Create LRS Intersection (Location Referencing)

Summary

Creates an intersection feature class for an existing LRS Network.

The output of this tool is an empty feature class with fields that conform to the LRS data model.

Run the Generate Intersections tool to generate intersection points after using this tool.

Usage

• The projected coordinate system of the intersecting feature classes must match that of the Parent LRS Network parameter value.

• The Parent LRS Network parameter value can be used as an intersecting layer, so the intersections produced will be between the routes in a network.

• The Parent LRS Network parameter value cannot be a feature service.

• The intersecting layers must be in the same geodatabase as the Parent LRS Network parameter value.

• The name of the intersection is created by concatenating the Network Description Field parameter value with the Description Field value in the Intersecting Layers parameter, separated by the Name Separator value in the Intersecting Layers parameter.

• The Intersecting Layers parameter value must be z-enabled.

• When using an enterprise geodatabase as an input to this tool, the current database user cannot be SDE or DBO.

• Only a comma (,) is allowed as a name separator for route-on-route intersections.

Parameters

Dialog

Label	Explanation	Data Type
Parent LRS Network	The network to which the intersection will be registered.	Feature Layer
Network Description Field	The field in the network layer that will be used to name the intersections with other intersecting layers.	Field
Intersection Feature Class	The name of the new intersection point feature class.	String
Intersecting Layers	The feature class that intersects the LRS Network and contains the following information: Intersection Layer—The feature class that intersects the LRS Network. ID Field—The field in the intersecting layer used to uniquely identify the feature that intersects the network. Description Field—The field that provides the description, such as town or county name, of the intersecting feature. Name Separator—The name separator for the intersection, such as AND, INTERSECT, +, or |.	Value Table
Consider z-values when generating intersections (Optional)	Specifies whether z-values will be used when generating intersections. Checked—Z-values will be used when generating intersections. Unchecked—Z-values will not be used when generating intersections. This is the default.	Boolean
Z Tolerance	The z-tolerance that will be used to generate intersections.	Double
