Hi Steve,
Took a little more work than I expected, but one way to go is the
TopologyBuilder. This creates an ID for each node (stop) and applies
it to the link (route). Then it's just a case of grabbing the stop ID
using the node ID as a join attribute in a FeatureMerger.
Note that a list is created in each FeatureMerger and the first entry
in that list has been manually exposed (right-clicked list1{}.stopID
and exposed one element to give list1{0}.stopID which is later renamed
to _stop_from)
I took the liberty of adding this as an example on fmepedia - you can
find it at...
http://www.fmepedia.com/index.php/TopologyBuilder_Example
Hope this helps. The workspace generates simple test data - you'll
just need to plug in your own data (and rename a few of the attributes
in the transformers).
Regards,
Mark
