I have two lines (the center line of a tunnel) that lack z values, they are currently just flat lines with start and end xy values. I do have the z values in points - but how do I get the values from the points to the lines? I have the basic license and cannot use the Split Line at Point tool.
I would like the lines to be split at each point and assigned a z value. I have two lines and approximately 400 points, the elevation of the tunnel differs between a few meters below sea level and 90 meters above.
I am using arcmap for desktop 10.3.1
Thanks in advance.
