Polygon To Point Wizard
Converts a polygon data set to a point feature class
Inputs:
- A polygon feature layer
- Conversion option
- Vertices - the vertices of all polygons will be converted to points. If the "Remove
duplicate points" option is selected 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
- 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
Polygons functions).
- 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
polygon.
Outputs:
- New point feature class.
- 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. 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. - only if
"Vertices" conversion option is used
- [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. - 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
Notes :
- See above for the use of the "Remove duplicate points" option
