xugrid.UgridRolesAccessor

class xugrid.UgridRolesAccessor(ds: Dataset)

Xarray Dataset “accessor” to retrieve the names of UGRID variables.

Examples

To get a list of the UGRID dummy variables in the dataset:

>>> dataset.ugrid_roles.topology

To get the names of the connectivity variables in the dataset:

>>> dataset.ugrid_roles.connectivity

Names can also be accessed directly through the topology:

>>> dataset.ugrid_roles["mesh2d"]["node_dimension"]

__init__(ds: Dataset)

Methods

__init__(ds)

Attributes

connectivity	Get the names of the variables containing the UGRID connectivity data.
coordinates	Get the names of the coordinate variables from the topology attributes.
dimensions	Get the dimension names from the topology attributes and infer them from connectivity arrays or coordinates.
grid_mapping_names	Get the names of the grid mapping variables associated with each topology.
is_projected	Infer whether each topology uses projected or geographic coordinates from the standard_name attributes of the coordinate variables.
topology	Get the names of the topology dummy variables, marked by a CF-role of mesh_topology.
