list_authority

Equi7Grid_projection.list_authority(auth_name: str | None = None, min_confidence: int = 70) list[AuthorityMatchInfo]

New in version 3.2.0.

Return the authority names and codes best matching the CRS.

Example:

>>> from pyproj import CRS
>>> ccs = CRS("EPSG:4328")
>>> ccs.list_authority()
[AuthorityMatchInfo(auth_name='EPSG', code='4326', confidence=100)]

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.list_authority()
[]
>>> ccs.source_crs.list_authority()
[AuthorityMatchInfo(auth_name='EPSG', code='4978', confidence=70)]
>>> 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:
