The easiest is probably the CoordinateExtractor - use 0 for the first vertex, and -1 for the last. If you want them as points, add a VertexCreator as well. You may have problems if the direction of digitising isn't standardised!

I see where to choose what X/Y coordinates to use for the point but this doesn't seem to add a attribute as the point with those coordinates. Am i missing something or doing something wrong. The reason I am doing this is I have a line segment and the database I am saving it to only has start and end point locations. So nothing for the actual segment. I did like you said used a extractor to get my start/end point x/y coordinates. Now I need to create a attribute that stores them as a coordinate (X:Y)

If you need to create a string like "(x:y)" from a pair of x and y, just use the AttributeCreator or the StringConcatenator.

If you wanted to get point features, the often-overlooked "Snipper" transformer can easily get the First and Last points of a line -- just set it to "Vertex" mode and use 0 for the indexes when you want to get the first point, and -1 when you want to get the last point. See attached workspace.

 

 

However, your comment after @rollo's answer makes me think you don't want geometry for your first and last points, but rather you want attributes. In that case the CoordinateExtractor is the way to go -- use two of them back to back to get the first / last points, be careful what you name them, then use an attribute creator potentially (or a StringConcatenator) to glue the values together if that is what you need done. CHeck out http://docs.safe.com/fme/html/FME_Transformers/FME_Transformers.htm#Transformers/stringconcatenator.htm for descriptions of how to get into the "string editor" to do this type of thing.

Is it addressed?

@DateAtSafe This is a start but how do I reference the endpoints to run a neighborfinder & add related info from the neighbor? I have a Linear_Structure & I need to get info from Point_Structure at each end vertex & then place them in corresponding field (i.e., Start_Pt_Struct_ID & End_Pt_Struct_ID?

Hi @danpressler

 

I would recommend creating a new forum Q&A; post for greater visibility. You can link to this post and also provide more context regarding your workflow in the new post. Would you be able to do that?

@sabine​ I've attached an example workspace (FME 2020.2). It has three options you can use, depending on what output you need. Since this article was created someone has created a custom transformer on the FME HUB to do this (Extract_End_Points) which is probably what you need.
