Module lcc

Lambert Conformal Conic (LCC) projection.

Lambert conformal conic projection for 1- or 2-Standard Parallels classes Conic, Conics registry, LCCError and position class Lcc.

See LCC, Lambert Conformal Conic to Geographic Transformation Formulae, Lambert Conformal Conic Projection and John P. Snyder 'Map Projections - A Working Manual', 1987, pp 107-109.

Version: 24.06.24

Classes
	Conic Lambert conformal conic projection (1- or 2-SP).

Function Details

toLcc (latlon, conic=Conic(name='WRF_Lb', lat0=40, lon0=-97, par1=33, par2=45, E0=0`...`, height=None, Lcc=<class 'pygeodesy.lcc.Lcc'>, **name_Lcc_kwds)

Convert an (ellipsoidal) geodetic point to a Lambert location.

Arguments:

latlon - Ellipsoidal point (LatLon).
conic - Optional Lambert projection to use (Conic).
height - Optional height for the point, overriding the default height (meter).
Lcc - Class to return the Lambert location (Lcc).
name_Lcc_kwds - Optional name=NN (str) and optional, additional Lcc keyword arguments, ignored if Lcc is None.

Returns:

The Lambert location (Lcc) or if Lcc is None, an EasNor3Tuple

(easting, northing, 
          height)

Raises:

TypeError - If latlon is not ellipsoidal.
