Dissolve Route Events (Linear Referencing)

ArcGIS Pro 3.4 | | Help archive

Summary

Removes redundant information from event tables or separates event tables having more than one descriptive attribute into individual tables.

Usage

  • The input table can be any type of table that ArcGIS supports. The output table can be a .dbf file or a geodatabase table.

  • If the Input Event Table parameter value does not have an ObjectID field, use the Make Query Table tool before using this tool to add a virtual ObjectID field.

  • An attribute index on the route identifier field speeds up the dynamic segmentation process. If you will be using the Output Event Table parameter value for dynamic segmentation, it is recommended that you create an attribute index.

Parameters

LabelExplanationData Type
Input Event Table

The table with the rows that will be aggregated.

Table View
Event Table Properties

The route location fields and the type of events in the input event table.

  • Route Identifier Field—The field containing values that indicate the route on which each event is located. This field can be a numeric, text, or GUID field.
  • Event Type—The type of events in the input event table (Point or Line).
    • Point—Point events occur at a precise location along a route. Only a from-measure field must be specified.
    • Line—Line events define a portion of a route. Both from- and to-measure fields must be specified.
  • From-Measure Field—A field containing measure values. This field must be numeric and is required when the event type is Point or Line. When the Event Type value is Point, the label for this parameter becomes Measure Field.
  • To-Measure Field—A field containing measure values. This field must be numeric and is required when the event type is Line.

Output Event Table

The table that will be created.

Table
Output Event Table Properties

The route location fields and the type of events that will be written to the output event table.

  • Route Identifier Field—The field that will contain values that indicate the route on which each event is located. The field can be a numeric, text, or GUID field.
  • Event Type—The type of events the output event table will contain (Point or Line).
    • Point—Point events occur at a precise location along a route. Only a single measure field must be specified.
    • Line—Line events define a portion of a route. Both from- and to-measure fields must be specified.
  • From-Measure Field—A field that will contain measure values. This field is required when the event type is Point or Line. When the Event Type value is Point, the label for this parameter becomes Measure Field.
  • To-Measure Field—A field that will contain measure values. This field is required when the event type is Line.
Route Measure Event Properties
Combine adjacent events only
(Optional)

Specifies how the input events will be aggregated.

  • Unchecked—Events will be aggregated wherever there is measure overlap. This is the default.
  • Checked—Events will be aggregated where the to-measure of one event matches the from-measure of the next event. This option is applicable only for line events.
Boolean
Build index
(Optional)

Specifies whether an attribute index will be created for the route identifier field that is written to the output event table.

  • Checked—An attribute index will be created. This is the default.
  • Unchecked—An attribute index will not be created.
Boolean
