to_authority

Equi7Grid_projection.to_authority(auth_name: str | None = None, min_confidence: int = 70)

New in version 2.2.0.

Return the authority name and code best matching the CRS or None if it a match is not found.

Example:

>>> from pyproj import CRS
>>> ccs = CRS("EPSG:4328")
>>> ccs.to_authority()
('EPSG', '4328')

If the CRS is bound, you can get an authority from the source CRS:

>>> from pyproj import CRS
>>> ccs = CRS("+proj=geocent +datum=WGS84 +towgs84=0,0,0")
>>> ccs.to_authority()
>>> ccs.source_crs.to_authority()
('EPSG', '4978')
>>> ccs == CRS.from_authorty('EPSG', '4978')
False

Parameters:

auth_name (str, optional) – The name of the authority to filter by.
min_confidence (int, default=70) – A value between 0-100 where 100 is the most confident. min_confidence

Returns:

The best matching (<auth_name>, <code>) for the confidence level.

Return type:

tuple(str, str) or None
