Which transformer is best suited for creating buffer zones around features?

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

Answer: (A)

Bufferer creates buffer zones around features. It expands each input feature outward by a specified distance, producing a new polygon that represents the zone around the original geometry. This makes it the ideal tool for proximity analyses, such as defining safety or influence areas around roads, rivers, or points. The other transformers don’t generate such outward zones: Clipper trims features to a clipping boundary, Aggregator groups or merges features by attributes, and Dissolver merges adjacent polygons.
