# New route events based on existing route events' locations/values

The goal is continuous values along a line based on known values of certain segments along the line. I was pointed towards linear referencing an an approach, so am currently trying to derive the values of the empty route events from their two neighboring route events (probably a distance weighted average).

Problem:

I need to assign values to the empty route events based on neighboring route events' values. Are there any tools or extensions compatible with a basic license that would do this?

The most similar question I have come across is https://geonet.esri.com/thread/98223, but that was points, not lines (so not continuous like I want), and it used Calculate Geometry to calculate the X value, which I don't have and am not interested in, so I can't use calculate geometry like they did.

I read about linear interpolation methods, but they are much(!) more statistically complex than I have the skills or time to even consider.

Is there a better/non-linear referencing/non-gis option for accomplishing this?

• This looks like it needs linear referencing to me. For the first point where you are stuck what precisely did you try and where precisely are you stuck? I recommend removing anything unrelated to that particular problem from this question. – PolyGeo Sep 6 '17 at 20:33
• Thank you for responding! Posting actually jogged my brain on the first problem; I will do a spatial join of the shapefile my field of interest is in to the file my route events would be based on. I will have route events for the entire route and will need to calculate the field of interest in the even segments where there is no data. I hope that seems reasonable. I think I really need help with the second (now only) problem in my post: I can't figure out a way to interpolate data for points in between the segments with known values. – Erin Godwin Sep 7 '17 at 0:03
• I think your question may distil to whether there is a Basic license level workaround to Generate Near Table so I think you should keep editing to try and make what you are asking clearer. – PolyGeo Sep 7 '17 at 0:21
• That isn't the question I was trying to ask; Generate Near Table was just one tool I thought might be somewhat helpful for part of the process. I wanted to make clear some of the tools I had looked at/my thinking about the process and that any tool suggested would need to be included in the Basic license level. – Erin Godwin Sep 7 '17 at 2:32
• Perhaps you can work on tying your question text into your picture - at the moment the picture seems too simple to be of any help. – PolyGeo Sep 7 '17 at 3:00
