perpendicularsToPolylines

Perpendiculars from Points to Polylines

Draws a perpendicular polyline from each point to the closest polyline from the reference layer and calculates several attributes for each perpendicular line.

Inputs:

A point feature class
A reference polyline feature class
Search tolerance.

Outputs:

New Polyline feature class with lines from the source points and perpendicular to the closest polyline from the reference feature class.
The attributes of the original points are transferred to the resulting lines.
The following fields are added to the attribute table of the resulting feature class.
- [ET_Dist] - the distance from the original point to the closest polyline (the length of the perpendicular line)
- [ET_Pos] - the relative position of the original point along the closest polyline (in percent)
- [ET_Angle] - the angle (0 to 360) of the resulting perpendicular line in degrees starting North clockwise
- [ET_Station] - the absolute position of the original point along the closest polyline (in the units of the spatial reference of the input point feature class)
