# Buffer Analysis

Create buffer zones around features at specified distances.

## Overview

Buffer analysis creates zones around features at specified distances, useful for proximity analysis and impact assessment.

## Inputs

- **Dataset**: Any vector dataset
- **Distance**: Buffer distance in dataset units
- **End Cap Style**: Round or flat
- **Dissolve**: Merge overlapping buffers

## Outputs

New polygon dataset containing:

- Buffer zones around input features
- Original feature attributes
- Buffer distance information

## Example

```json
{
  "dataset_id": 123,
  "distance": 1000,
  "dissolve": false
}
```

## Use Cases

- Service area analysis
- Impact zone identification
- Proximity analysis
- Safety zone mapping

## Notes

- Distance units match dataset SRID
- Dissolving reduces output complexity
- Multiple distances can be applied
- Buffers around lines create polygons
