Converts a polyline data set to a point feature class
Inputs:
A polyline feature layer
Conversion option
Vertices - the vertices of all polylines will be converted to points. If the
"Remove duplicate points" option is selected the duplicate points created from
the nodes of two polylines sharing a common node will be represented by one point. Note
that if this option is used the attempt to convert back these points to polylines will
produce incorrect result.
Nodes - only the nodes of each polyline will be exported.
Middle points - only the middle point of each polyline will be exported.
Outputs:
New point feature class
All the original attributes of the
polylines are transferred to the point attribute table
New fields are added to the point
attribute table
[ET_ID] - the FID of original polylines. The values can be used to link the points back
to the polylines.
[ET_IDP] - this is a unique number identifying each
part of the polylines. If a polyline
with FID = 356 has 3 parts, the corresponding points will have values in this fields
356_0, 356_1 and 356_2.
[ET_X] - the X coordinates of the
resulting points
[ET_Y] - the Y coordinates of the
resulting points
If the conversion option is "Vertices" or "Nodes"
an Order field is added
[ET_Order] - the position of the point along the polyline . The value can be from 0 to
1. It indicates how far from the Start point of the polyline is the point (e.g 0.5
indicates that the point is in the middle of the polyline). The value of this attribute
can be used if the polyline have to be recreated from these points.
If the "Assign angle
attribute" option is used an angle field is added
[ET_Angle] - the angle of the polyline in this point.
Notes :
See above for the use of the "Remove duplicate points" option
If the "Assign angle attribute" option is used, the points symbols can be
rotated and in such a way can represent the direction of the polylines. See the example
below
