I have irregular line segments that I need to create points along using station (M) values.

The actual Shape Length of the line and the station values are not the same (i.e. shape length of 50 and end M value of 75).

The line feature has the M values as a property, but not as an attribute.

The beginning and end M values for the line segments are known.

Is there a way to reassign line length (in memory) based on the known M values so that I can place (snip) points on interpolated values along the line?

Thanks in advance,

Freddy

Hi @fneal, if the 'M' indicates the measure of a node of the line segment, the Snipper transformer with "Measure (Value)" mode might help you. For example, assume the measure values of start and end nodes are 0 and 15, the Snipper with this parameters setting outputs a point having measure of 5, regardless of the length of the line.

  • Snipping Mode: Measure (Value)
  • Starting Location: 5
  • Ending Location: 5
Why not inspect features with Visual/Data Preview and Feature/Record Information before writing them into a destination dataset?

This worked perfectly. Thanks very much!
