Create LRS Network (Location Referencing)

サマリー

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

使用法

• The input workspace must contain a Location Referencing LRS.

• If the input workspace contains more than one Location Referencing LRS, a drop-down menu is provided to choose the LRS to which the network will be registered. Any valid LRS in the input workspace can be entered in a Python script.

• The LRS Network name must be 26 or fewer characters and cannot contain any special characters other than underscores.

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

• The unit of measure (m-units) for the output LRS Network can be set to a unit other than that of the spatial reference.

• The default output of this tool is an LRS Network that does not support lines, along with a feature class that does not contain the necessary fields to support lines. If you want an LRS network that supports lines, check the Include Fields to Support Lines parameter and map the additional fields required for an LRS line network. If you want an LRS derived network, check the Derive From Line Network parameter and provide the LRS line network to which the LRS derived network will be registered.

• This tool will add information to internal metadata tables to register the output feature class as the LRS Network feature class.

• A feature class can only be registered as one LRS Network feature class at a time. If a feature class is already registered and that name must be used as the output feature class name, delete the LRS Network to which the feature class is registered.

• A field in the output feature class can only be mapped to one LRS Network required field.

• The output of this tool is an LRS Network and an empty polyline feature class that will store the routes of the LRS Network.

• The output LRS Network and output feature class will have the same name as defined by the LRS Network Name parameter.
