Which transformer would you use to combine several lines into a single geometry object containing them all?

• A. Aggregator
• B. Bufferer
• C. Clipper
• D. Dissolver

Answer: (D)

Dissolving geometries merges multiple features into one by removing the internal boundaries that belong together. To combine several lines into a single geometry object, give all the lines the same dissolve key (or use a constant value) and run the Dissolver. This treats them as one group and outputs a single feature whose geometry contains all the input lines.

Other transformers don’t merge geometries in this way. Aggregator focuses on combining attributes or collecting features, not unifying their shapes. Bufferer creates new geometry around each line, increasing size but keeping them separate. Clipper cuts features with another geometry, not merging the inputs into one object.
