Function:

This activity allows you to perform linear referencing to extract line features.

In a Workflow:

You would use this activity to obtain a portion of a line feature based on start and end index values. For example: extract the portion of a pipeline from Kilometer marker 2.0 to Kilometer marker 3.5.

Properties:

Name	Description
In Arguments
Line	The length indexed line to extract the line from.
Start Index	The start point index of the desired starting point along the line (the distance along the line).
End Index	The index of the desired end point along the line (the distance along the line). If the EndIndex lies before the StartIndex, the computed geometry is reversed.
Misc
Display Name	ExtractLine You can change the name of an activity to one that describes what it does. A descriptive name can make a workflow easier to interpret and maintain.
Out Arguments
Result	The calculated portion of the line between the specified indices.
