Polygon Z (M) To Point Wizard

Converts a polygon Z (M) data set to a point feature class

Inputs:

• A polygon Z (M) feature layer 

Outputs:

• New point feature class
  • New fields added to the point attribute table
    • [ET_Order] - the position of the point along the polygon's boundary. The value can be from 0 to 1. It indicates how far from the Start ( End ) point of the polygon is the point (e.g 0.5 indicates that the point is in the middle of the polyline that serves as a polygon boundary). The value of this attribute can be used if the polygons have to be recreated from these points.
    • [ET_ID] - the FID of original polygons. The values can be used to link the points back to the polygons.
    • [ET_IDR] - this is a unique number identifying each ring of the polygons. If a polygon with FID = 356 has 3 rings, the corresponding points will have values in this fields 356_0, 356_1 and 356_2. This field can be used to recreate the polygons from the points without loosing the rings.
    • [ET_Z] - is added and populated with Z values if the polygons are Z aware
    • [ET_M] - is added and populated with M values if the polygons are M aware

Notes :

• The points can be converted back to Polygon Z(M) useng Point To Polygon Z(M) Wizard
