xoa.grid.to_rect

xoa.grid.to_rect(da, tol=1e-05, errors='warn')

Convert the curvilinear coordinates of array/dataset to rectangular axis coordinates

It checks if the coordinates may be converted to 1D axis without loss of information.

Parameters:

• da (xarray.DataArray, xarray.Dataset) – In case of a dataset, it must contain longitudes and latitudes.

• to (float) – Absolute tolerance of the variability of a coordinate along its constant dimension to consider it as a 1D axis coordinate.

• errors ({'ignore', 'warn', 'raise'}) –

  In case of errors

  • 'ignore': silently ignore

  • 'warn': emit a warning

  • 'raise': raise an exception

Returns:

xarray.DataArray, xarray.Dataset
