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

Paramètre | Explication | Type de données |
in_feature_class | The input LRS Network feature class to be modified. | Feature Layer |
route_id_field (Facultatif) | The field in the input feature class that will be mapped as the LRS Network route ID. The field type must match the RouteId field type of the Centerline_Sequence table and must either be a string or GUID field type. | Field |
route_name_field (Facultatif) | A string field in the input feature class that will be mapped as the LRS Network route name. | Field |
from_date_field (Facultatif) | A date field in the input feature class that will be mapped as the LRS Network from date. | Field |
to_date_field (Facultatif) | A date field in the input feature class that will be mapped as the LRS Network to date. | Field |
derive_from_line_network (Facultatif) | Determines if the current LRS network will be configured as an LRS Derived Network.
| String |
line_network_name (Facultatif) | The name of the LRS Line Network to which the input LRS Derived Network will be registered. The input LRS Line Network must reside in the same geodatabase workspace and LRS as the LRS network feature class. This parameter is only used if the derive_from_line_network parameter is set to DERIVE. | String |
include_fields_to_support_lines (Facultatif) | Determines if the current LRS network will be configured to support lines.
| String |
line_id_field (Facultatif) | The field in the input feature class that will be mapped as the LRS Network line ID. This parameter is only used if the include_fields_to_support_lines parameter is set to INCLUDE. The field type must match the RouteId field type of the Centerline_Sequence table and must either be a string of exactly 38 characters or a GUID field type. | Field |
line_name_field (Facultatif) | A string field in the input feature class that will be mapped as the LRS Network line name. This parameter is only used if the include_fields_to_support_lines parameter is set to INCLUDE. | Field |
line_order_field (Facultatif) | The field in the input feature class that will be mapped as the LRS Network line order. This parameter is only used if the include_fields_to_support_lines parameter is set to INCLUDE. This must be a long integer field type. | Field |
route_id_configuration (Facultatif) | Determines the route ID configuration for an LRS Network.
| String |
individual_route_id_fields [individual_route_id_fields,...] (Facultatif) | The individual fields in the in_feature_class that will be used to form the route ID. This parameter is only used if the route_id_configuration parameter's MULTI_FIELD_ROUTE_ID option is set. The fields must be either string or number integer field types. | Field |
