Summary
Modifies the properties of an intersection feature class, such as fields and intersecting layers, that compose the intersection feature class and can be added or removed.
Usage
The input Intersection Feature Class parameter value should be a feature layer and cannot be a service layer.
This tool can be used on a feature class without geometry or records.
The spatial reference, tolerance, and resolution of the Intersection Feature Class and Intersecting Layers parameter values must match.
The Intersection Feature Class and Intersecting Layers parameter values must be in the same workspace.
Feature classes provided as Intersecting Layers must be z-enabled.
The sum of Intersecting Layers field lengths must be less than or equal to the Intersection Name Field length.
The Intersection Feature Class must have the following fields configured:
Field Data type Character length Nullable Description IntersectionId
Field (Guid)
38
No
An automatically generated field providing a unique ID for each intersection.
IntersectionName
String
1000
Yes
A concatenated field showing the descriptors for the route and intersecting feature.
RouteId
String
1000
No
The route ID of the route network.
FeatureId
String
1000
Yes
The ID of the intersecting feature.
FeatureClassName
String
150
No
The name of the feature class that participated in the intersection.
FromDate
Date
NA
Yes
The From Date of the route.
ToDate
Date
NA
Yes
The To Date of the route.
Measure
Double
NA
Yes
The measure on the base route at the point of intersection.

route_id_field (Optional) | The field in the Intersection Feature Class that contains the unique route ID. | Field |
feature_id_field (Optional) | The field in the Intersection Feature Class that contains the ID of the intersecting feature. | Field |
feature_class_name_field (Optional) | The field in the Intersection Feature Class that contains the name of the feature class that participated in the intersection. | Field |
from_date_field (Optional) | The field in the Intersection Feature Class that contains the from date of the route. | Field |
to_date_field (Optional) | The field in the Intersection Feature Class that contains the to date of the route. | Field |
intersecting_layers [intersecting_layers,...] (Optional) | The Intersection Feature Class fields that compose the intersecting layer.
| Value Table |
measure_field (Optional) | The field in the Intersection Feature Class that contains the measure on the base route at the point of intersection. | Field |
Derived Output
| Name | Explanation | Data Type |
| out_feature_class | The updated Intersection Feature Class. | Feature Class |
