datacube.utils.geometry.CRS¶

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

Wrapper around pyproj.CRS for backwards compatibility.

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

__init__(crs_str)[source]¶

Methods

`__init__`(crs_str)
`to_epsg`()	Return EPSG Code of the CRS or None.
`to_wkt`([pretty, version])	WKT representation of the CRS
`transformer_to_crs`(other[, always_xy])	Return a function that maps x, y -> x’, y’.

Attributes

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

Attributes:

`crs_str`	DEPRECATED
`dimensions`	List 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`()	Return EPSG Code of the CRS or None.
`to_wkt`([pretty, version])	WKT representation of the CRS
`transformer_to_crs`(other[, always_xy])	Return a function that maps x, y -> x’, y’.

property crs_str: str¶

DEPRECATED

Return type: str

property dimensions: Tuple[str, str]¶

List 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]¶

Return 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]¶

Return 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.

Return type: Optional[Geometry]
Returns: Bounding box in Lon/Lat as a 4 point Polygon in EPSG:4326 or None if not defined
