摘要
Translates the measures (m-values) of a point or line event layer from one linear referencing method (LRM) to another.
A use case for this tool would be to translate event data from a mile-based network to a kilometer-based network.
In addition to measures, the route associations of the event features may also be different between the two LRMs. The output of this tool is a feature class with the correct measures and route associations of the target LRS Network.
使用情况
The input event layer must be a point or line feature class.
This tool does not modify either input and will create a feature class as an output.
This tool supports one temporal representation at a time. Create a time-based definition query or apply a time-based selection set to the input event layer as well as the target LRS Network before running this tool. The time slider in ArcGIS Pro can also be used if time is configured for both of the input layers.
This tool supports translating events against routes with gaps.
If the target network is an LRS line network, also known as an engineering network, the input event layer can be translated even if the original network of the input event layer does not support the concept of lines.
The output feature class type—line or point—must match the input event layer type.
The tolerance and resolution settings for the input event layer should match those of the target LRS Network.
To identify matching conditions that occur during the translation, a field called Loc_Error is created in the output feature class containing values such as Multi-Match, Partial Match, No Match, and No Error.
The attribute fields of the input event layer are included in the output feature class.
If the target LRS Network contains concurrent routes, use the Concurrent Route Matching option.
If Route with matching Route ID is used with Concurrent Route Matching, the input event layer must be registered as an LRS event layer in ArcGIS Location Referencing.
This tool will perform a spatial overlay of the input event layer onto the target LRS Network to generate features for the input event along the target network. These features will contain the Route ID and measure information of that location on the route.
The input event layer and the target network should only represent a single point in time to obtain an accurate output. If the input event layer represents multiple points in time, set a filter using the time slider or use a definition query on the date columns.
The output data can be added to a new or existing LRS event by using the Append Events tool. If the input event layer contained multiple temporal representations and resulted in running this tool multiple times with different date filters, each of the outputs can be added to a single LRS event feature class using Append Events.
