stackstac.array_bounds#

stackstac.array_bounds(arr, to_epsg=None)#

Get the bounds of a DataArray.

The bounds are either taken from the spec attribute, or computed from the x and y coordinates.

Parameters:

  • arr (DataArray) –

    The DataArray must either have a RasterSpec as the spec attribute (preferred), or the coordinates x and y.

    The x and y coordinates are assumed to indicate the top-left corner of each pixel, not the center. They’re also assumed to be evenly spaced (constant resolution), and must be monotonic.

  • to_epsg (Optional[int]) – CRS to reproject the bounds to, as an EPSG code. If None (default), the bounds are not reprojected. If not None, the DataArray must have an epsg coordinate.

Returns:

Bounds of the DataArray, as a 4-tuple.

Return type:

Bbox

Raises:

  • ValueError: – If the DataArray has no spec attribute.

  • ValueError: – If the DataArray is missing the x or y coordinates.

  • ValueError: – If x or y coordinates are not monotonic.

  • ValueError: – If to_epsg is given, and the CRS of the ~xarray.DataArray cannot be determined by array_epsg.
