Measuring distance between multiple destinations and one starting point at once

Some more information can be found here: Python: Automating…

Snap points to a polyline?

Hello! I am trying to put together a map of historical and contemporary fish occurrences. Some of my GPS points are slightly off of the stream segment (polyline) that they are from. How do I snap these floating points to the line segment they are nearest to? I appreciate any kind of help or advice! I am using ArcMap 10.5.1

For example, one of the counties I am working on the roads are label NC xxxx. However, the table that I use to label the end map only has the number.

Make a new text field (ie Temp ), and calculate values for it using the python parser Temp = "NC " + !P_str_nam! If it check out, you can copy the result from temp back P_str_nam = !Temp!
