xarray.DataArray.xvec.is_geom_variable

DataArray.xvec.is_geom_variable(name, has_index=True)

Check if coordinate variable is composed of shapely.Geometry.

Can return all such variables or only those using GeometryIndex.

Parameters:

namecoordinate variable name

has_indexbool, optional

control if all variables are returned (False) or only those that have xvec.GeometryIndex assigned (True). By default False

Returns:

bool
