Create new line from measure


Forum|alt.badge.img

Hi,

I have polyline with polyline_id with start and end measure (ex : 0 and 100). And another descriptive information (without geometry) with start and end measure (ex. 50 and 75) and the polyline_id.

I did featureMerger and then snipper with measure value.

But I got the whole polyline (0 start and 100 end ) but I want polyline with (50 and 75)

There is something wrong. Any idea how can I get it.

Thanks

I think you have the right approach.

The image shows the Snipper approach:

The result is a line from measure 25 to 75.

thanks, it is only working with distance value (but I'm not sure if one can use distance value to get lines from measure to measure). If I use measure value I got the whole polylines.

IN my example I used the Snipper, using Measure (value).

 

I have attached the sample workspace.

thanks. It was strange. If I use the polylines from gdb, then measure setter or generator is working. If I use Postgis source, it does not.
