Polyline Characteristics

Implementation
Calculates some characteristics of the polylines from a polyline dataset
Inputs:
Outputs:
 The results can be added to the input feature
class or a new polygon feature class. All attributes of the
original features are preserved
 New fields added to the attribute table
 ET_Sinous  the sinuosity of the polyline calculated as ratio of
the length of the polyline and the length of the line connecting the start
and end points of the polyline. The value ranges from 1 (case of straight
line) to infinity (case of a closed polyline). In case of infinity a 0 is
recorded in the attribute table. See illustration below.
 ET_Vert  the number of vertices of the polyline
 ET_Dir  the general direction of the polyline  the direction in
decimal degrees measured in North Azimuth of
the line connecting the start and end points of the polyline (see
illustration below).
 ET_Parts  the number of parts that the polyline has
 ET_HasArcs  if the polyline has true arc segments  1 otherwise  0
 ET_Closed   if the polyline is closed  1 otherwise  0
 ET_Fract  the fractal dimension (indication of the complexity) of
the polyline. The value is between 1 and 2. The more complex the
polylineis the larger the fractal dimension will be.
Notes:

Fractal Dimension of the polylines is calculated using the
Box Counting method (1)

Calculating the Fractal Dimension is time consuming.
If you don't need this characteristic, uncheck the option for faster
processing.
