Polygon Characteristics

Calculates some characteristics of the polygons from a polygon dataset

Inputs:

• A Polygon feature class

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.
