Which transformer would you use to combine multiple polygons separated by secondary soil types into fewer larger polygons grouped by their shared primary soil type?

Which transformer would you use to combine multiple polygons separated by secondary soil types into fewer larger polygons grouped by their shared primary soil type?

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

Answer: (C)

Dissolving is about merging adjacent polygons that share a common value, removing the internal boundaries between them. When you set the dissolve attribute to the primary soil type, every polygon that has the same primary soil type will be merged with its neighbors, creating larger polygons that represent each primary soil type. The secondary soil types no longer force separate features because the boundaries are dissolved within those primary-type groups. The other options don’t fit: Aggregator groups features and can summarize attributes but doesn’t automatically merge the geometries into a single polygon per group; Clipper cuts polygons along boundaries; Bufferer adds a surrounding zone. So the Dissolver is the right choice.
