# Raster Profile
|
|
|
|
Extract pixel values along a line or path.
|
|
|
|
## Overview
|
|
|
|
Raster profile extracts pixel values from a raster dataset along a specified line or path.
|
|
|
|
## Inputs
|
|
|
|
- **Raster Dataset**: Raster dataset to sample
|
|
- **Line Geometry**: GeoJSON LineString for profile path
|
|
- **Band** (optional): Band to sample (default: first band)
|
|
|
|
## Outputs
|
|
|
|
Profile data containing:
|
|
|
|
- Distance along line
|
|
- Pixel values at each point
|
|
- Coordinates
|
|
|
|
## Example
|
|
|
|
```json
|
|
{
|
|
"raster_dataset_id": 125,
|
|
"line_geometry": {
|
|
"type": "LineString",
|
|
"coordinates": [ ... ]
|
|
}
|
|
}
|
|
```
|
|
|
|
## Use Cases
|
|
|
|
- Elevation profiles
|
|
- Transect analysis
|
|
- Cross-section extraction
|
|
- Value sampling
|
|
|
|
## Notes
|
|
|
|
- Line geometry defines sampling path
|
|
- Values interpolated for sub-pixel positions
|
|
- Results include distance and values
|
|
- Processing time depends on line length
