Create LRS From Existing Dataset (Location Referencing)

Summary

Creates a linear referencing system (LRS) in the specified workspace using existing datasets.

Usage

• Minimum schema items are used for the centerline, centerline sequence, calibration point, and redline feature classes. Ensure that the items are empty, contained in the same geodatabase, and not used by another LRS in the geodatabase.

• Centerline, calibration point, and redline feature classes must reside in a feature dataset.

• The spatial reference, tolerance, and resolution of the centerline, calibration points, and redline feature classes must be the same.

• The centerline and calibration point feature classes must be z-enabled and can be m-enabled.

• The redline feature class must be z-enabled.

• When using an enterprise geodatabase as an input to this tool, the current database user cannot be SDE or DBO.
