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.
Syntax
arcpy.locref.CreateLRSIntersection(parent_network, network_description_field, intersection_feature_class_name, intersecting_layers, {consider_z}, z_tolerance)
Parameter | Explanation | Data Type |
parent_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_name | The name of the new intersection point feature class. | String |
intersecting_layers [intersecting_layers,...] | The feature class that intersects the LRS Network and contains the following information:
| Value Table |
consider_z (Optional) | Specifies whether z-values will be used when generating intersections.
| Boolean |
z_tolerance | The z-tolerance used to generate intersections. | Double |
Derived Output
Name | Explanation | Data Type |
out_feature_class | The registered output point feature class that will be m- and z-enabled. This feature class will be empty. | Feature Class |
