May I know that how to export each vertex from a geometry?
I tried to use Vertex Creator before, but the output is not one record for one point, but one record for all points.
For example, there is a polygon with 4 vertex,
The result I want to get like this:
Pointxy1xxxxxxxxxxxx2xxxxxxxxxxxx3xxxxxxxxxxxx4xxxxxxxxxxxx
but not like this:
Polygonx1y1x2y2x3y3x4y41xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxIs there any function can help me solve this case?
Thank you.
Coordinate extractor extracting all coordinates followed by a list exploder. Note that vertex numbers start from 0 not 1
I would use the CoordinateConcatenator first (to create a concatenated list, using comma as ordinate and semi-colon as vertex seperator).
Then use the AttributeSplitter to create a list (splitting on semi-colon).
The ListExploder will give you a feature per list item (these will be the points).
The second AttributeSplitter (split on comma) will give you the X and Y coordinates as attributes.
That is a lot of typing.
An easier way:
Use the Chopper to create vertices.
Use the CoordinateExtractor to extract X and Y to attributes.
Should have thought of this one first.
or simply Chopper by Maximum vertices =1.
Another method is to use the FME Objects Python API: https://docs.safe.com/fme/html/FME_Objects_Python_API/index.html. I would recommend to use this option if you're familiar with Python.
Within the class FMEPolygon you can use the inherited function bounds() which returns a tuple of FMEPoint objects. Next you can loop over this tuple and return each point. Finally remove duplicate points if necessary.

As I can proceed CoordinateConcatenator and get the result of
BuildingIDCoordinate 1xxxxxx , xxxxxx , xxxxxx ; xxxxxx , xxxxxx , xxxxxx ;........

Setting it to 1 on the Maximum Vertices will result in point features, setting it to two will reslut in lines with maximal 2 vertices etc, etc see the help for more detailed information about the transformer.
If you need the X/Y values you can use the CoordinateExtractor after the Chopper, as mentioned below.

If you need to add index attribute to the output features, consider using a Counter additionally. Or, the VertexExtractor (from Hub) might help you.
