# Skill: Raster Pipeline

Use this skill for GeoTIFF/raster metadata, clipping, tiling, band handling and remote-sensing indices.

## Read first

- `docs/RASTER_OPERATIONS_SPEC.md`
- `docs/standards/RASTER_STANDARDS.md`
- `docs/DETECTION_PIPELINE_SPEC.md` when preparing AI tiles
- `docs/STORAGE_ARCHITECTURE.md`

## Raster rules

- Preserve georeferencing metadata.
- Never drop CRS silently.
- Keep raster-derived outputs traceable to source dataset and parameters.
- Use deterministic tile naming.
- Store heavy outputs under documented storage roots, not random folders.
- For V1, prefer metadata and small fixtures over heavy real rasters.

## Operations checklist

- [ ] Validate raster readable.
- [ ] Extract CRS, bounds, transform, dimensions, band count, dtype.
- [ ] Clip by area where requested.
- [ ] Generate tiles with configured tile size and overlap.
- [ ] Preserve mapping from tile pixels to map coordinates.
- [ ] Emit metadata JSON for downstream services.
- [ ] Add tests with tiny raster fixtures when possible.
