Concentric rings

Concentric rings radiating out of a point.

Concentric rings are a series of rings, each of a larger diameter, that radiate out of the same point or feature. Concentric objects share the same center, axis, or origin with one inside the other. In ESRI ArcMap products concentric rings, or buffers, can be created using the Multiple Ring Buffer tool.

Uses for Concentric Rings

Concentric rings are useful in the analysis of multiple problems. They are used many times to judge the effects of a phenomenon on the surrounding areas. Concentric rings provide a quick means of determining and categorizing the surrounding areas of a point or feature. They are utilized in hazard analysis, disease spread, areas of concern, and many other spatial problems.
