+17Looks a bit like the MeasureInterpolator that is in the FME Store. But that does not extrapolate if the first or last point has no measure. I have been looking for this functionality before. So, Yes I would like this too!
Actually, my suggestion is rather different, as the MeasureInterpolator already assumes that your line has some measures to begin with. My suggestion would take a point and a line dataset and snap them together (using Tolerance and Group By) to assign measures, then interpolate any missing values.
I think ESRI's MakeRouteEventLayer is so simple to call from Python. We can LRS either points or lines from the route linear network which has M values.
Something along those lines would be a no-brainer.
Would absolutely love this idea to be implemented as well all in a single transformer to avoid highly complex manipulations.
It would be very similar to ESRI's Calibrate Routes tool which interpolate measures based on an existing set of points that do not necessarily fall on the line.
I'm unable to get this workflow replicated in FME.
