Generate Calibration Points (Location Referencing)

Disponible avec la licence Location Referencing.

Synthèse

Generates calibration points for any route shape provided, including complex shapes such as self-closing, self-intersecting, and branched routes.

Utilisation

• An LRS dataset is required to run this tool. To create an LRS dataset, add the calibration point, centerline, and redline layers to a feature dataset; then run the Modify LRS tool with the geodatabase as the input.

• Input Polyline Features are the basis for the calibration points that will be generated.

• Calibration Point Feature Class must be registered with the LRS.

• LRS Network must be registered with the LRS.

• Derived LRS Networks are not supported as the LRS Network.

• Z-values are considered when calculating the geometric length of the centerlines.

• Gap calibration rules are followed when generating calibration points.

Input Polyline Features	The features that will be used as the source to calculate the measure values for calibration points.	Feature Layer
Route ID Field	The field containing values that uniquely identify each route. The field type must match the Route ID field in the calibration point feature class.	Field
From Date Field	The field containing the From Date values of a route.	Field
To Date Field	The field containing the To Date values of a route.	Field
Calibration Point Feature Class	The existing calibration point feature class to which new features will be added.	Feature Layer
LRS Network	The LRS Network for which the measure values will be generated in the calibration points feature class.	String
Calibration Direction (Facultatif)	Specifies the direction of increasing calibration on a route when creating new calibration points. Digitized direction—The direction of digitization of the Input Polyline Features determines the direction of calibration for the route. This is the default. Measure direction—The direction of increasing m-values of the Input Polyline Features determines the direction of calibration for the route. If Input Polyline Features does not include m-values, the digitized direction will be used instead.	String
Calibration Method (Facultatif)	The method used to determine the measures on a route when creating calibration points. Geometry length—Only geometry length is supported as the calibration method.	String
