layer.

Does anyone have an answer for me?

It would be important to know what software you are using (and the version). Are you using desktop (Pro or ArcMap) or ArcGIS Online?

In case of Desktop, you could create a script to generate a field with the rotation based on the bisector. A few years ago I created a tool to define service areas of transmission tower applying the rotation based on the bisector (the green polygons in the image below):

The rotation determined by the tool could be written to the transmission towers and those can be used to define the rotation of the label. See the code below. The angles are determined on lines 51, 73 and 93.

Desktop 10.5.1 or ArcGIS Pro 2.1.1

I am not a big time programmer.

XanderBakker

Is it possible for you to share a sample of the data? I could have a look if I can adjust the script to what you need. The result would be an additional field with the rotation in the point layer.

PaulWirth

I have to look into it, but it might be possible. Which layer do you want? Points or Lines.

XanderBakker

It could (or should) be both. Or if the points follow the order (sequence) of the line one could determine the angles of the lines based on only the points. Otherwise, one has to determine the angles of both line parts based on the line. It also matter is the line is a single line, or each segment from tower to tower is a feature. Would be could to see the data to understand those aspects, since it determines how the code should be changed.

Hi, @XanderBakker !

Could I get a help with this script?

I have the same queastion as @Paul 😕

XanderBakker

Hi @GIS_Rookie ,

Then I suppose I have to reply with a question similar to the one I asked Paul. Do you have a sample of data that you can share? That will help understand what you have and what you are looking for.

MarcoConopio1

Hi @XanderBakker !

I am trying to run your script and I have some questions.

What is the fc_out shapfile? Is this the line shapefile to which the labels will be perpendicular to?
I tried running both of the script, with the assumption that the fc_out is the alignment to which the labels will be perpendicular to, and I keep getting this error

Thank you and would greatly appreciate any help!

XanderBakker

Hi @MarcoConopio1 ,

The error is pointing to the use of a field that does not exist in the featureclass. Can you check that the fields with names assigned to the variables "fld_orden" and "fld_label" exist in your featureclass?

OzzOutao_UoM

Hi, @XanderBakker . Thanks a lot for your script, it’s very useful.

I am having an issue with angles as when my ‘ANGLE2’ field gets populated the only value I get is: -116.907208734888 (for every row).
I am basically trying to draw a short line that will mark 1 km along the road. I have created points along the road, and now trying to label them with ‘___’.
I want this labels to be perpendicular to the road.
I have added two fields to my points shapefile (‘Pole’ with values as ‘___’ (data type: text), and “ANGLE2” with empty values (data type: double)).

Please take a look at the attached file for a visual explanation.

I will appreciate any advise, thanks!
