Vertices - the vertices of all polygons will be converted to points.
Labels - the Label point is always located inside the polygon.
The algorithm makes sure that the point is not close to the boundary of
the polygon. Points created using this algorithm are suitable for
spatial transfer of attributes (See Smooth Polygons and Generalize
Centers - the Center points represent the centroid of a polygon. Therefore
sometimes they might be located outside of the polygon
Centers Inside - points representing the centroids of
the polygons. If the centroid occurs outside of the polygon, the point is moved to be in the
Remove Duplicate Points - the duplicate points created from the
vertices of two adjacent polygons will be represented by one point. Note
that if this option is used the attempt to convert back these points to
polygons will produce incorrect result
Calculate point Position along boundaries
If used the [ET_Order] field will be populated with the
relative location of the vertex (0 to 1) from the start of the
If not used, the [ET_Order] field will be populated with the
order of the vertex in the polygon ring (from 0 to number of vertices)
Preserve Z(M) available only if the input feature class is of
PolygonZ(M) type. If selected, the result will be of PointZ(M) type,
otherwise the result will be of plain points (no Z or M values)
New point layer
All the original attributes of the
polygons are transferred to the point attribute table
New fields are 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 (if the Calculate point Position option is used) or from
0 to number of vertices (if not). The value of this attribute can be used if the polygons have to be
recreated from these points. - only if "Vertices" conversion option is used
[ET_IDP] - 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. - only if "Vertices" conversion option is used
[ET_X] - the X coordinates of the resulting points
[ET_Y] - the Y coordinates of the resulting points
[ET_Z] - if the input feature class is of PolygonZ(M) type.
[ET_M] - if the input feature class is of PolygonZ(M) type.
See above for the use of the "Remove duplicate points" option
