# Erase Analysis
|
|
|
|
Remove portions of features from an input dataset that overlap with an erase dataset.
|
|
|
|
## Overview
|
|
|
|
Erase analysis removes portions of input features that overlap with erase features, creating new geometries.
|
|
|
|
## Inputs
|
|
|
|
- **Input Dataset**: Dataset to erase from
|
|
- **Erase Dataset**: Dataset to erase with
|
|
|
|
## Outputs
|
|
|
|
New dataset containing:
|
|
|
|
- Features with erased portions removed
|
|
- Remaining geometry after erase
|
|
- Original attributes preserved
|
|
|
|
## Example
|
|
|
|
```json
|
|
{
|
|
"input_dataset_id": 123,
|
|
"erase_dataset_id": 124
|
|
}
|
|
```
|

|
## Background Jobs
|
|
|
|
This analysis runs as a background job. See [Erase Analysis Worker](../workers/erase_analysis.md) for details.
|
|
|
|
## Use Cases
|
|
|
|
- Exclusion zone mapping
|
|
- Feature subtraction
|
|
- Boundary modification
|
|
- Area calculations
|
|
|
|
## Notes
|
|
|
|
- Overlapping portions are removed
|
|
- Non-overlapping features preserved
|
|
- Complex geometries may slow processing
|
|
- Results depend on overlap extent
