# xarray.core.coordinates.DatasetCoordinates.merge¶

DatasetCoordinates.merge(other)

Merge two sets of coordinates to create a new Dataset

The method implements the logic used for joining coordinates in the result of a binary operation performed on xarray objects:

• If two index coordinates conflict (are not equal), an exception is raised. You must align your data before passing it to this method.

• If an index coordinate and a non-index coordinate conflict, the non- index coordinate is dropped.

• If two non-index coordinates conflict, both are dropped.

Parameters

other (DatasetCoordinates or DataArrayCoordinates) – The coordinates from another dataset or data array.

Returns

merged – A new Dataset with merged coordinates.

Return type

Dataset
