Update Calibration Points

概要

Builds calibration point features when an advanced linear referencing system already exists in the geodatabase.

使用法

• Input Polyline Features is used as a source linear referencing method for calculating the measure values to update the calibration point feature class.

• The Measure Tolerance parameter is only used when you choose to update measures on existing calibration points.

• If the existing measure lies within the tolerance of the calculated measure, the measure on the calibration point will not be updated.

パラメーター	説明	データ タイプ
in_polyline_features	The Input Polyline Features that will be used as the source to calculate the measure values for the calibration points.	Feature Layer
in_routeid_field	The field containing values that uniquely identify each route. Long, Short, Text, GUID, and GlobalID field types are supported.	Field
in_calibration_point_features	The calibration point feature class in which new features will be added and existing features will be updated.	Feature Layer
in_lrs	The advanced linear referencing system with which the calibration point feature class is associated.	String
in_network	The LRS Network layer for which the measure values need to be generated and updated in the calibration points feature class.	String
in_calculation_method	The method used to calculate measure value for calibration points being updated. M_ON_ROUTE_2D —Measure values on input route feature (PolylineM) M_ON_ROUTE_3D —Measure values on input route feature (PolylineMZ) GEOMETRY_LENGTH_2D —Shape length of input route feature (PolylineM) GEOMETRY_LENGTH_3D —Shape length of input route feature (PolylineMZ) ATTRIBUTE_FIELDS_2D —Measure values stored in attribute fields of input route feature (PolylineM) ATTRIBUTE_FIELDS_3D —Measure values stored in attribute fields of input route feature (PolylineMZ) INTERPOLATE_EXISTING —Measures on existing calibration points are used to interpolate new measure values	String
in_update_method	This method determines which calibration point features get updated. UPDATE_NONE —None of the existing calibration points gets updated but creates new calibration point features as required for a correct calibration of the route. UPDATE_END_CALIBRATION_POINTS_ONLY —Update all existing calibration points at the end of the contiguous part of the route. UPDATE_ALL_EXISTING_CALIBRATION_POINTS — Update all existing calibration points along the route.	String
in_search_tolerance	New calibration points will not be created at the end point of a route if another calibration point already exists within the Search Tolerance.	Double
in_measure_tolerance	All existing calibration points that fall within this measure tolerance will not have their measure values updated.	Double
in_from_date_field (オプション)	The field containing the From Date values of a route.	Field
in_to_date_field (オプション)	The field containing the To Date values of a route.	Field
in_from_measure_field (オプション)	The field containing the From Measure of a route. This parameter becomes active if the Calculation Method parameter is set to ATTRIBUTE_FIELDS_2D or ATTRIBUTE_FIELDS_3D.	String
in_to_measure_field (オプション)	The field containing the To Measure of a route. This parameter becomes active if the Calculation Method parameter is set to ATTRIBUTE_FIELDS_2D or ATTRIBUTE_FIELDS_3D.	String

This parameter becomes active if the Calculation Method parameter is set to GEOMETRY_LENGTH_2D or GEOMETRY_LENGTH_3D. DIGITIZED_DIRECTION —Follows the direction of digitization on the input route features. This is the default. MEASURE_DIRECTION —Follows the increasing measure values on the input route features. Should only be selected if input route features have measure values.	String
in_gap_calibration_type (オプション)	Determines the method for calibrating physically gapped routes based on the input route features. This parameter becomes active if the Calculation Method parameter is set to GEOMETRY_LENGTH_2D or GEOMETRY_LENGTH_3D. STEPPING_INCREMENT —Adds a step to the calibration of physically gapped routes. This is the default. ADDING_INCREMENT —Adds an increment to the gap and total length of physically gapped routes. ADDING_EUCLIDEAN_DISTANCE —Adds Euclidean distance to the calibration of physically gapped routes.	String
