概要
Creates a linear referencing system (LRS) in the specified workspace using existing datasets.
使用法
Minimum schema items are used for the centerline, centerline sequence, calibration point, and redline feature classes. They should be contained in the same geodatabase and should not be 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 should be the same.
The centerline and calibration point feature classes should be z-enabled and not m-enabled.
The redline feature class should not be z- or m-enabled.
