class eoforeststac.providers.align.DatasetAligner(*, target: str | None = None, crs: str | None = None, resolution: float | Tuple[float, float] | None = None, resampling: str | Mapping[str, str | Mapping[str, str]] = 'nearest', snap_resolution: str = 'auto', snap_tolerance: float = 1e-06, coarsen_factor: int = 1, coarsen_agg: str | Mapping[str, str] = 'auto', canonical_spatial_dims: Tuple[str, str] = ('longitude', 'latitude'))

Align multiple xarray Datasets onto a common spatial grid.

Features

• GridSpec contract (CRS + transform + shape + hash)

• Automatic resolution snapping (optional)

• Per-dataset and per-variable resampling overrides

• Optional coarsening before reprojection (fast-downsample)

• Strict merge semantics
