datacube.utils.geometry.CRS¶

class datacube.utils.geometry.CRS(crs_spec)[source]¶

Wrapper around pyproj.CRS for backwards compatibility.

Parameters:: crs_str – string representation of a CRS, often an EPSG code like ‘EPSG:4326’
Raises:: pyproj.exceptions.CRSError

__init__(crs_spec)[source]¶

Parameters:: crs_str – string representation of a CRS, often an EPSG code like ‘EPSG:4326’
Raises:: pyproj.exceptions.CRSError

Methods

`__init__`(crs_spec)
`to_epsg`()	EPSG Code of the CRS or None
`to_wkt`([pretty, version])	WKT representation of the CRS
`transformer_to_crs`(other[, always_xy])	Returns a function that maps x, y -> x', y' where x, y are coordinates in this stored either as scalars or ndarray objects and x', y' are the same points in the other CRS.

Attributes

`DEFAULT_WKT_VERSION`
`crs_str`	DEPRECATED
`dimensions`	List of dimension names of the CRS.
`epsg`
`geographic`
`inverse_flattening`
`proj`	Access proj.CRS object that this wraps
`projected`
`semi_major_axis`
`semi_minor_axis`
`units`	List of dimension units of the CRS.
`valid_region`	Return valid region of this CRS.
`wkt`

Attributes:

`crs_str`	DEPRECATED
`dimensions`	List of dimension names of the CRS.
`proj`	Access proj.CRS object that this wraps
`units`	List of dimension units of the CRS.
`valid_region`	Return valid region of this CRS.

Methods:

`to_epsg`()	EPSG Code of the CRS or None
`to_wkt`([pretty, version])	WKT representation of the CRS
`transformer_to_crs`(other[, always_xy])	Returns a function that maps x, y -> x', y' where x, y are coordinates in this stored either as scalars or ndarray objects and x', y' are the same points in the other CRS.

property crs_str: str¶: DEPRECATED

property dimensions: Tuple[str, str]¶: List of dimension names of the CRS. The ordering of the names is intended to reflect the numpy array axis order of the loaded raster.

property proj: CRS¶: Access proj.CRS object that this wraps

to_epsg()[source]¶

EPSG Code of the CRS or None

Return type:: Optional[int]

to_wkt(pretty=False, version=None)[source]¶

WKT representation of the CRS

Return type:: str

transformer_to_crs(other, always_xy=True)[source]¶

Returns a function that maps x, y -> x’, y’ where x, y are coordinates in this stored either as scalars or ndarray objects and x’, y’ are the same points in the other CRS.

Return type:: Callable[[Any, Any], Tuple[Any, Any]]

property units: Tuple[str, str]¶: List of dimension units of the CRS. The ordering of the units is intended to reflect the numpy array axis order of the loaded raster.

property valid_region: Geometry | None¶

Return valid region of this CRS.

Bounding box in Lon/Lat as a 4 point Polygon in EPSG:4326. None if not defined
