Create LRS Network From Existing Dataset (Location Referencing)

Disponible avec la licence Location Referencing.

Synthèse

Creates an LRS Network using an existing polyline feature class.

Utilisation

• Creates an LRS Network in an ArcGIS Location Referencing linear referencing system (LRS).

• The input feature class must be empty and reside in a feature dataset that contains an LRS dataset. The input feature class must not already be registered with an existing Location Referencing LRS Network.

• If the input workspace contains more than one LRS, the selected LRS will be used for network registration.

• The input feature class name must be 26 or fewer characters.

• The x,y resolution and x,y tolerance of the input feature class must match the resolution and tolerance settings of the Location Referencing LRS.

  Learn more about Tolerance and resolution settings for the LRS in ArcGIS Pipeline Referencing and tolerance and resolution settings in ArcGIS Roads and Highways.

• The unit of measure and m-tolerance for the output LRS Network will be derived from the centerline feature class spatial reference within the input feature class workspace.

• By default, the tool will output an LRS Network that does not support lines. To create an LRS Network that supports lines, enable the Include Fields to Support Lines parameter and map the additional fields required for an LRS line network (line ID, line name, and line order). To create an LRS derived network, enable the Derive From Line Network parameter and provide the LRS line network to which the LRS derived network will be registered.

• This tool does not alter the input feature class and will instead add information to internal metadata tables to register the input feature class as the LRS Network feature class.

• A feature class can only be registered as one LRS Network feature class at a time. Delete the LRS Network to which a feature class is registered to use a feature class that is already registered.

• An input field can only be mapped to one LRS Network field parameter at a time.

• The output of this tool is an LRS Network that will reside in the same workspace as the input feature class.

• The route ID can be a single field or a concatenation of multiple fields. If the network uses a concatenated route ID, all of the fields that compose the route ID must be present in the network feature class.
