I have duplicate line segments with same unique ID but different lengths. I would like to filter out the shorter line and keep the longer line for further transformation.
Solved
Compare and filter out line with shorter length
Best answer by jdh
Calculate the length, sort your features by length and then use a sampler (First 1 feature), grouped on the Unique ID attribute. The longest lines will be from the sampled port, and the shorter duplicate lines will be sent through the unsampled port.
Alternately use a DuplicateRemover in place of the Sampler.

If you sort by unique ID and length in desc order then use a duplicate remover, FME will output the longer line via the unique port.
