Modify Network Calibration Rules (Location Referencing)

サマリー

Modifies the network calibration rules for an LRS Network.

When creating an LRS Network, you can choose how gapped routes are calibrated while creating or editing routes. Using this tool, you can configure calibration rules for a network after the LRS Network has been created and during the data loading process.

Learn more about creating and modifying an LRS Network in ArcGIS Pipeline Referencing or creating and modifying an LRS Network in ArcGIS Roads and Highways.

You can use any of the following methods to calibrate routes with physical gaps:

• Stepping Increment
• Adding Increment
• Euclidean Distance

Each method will produce a different calibration value for a route with physical gaps created using the LRS editing tools. The example below shows the calibration of a route created from a centerline with physical gaps for each calibration method and calibration of a route with retirement between the measure 0.5 and 1 for each calibration method.

In the retire route scenario, a physical gap is created between the measures 0.5 and 1. The calibration rules are applied only if a physical gap is introduced due to an editing activity and do not affect the existing gaps. In the example, the gap between measures 2 and 2.5 remains unaffected due to retirement.

使用法

• The following tables show the results of gap calibration using the Create Route and Retire Route panes after setting up rules using this tool.

  増分値のステッピング (0.1)		各物理的ギャップの後の最初のメジャーに、メジャー値 0.1 が追加されます。
  増分値の追加 (0.1)		各物理的ギャップの後の各メジャーに、メジャー値 0.1 が追加されます。
  ユークリッド距離		各物理的ギャップの後の最初のメジャーに、物理的ギャップの直線距離に等しいメジャー値が追加されます。

  メジャー 0.5 〜 1 の間のルートを廃止します。

• This tool supports setting the gap calibration rule and the calibration offset for the specified network.

• Typically, network calibration rules can be modified once the network is created. Changing the calibration rule will apply the new rule only to routes edited or loaded in the future. All routes edited or loaded previously will not honor the new calibration rule. They honor the calibration rule set at the time of their creation or editing.

• You can use the As Is option in the Calibration Rule parameter to retain the existing gap calibration method with an option to change only the calibration offset value pursuant to requirement.

• The Calibration Offset parameter must be set for the adding increment and stepping increment methods. The values must be numeric, with or without decimals; negative values cannot be used.

• The Calibration Offset parameter value cannot be set less than or equal to the m-tolerance of the network. It can be either zero or greater than the m-tolerance value of the network.

• Defining the Calibration Offset parameter value as zero (0) will produce a route with no gap in calibration measure at physical gaps.

• The default gap calibration rule for an LRS Network is Stepping Increment with an offset value of 0.

• This tool is not supported with feature services.
