Synthèse
Overlays one or more linear event feature layers onto a target network and outputs a feature class or table that represents the dynamic segmentation of the inputs.
Utilisation
All input Event Layers must be line events.
The Event Layers parameter can only include linear event feature classes registered with an ArcGIS Location Referencing network.
If the input events use different linear referencing methods (LRM), they will be translated using the LRM of the target network.
This tool supports selection sets.
This tool supports definition filters.
This tool supports input Event Layers that are configured to contain events that span multiple routes. The output will still dynamically segment at the route level of the target network using the Network Fields parameter.
This tool supports temporal segmentation (time slicing). This will occur by default and can be overridden by creating a time-based definition query or applying a selection set to the inputs.
This tool supports including one or more fields from the network feature class in the output using the Network Fields parameter.
The output can be saved as either a table or a feature class.
If saved as a table or feature class, the output will have the following indexes and fields:
Index Field Route_ID
- Route_ID
Rid_Dates_Me
- Route_ID
- From_Date
- To_Date
- From_Measure
- To_Measure
If the target LRS Network is configured as a line network with support for a multifield route ID, the following parameters are not required for appending routes:
- Route Name Field
- Line Name Field
This tool supports the Gas Utility Network Configuration pipeline feature layer as an input event layer if this feature class has been configured for use with an LRS using the Configure Utility Network Feature Class tool.
If more than one LRS Network exists in the Gas Utility Network Configuration, the measures for the input event layers will match the measures shown in the right column of the table below.
If the LRS with the Gas Utility Network Configuration contains The measures in the PipelineLine feature class belong to Line network, nonline network
