Hello everybody!
I just wanna solve problem with Z values (as stand alone entity), which I want to merge with attributes of line feature. My problem is following (please check the picture below):
As You can see, there is text point with Z value, but their def point is totally out of vertex of line feature. What I need is to get line feature with 2 attributes - Z value of start vertex and Z value of end vertex. Is anybody here, who has solution of this situation please?
Thank You so much!
Lubo

Not precisely sure what you need to do, but you can retrieve the start (or end) coordinate via the CoordinateExtractor. An index of 0 gets you the first coordinate, and -1 will get you the second one. So putting down 2 of these transformers and choosing appropriate names and indexes and running through them in series (one after the other) will result in you having your start and end Z values as attributes on your line features.

the next step can be using the xy coordinates of the start and end to create point features and feeding them to the neighborfinder along with the text nodes.
When set correctly the neighbourfinder will result in a list of all the features within the specified distance tolerance.
So analyzing the list elements and for example retrieving the nearest text node might be what you are searching for.
Good luck !

then just use the lines and not start and end points in the analysis

Maybe supply us a small sample and we can give a careful look. I suspect it may take clever use of neighbourfinder (maybe 2 of them) so you can get the z values from the text nodes onto the end points of the line.
