M Values Auto Update and Relationships

Miralem_Zeljo — Thu, 13 Feb 2025 17:49:41 GMT

We would like to see an enhancement that automatically updates M value without the need of right click set distance - X and Y values auto update. It would be nice to see M value update when you add vertices or extend route lines. Also, it would be really nice to update next segment to start the M value by using last segment end point M value and auto update if I modify previous segment. We are working on developing tool right now but I feel that this should be a functionality out of the box to allow referencing segments and chose option if I want to have M value entered manually or use previous segment end point as a start of the next line segment.

@Miralem_Zeljo Thanks for the idea post.

I assume you are using the core linear referencing capability in ArcGIS Pro. It will help to understand what industry segment, data type are you referencing. We see LRS in transportation, utilities, pipelines etc.

Hope you reviewed the options as documented at: Update route measures

Some of your use cases refer to advanced LRS functionality, viz. location referencing that is available with Pipeline Referencing and/or Roads and Highways

How to choose between linear referencing and location referencing

Recommend looking at the resources provided before custom development efforts.

Is there a way to achieve this without spending $4K on the Roads and Highways Extension? We only need the core functionality, not the full suite of features.
