transferAttributesPolygonsToPolylines

Transfer Attributes Polygons To Polylines

Transfers the selected attributes from a polygon dataset to the target polyline dataset. If a polyline intersects the boundary between two polygons, it is split and each part of the polyline gets the attributes of the appropriate polygon. The original attributes of the polylines are updated after splitting using user defined attribute update rules for each field. Address and continuous ranges split rules are supported.

Inputs

A polyline layer which features are to be split
A polygon layer which attributes will be transferred.
Attribute update rules for each field. See Split Polyline With Layer function for details.
List of the polygon attributes to be transferred.

Outputs

A polyline feature class - a node created in each intersection point between the features from the input polyline layer and the reference polygon layer. The output polylines will have the selected polygon attributes added.

Notes:

Range attributes from string and numeric fields can be handled.The records that have range values containing non numeric characters will be copied to the resulting features.
Polylines (and parts of them) that do not intersect the reference polygons will get empty attributes in the added fields.

Examples:

Original polylines overlayed with the polygon dataset

Before Split

Resulting polylines lebeled with the attributes transferred from the polygons

Parameters

Expression	Explanation
Function Name	TransferAttributesPolygonsToPolylines
<input dataset>	A String representing the input layer. Must be of Polyline Type.
<Reference Dataset>	A String representing the reference layer. Must be of Polygon Type
<output dataset>	A String - the full name of the output layer.
{Update Rules}	A String representing a list (separator ";") of fields and update rule for each field. Example: "Field1 AddressRange Field2; Field3 Copy; Field4 Proportion"
{Transfer Fields}	A String representing a list of the fields which attributes will be transfered. If empty, all polygon attributes will be transfered.

Running the function

ETGWPath used in the table below is the full path to ETGWRun.exe (E.G. "C:\Program Files\ETSpatial Techniques\ETGeo Wizards\ETGWRun.exe")

Language	Syntax
Python	subprocess.call([ETGWPath, "TransferAttributesPolygonsToPolylines", "input dataset", "Reference Dataset", "output dataset", "Update Rules", "Transfer Fields"])
.NET using ETGWRun.exe	StartInfo.FileName = ETGWPath StartInfo.Arguments = "TransferAttributesPolygonsToPolylines" "input dataset" "Reference Dataset" "output dataset" "Update Rules" "Transfer Fields"
.NET using ETGWOutX.dll	TransferAttributesPolygonsToPolylines(input dataset,Reference Dataset, output dataset, Update Rules,Transfer Fields)
ArcPy	arcpy.TransferAttributesPolygonsToPolylines(input dataset, Reference Dataset, output dataset,"Update Rules", "Transfer Fields")

Notes:

<> - required parameter
{} - optional parameter
See examples for Python , .NET or ArcPy
The argument separator for StartInfo.Arguments is space. If a string might contain a space, you need to double quote it.
