# 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
