How do ring buffers work?
Circular buffers (also known as ring buffers) are fixed-size buffers that work as if the memory is contiguous & circular in nature. As memory is generated and consumed, data does not need to be reshuffled – rather, the head/tail pointers are adjusted. When data is added, the head pointer advances.
How do I add a radius in Arcmap?

- Use the cursor to select the size of the circle and click to draw the circle.
What does it mean to have multiple ring buffers?
ALL —Buffers will be rings around the input features that do not overlap (think of these as rings or donuts around the input features).
How to dissolve multiple ring buffers in ArcGIS?
If the Dissolve Option ALL is used, the output feature class will contain one feature for each distance specified in the Distances parameter (all buffers the same distance from the Input Features will be dissolved). The tool creates intermediate data which is written to the location specified in the Scratch_workspace environment setting.
How to create a handle for a circular buffer?
We will create a handle type that they can use instead. The simplest approach for our handle is to typedef the cbuf_handle_t as a pointer to the circular buffer. This will prevent us from needing to cast the pointer within our function implementation. An alternative approach would be to make the handle a uintptr_t or void* value.
How to use multiple ring buffer in Python?
OUTSIDE_ONLY —Buffers will be rings around the input features, and will not overlap or cover the input features (the area inside the input polygon will be erased from the buffer). The following Python window script demonstrates how to use the MultipleRingBuffer tool in immediate mode.
