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)	param crs_str string representation of a CRS, often an EPSG code like 'EPSG:4326'
`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

Return type: str

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.

Return type: Tuple[str, str]

property proj: pyproj.crs.crs.CRS#

Access proj.CRS object that this wraps

Return type: CRS

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.

Return type: Tuple[str, str]

property valid_region: Optional[datacube.utils.geometry._base.Geometry]#

Return valid region of this CRS.

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

Return type: Optional[Geometry]
