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 with (ellipsoidal) datum (`LatLon`). `par1` - First standard parallel (`degrees90`). `par2` - Optional, second standard parallel (`degrees90`). `E0` - Optional, false easting (`meter`). `N0` - Optional, false northing (`meter`). `k0` - Optional scale factor (`scalar`). `opt3` - Optional meridian (`degrees180`). `name` - Optional name of the conic (`str`). `auth` - Optional authentication authority (`str`). Returns: A Lambert projection (Conic). Raises: `TypeError` - Non-ellipsoidal latlon0. 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) |
Copy this conic. Returns: The copy, unregistered (Conic or subclass thereof). Overrides: bases._Named.copy

### toDatum(self, datum) |
Convert this conic to the given datum. Parameters: `datum` - Ellipsoidal datum to use (Datum). Returns: Converted conic, unregistered (Conic). Raises: `TypeError` - Non-ellipsoidal datum.

### convertDatum(self, datum) |
Convert this conic to the given datum. Parameters: `datum` - Ellipsoidal datum to use (Datum). Returns: Converted conic, unregistered (Conic). Raises: `TypeError` - Non-ellipsoidal datum.

### toStr(self, prec=8) |
Return this conic as a string. Parameters: `prec` - Optional number of decimals, unstripped (`int`). Returns: Conic attributes (`str`). Overrides: bases._Based.toStr
