Create LRS Intersection From Existing Dataset (Location Referencing)

Zusammenfassung

Registers an existing intersection feature class as an intersection.

Verwendung

• 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 Intersection Feature Class parameter value and 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 Intersection Feature Class fields must include the properties outlined in the LRS data model.

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

Parameter

Beschriftung	Erläuterung	Datentyp
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 input point feature class to be registered.	Feature Layer
Intersection ID Field	The ID field in the Intersection Feature Class. The field must have a unique ID for each intersection for a time slice.	Field
Intersection Name Field	The field in the Intersection Feature Class that is a concatenated field showing the descriptors for the route and the intersecting feature.	Field
Route ID Field	The field in the Intersection Feature Class that contains the route ID for the LRS Network.	Field
Feature ID Field	The field in the Intersection Feature Class that contains the ID for the intersecting feature.	Field
Feature Class Name Field	The field in the Intersection Feature Class that contains the name of the feature class that participated in the intersection.	Field
From Date Field	The from date field in the Intersection Feature Class.	Field
To Date Field	The to date field in the Intersection Feature Class.	Field
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 during generation of intersections. Unchecked—Z-values will not be used during generation of intersections. This is the default.	Boolean
Z Tolerance	The z-tolerance used to generate intersections.	Double
Measure Field	The measure on the base route at the point of intersection.	Field
