I am using ArcGIS 10.2 version and I have polyline features, for this I have to add vertex at some distance (10mtr) and label the z value of that vertex.
Is there any tool or script available?
You can try to use the Densify tool which
Adds vertices along line or polygon features. Also replaces curve segments (Bezier, circular arcs, and elliptical arcs) with line segments.
