podpac.coordinates.ArrayCoordinates1d¶

class podpac.coordinates.ArrayCoordinates1d(coordinates, name=None, **kwargs)[source]¶

Bases: podpac.core.coordinates.coordinates1d.Coordinates1d

1-dimensional array of coordinates.

ArrayCoordinates1d is a basic array of 1d coordinates created from an array of coordinate values. Numerical coordinates values are converted to float, and time coordinate values are converted to numpy datetime64. For convenience, podpac automatically converts datetime strings such as '2018-01-01' to datetime64. The coordinate values must all be of the same type.

Parameters

name (str) – Dimension name, one of ‘lat’, ‘lon’, ‘time’, or ‘alt’.
coordinates (array, read-only) – Full array of coordinate values.

Members

__init__(coordinates, name=None, **kwargs)[source]¶

Create 1d coordinates from an array.

Parameters

coordinates (array-like) – coordinate values.
name (str, optional) – Dimension name, one of ‘lat’, ‘lon’, ‘time’, or ‘alt’.

property argbounds¶

property bounds¶: Low and high coordinate bounds.

coordinates¶: A coercing numpy array trait.

copy()[source]¶

Make a deep copy of the 1d Coordinates array.

Returns: Copy of the coordinates.
Return type: ArrayCoordinates1d

property dtype¶

Coordinates dtype.

float for numerical coordinates and numpy datetime64 for datetime coordinates.

Type: type

flatten()[source]¶

Get a copy of the coordinates with a flattened array (wraps numpy.flatten).

Returns: Flattened coordinates.
Return type: ArrayCoordinates1d

classmethod from_definition(d)[source]¶

Create 1d coordinates from a coordinates definition.

The definition must contain the coordinate values:

c = ArrayCoordinates1d.from_definition({
    "values": [0, 1, 2, 3]
})

The definition may also contain any of the 1d Coordinates properties:

c = ArrayCoordinates1d.from_definition({
    "values": [0, 1, 2, 3],
    "name": "lat"
})

Parameters: d (dict) – 1d coordinates array definition
Returns: 1d Coordinates
Return type: ArrayCoordinates1d
