Feature Description

Extract M Values refers to extracting scale values from route data at specified intervals. The extraction result is point data, which can be used to label M values of route data on maps, helping users understand the route values of each segment.

Feature Entry

• In the Transport Analysis Tab -> Dynamic Segmentation group, click the Extract M Values button.
• Toolbox -> Transport Analysis -> Dynamic segmentation tools: Extract M Values; or drag this tool to the model builder window and double-click the feature icon.

Parameter Description

• Source Dataset: Set the target route dataset and its datasource in the dialog.
• Route ID Field: Identifies the corresponding line feature in result data.
• Extraction Interval: Sets the interval for extracting scale values. If set to 100, values will be extracted at 100-unit intervals from the starting route value (e.g., 0, 100, 200). Note: No extraction occurs if the difference between the termination route value and previous scale value is smaller than the interval.
• Result Data: Specifies the datasource and name for storing the result dataset. The output is a point dataset containing route scale values.
• The attribute table of the result dataset retains the Route ID Field from source data, and adds new fields: Scale (route value) and Angle (label orientation). Configure symbology using these fields to display route values as shown:
