LineOnLineOverlayer, events and LRS

Extract points at measures (for instance snipper). Create id for point.

Duplicate and add serialnumber.

Get angle of line at pointlocation.

Ofsetter to offset sufficiently (to intersect border of polygon) using angle (+ and - 90 degrees).

Pointconnector to create line out of the points. (group by point_id)

LineOnArea overlayer and tester to get line piece.

Get its length.

Ah, ok i thought u needed width of polygon fo the tapered buffer at measure.

I did build an example.

You want length of line between the measures (word "width"confused me there..)

OK.

Use measure extractor. Use list.

Explode the list.

Create a attribute with adjacent feature. Create a attribute "measure_to" = feature[+1]._measures

Use a snipper on the lines, mode=distance. Start = measure End = measure_to.

Lenghtcalculator on the result.

addendum

you can also use snipper in measure mode (relative to startpoint) and then enter the list name from the measure extractor if your measures have mulitplier >1 (my posted fmwt i created them by densifying the polyline and created measure with the multiplier=1)

come to think of it,..maybe I'm misinterpreting the question..?

Just an overlay of the lines with measures?

thanks a lot.

I did not explained it correctly.

I already have extracted the measure. I want just to have the change in the amount of buffer (because I want to use Taperbuffer). Lets say I want to have 2 attributes : one for start and one for end of line (because I'm using the LineOnlineoverlayer then the start and end change at every new measure).

thanks again
