# 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: 22.04.07

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` - Optional class to return the Lambert location (Lcc). `name` - Optional `Lcc` name (`str`). `Lcc_kwds` - Optional, additional `Lcc` keyword arguments, ignored if `Lcc` is `None`. Returns: The Lambert location (Lcc) or an EasNor3Tuple`(easting, northing, height)` if `Lcc is None`. Raises: `TypeError` - If `latlon` is not ellipsoidal.
