Modify LRS Intersection (Location Referencing)

摘要

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.

使用情况

  • 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:
