Implementation
Calculates some characteristics of the polygons from a polygon 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_Length  the length of the longest axis
in the units of the Spatial Reference of the input
feature class.
 ET Width  the length of shortest side of the
bounding rectangle aligned with the longest axis in the units of the Spatial Reference of the input
feature class.
 ET Circ  Circularity ratio  for a circle
the circularity will be 1. The thinner the polygon is the smaller the
circularity will be.
 ET Thick  Thickness ratio expressed as a ratio of the polygon area versus the area of its
minimum bounding square. The ratio will have value of 1 for a square. The smaller the value
is, the thinner the polygon is.
 ET_Parts  the number of parts that the polygon has
 ET_Holes  the number of holes in the polygon
 ET_HasArcs  if the polygon has true arc segments  1 otherwise  0
 ET_Vert  the number of vertices of the polygon
 ET_Depth  the distance from the deepest point (the center of the
maximum inscribed circle) to the polygon boundary. See
Polygon To Point and
Polygon To Maximum Inscribed
Circle functions
 ET_Fract  the fractal dimension (indication of the complexity) of
the polygon boundary. The value is between 1 and 2. The more
complex the polygon boundary is the larger the fractal dimension
will be.
Notes:

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

Calculating the Fractal Dimension and Polygon Depth is
time consuming. If you don't need these characteristics, uncheck the options
for faster processing.
