An overview of the Location Referencing toolbox

Roads and Highways is a data management application suite that provides an integrated framework for maintaining highway data with linear referencing systems. The Location Referencing toolbox provides essential Roads and Highways tools for regenerating routes, managing calibration points and events, and executing quality control checks.

Tools in the Location Referencing toolbox.

Tool name	Description
Append Events	Appends event records from a table, layer, or feature class into an existing Esri Roads and Highways event feature class.
Calculate Route Concurrencies	Calculates and reports the concurrent route segments in an LRS Network.
Convert M-Value Units Of Measure	Converts the measure m-values of a dataset from one unit to another. The m-values of the input dataset are modified upon executing this tool.
Convert Table To CSV File	Converts a table to a CSV file.
Delete Routes	Deletes routes and associated data elements from the LRS Network.
Detect Gaps For Linear Events	Checks routes on the network for gaps between linear events.
Detect Measures Out Of Range	Checks routes on a network for out-of-range line and point event measures.
Detect NonMonotonic Routes	Checks routes for nonmonotonic calibration of the m-values on vertices. Nonmonotonic calibration occurs when a route does not contain either strictly increasing or strictly decreasing m-values on its vertices.
Detect Overlaps For Linear Events	Checks routes on the network for overlaps between linear events.
Generate Events	Re-creates shapes for event features registered with an LRS Network. If the event has derived network route and measure fields configured, the tool will update those fields when executed.
Generate Routes	Re-creates shapes and applies calibration changes for route features in an LRS Network.
Overlay Route Events	Overlays two or more linear event feature layers against a target network and outputs a feature class or event table that represents the dynamic segmentation of the inputs.
Relocate Events	Lists changes that have been made to event record measures during a period of time. External systems can use this information at regular intervals to sync to route edits in the Esri Roads and Highways network.
Translate Events From LRM To LRM	Translates the measures (m-values) of events from one linear referencing method (LRM) to another. The output is a new event layer feature class.
Update Calibration Points	Builds calibration point features when an advanced linear referencing system already exists in the geodatabase.
Update Intersection Points	Helps generate and update LRS intersection point features.
