Modify LRS Network (Location Referencing)

Location Referencing ライセンスで利用可能です。

サマリー

Modifies an LRS Network in a Location Referencing linear referencing system (LRS).

使用法

• The input feature class must represent a Location Referencing LRS Network.

• This tool does not delete any LRS Networks, feature classes, fields, or data.

• This tool updates internal metadata tables that store information about the input LRS Network.

• This tool allows the remapping of LRS Network fields such as route ID, route name, date, and measure fields. If line support is enabled, the line ID, line name, and line order fields can also be remapped.

• Any new fields that will be used for field mapping should be created in the underlying LRS Network feature class before using this tool.

• The ability for an LRS Network to support lines, such as for an engineering network, can be added or removed with this tool.

• If a network that supports lines is present in the geodatabase workspace of the input LRS Network, an LRS Derived Network can be configured with this tool. An existing LRS Derived Network can also be unregistered from an LRS Line Network and registered with a different LRS Line Network.

• A field from the input LRS Network can only be mapped to a single LRS Network field.

• The Route ID Field 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 should be present in the network feature class.

• The ability for an LRS Network to support a user-generated route ID network can be added or removed with this tool.

Autogenerated Route ID—The route ID field will be an autogenerated GUID, and the route name can be configured as an LRS field. Single-Field Route ID—Supported only for nonline networks. Multi-Field Route ID—Supported only for nonline networks. More than one field is needed to form the concatenated route ID.	String
Field(s) (オプション)	The individual fields in the LRS Network Feature Class that will be used to form the route ID. This parameter is only used if the Route ID Field Configuration parameter's Multi-Field Route ID option is set. The fields must be either string or number integer field types.	Field
