Method Details

__init__(self, latlon0, par1, par2=None, E0=0, N0=0, k0=1, opt3=0, name='', auth='')
(Constructor)

 

New Lambert conformal conic projection.

Parameters:
  • latlon0 - Origin including an ellipsoidal datum (LatLon).
  • par1 - First standard parallel (degrees90).
  • par2 - Second standard parallel (degrees90).
  • E0 - False easting in meter (scalar).
  • N0 - False northing in meter (scalar).
  • k0 - Scale factor (scalar).
  • opt3 - Optional meridian (degrees180).
  • name - Name of the conic (string).
  • auth - Authentication authority (string).
Returns:
A Lambert projection (Conic).
Raises:
  • TypeError - If latlon is not ellipsoidal.
Overrides: object.__init__

Example: 

>>> from pygeodesy import Conic, Datums, ellipsoidalNvector
>>> ll0 = ellipsoidalNvector.LatLon(23, -96, datum=Datums.NAD27)
>>> Snyder = Conic(ll0, 33, 45, E0=0, N0=0, name='Snyder')

copy(self, name='')

 

Copies this conic.

Returns:
Conic, unregistered (Conic).

toDatum(self, datum)

 

Converts this conic to the given datum.

Parameters:
  • datum - Ellipsoidal datum to use (Datum).
Returns:
Converted conic, unregistered (Conic).
Raises:
  • TypeError - If datum is not ellipsoidal.

convertDatum(self, datum)

 

Converts this conic to the given datum.

Parameters:
  • datum - Ellipsoidal datum to use (Datum).
Returns:
Converted conic, unregistered (Conic).
Raises:
  • TypeError - If datum is not ellipsoidal.

toStr(self, prec=8)

 

Returns this conic as a string.

Parameters:
  • prec - Number of decimals, unstripped (int).
Returns:
Conic attributes (string).
Overrides: bases.Base.toStr
