xugrid.UgridDataArrayAccessor

class xugrid.UgridDataArrayAccessor(obj: DataArray, grid: Type[AbstractUgrid])

This “accessor” makes operations using the UGRID topology available via the .ugrid attribute for UgridDataArrays and UgridDatasets.

__init__(obj: DataArray, grid: Type[AbstractUgrid])

Methods

__init__(obj, grid)
assign_edge_coords()	Assign edge coordinates from the grid to the object.
assign_face_coords()	Assign face coordinates from the grid to the object.
assign_node_coords()	Assign node coordinates from the grid to the object.
binary_dilation([iterations, mask, border_value])	Binary dilation can be used on a boolean array to expand the "shape" of features.
binary_erosion([iterations, mask, border_value])	Binary erosion can be used on a boolean array to shrink the "shape" of features.
clip_box(xmin, ymin, xmax, ymax)	Clip the DataArray or Dataset by a bounding box.
connected_components()	Every edge or face is given a component number.
interpolate_na([method, max_distance])	Fill in NaNs by interpolating.
intersect_line(start, end)	Intersect a line with the grid of this data, and fetch the values of the intersected faces.
intersect_linestring(linestring)	Intersect the grid along a collection of linestrings.
laplace_interpolate([xy_weights, ...])	Fill in NaNs by using Laplace interpolation.
partition(n_part)	Partition a grid into a given number of parts.
partition_by_label(labels)	Partition a grid by labels.
rasterize(resolution)	Rasterize unstructured grid by sampling.
rasterize_like(other)	Rasterize unstructured grid by sampling on the x and y coordinates of other.
reindex_like(other[, tolerance])	Conform this object to match the topology of another object.
rename(name)	Give a new name to the UGRID topology and update the associated coordinate and dimension names in the DataArray.
reverse_cuthill_mckee()	Reduces bandwith of the connectivity matrix.
sel([x, y])	Return a new object, a subselection in the UGRID x and y coordinates.
sel_points(x, y[, out_of_bounds, fill_value])	Select points in the unstructured grid.
set_crs([crs, epsg, allow_override])	Set the Coordinate Reference System (CRS) of a UGRID topology.
set_node_coords(node_x, node_y)	Given names of x and y coordinates of the nodes of an object, set them as the coordinates in the grid.
to_crs([crs, epsg])	Transform geometries to a new coordinate reference system.
to_dataset([optional_attributes])	Convert this UgridDataArray or UgridDataset into a standard xarray.Dataset.
to_geodataframe([name, dim_order])	Convert data and topology of one facet (node, edge, face) of the grid to a geopandas GeoDataFrame.
to_netcdf(*args, **kwargs)	Write dataset contents to a UGRID compliant netCDF file.
to_nonperiodic(xmax)	Convert this grid from a periodic grid (where the rightmost boundary shares its nodes with the leftmost boundary) to an aperiodic grid, where the leftmost nodes are separate from the rightmost nodes.
to_periodic()	Convert this grid to a periodic grid, where the rightmost boundary shares its nodes with the leftmost boundary.
to_zarr(*args, **kwargs)	Write dataset contents to a UGRID compliant Zarr file.
