A domain ancillary construct of the CF data model.
A domain ancillary construct provides information which is needed for computing the location of cells in an alternative coordinate system. It is referenced by a term of a coordinate conversion formula of a coordinate reference construct. It contains a data array which depends on zero or more of the domain axes.
It also contains an optional array of cell bounds, stored in a
Bounds
object, recording the extents of each cell (only applicable if the array contains coordinate data), and properties to describe the data.An array of cell bounds spans the same domain axes as the data array, with the addition of an extra dimension whose size is that of the number of vertices of each cell.
New in version 1.7.0.
Initialization
- Parameters
- properties:
dict
, optional Set descriptive properties. The dictionary keys are property names, with corresponding values. Ignored if the source parameter is set.
Properties may also be set after initialisation with the
set_properties
andset_property
methods.- Parameter example:
properties={'standard_name': 'longitude'}
- data:
Data
, optional Set the data array. Ignored if the source parameter is set.
The data array may also be set after initialisation with the
set_data
method.- bounds:
Bounds
, optional Set the bounds array. Ignored if the source parameter is set.
The bounds array may also be set after initialisation with the
set_bounds
method.- geometry:
str
, optional Set the geometry type. Ignored if the source parameter is set.
The geometry type may also be set after initialisation with the
set_geometry
method.- Parameter example:
geometry='polygon'
- interior_ring:
InteriorRing
, optional Set the interior ring variable. Ignored if the source parameter is set.
The interior ring variable may also be set after initialisation with the
set_interior_ring
method.- source: optional
Initialize the properties, geometry type, data, bounds and interior ring from those of source.
- copy:
bool
, optional If False then do not deep copy input parameters prior to initialization. By default arguments are deep copied.
- properties:
