Azimuthal gnomonic projection, a Python version of Karney's C++ class Gnomonic, based on exact geodesic classes GeodesicExact and GeodesicLineExact.

Method Details

### __init__ (self, lat0, lon0, datum=Datum(name='WGS84', ellipsoid=Ellipsoids.WGS84, transform=Tran`...`, name='') (Constructor) |
New azimuthal GnomonicExact projection. Arguments: `lat0` - Latitude of center point (`degrees90`). `lon0` - Longitude of center point (`degrees180`). `datum` - Optional datum or ellipsoid (Datum, Ellipsoid, Ellipsoid2 or a_f2Tuple) or scalar earth radius (`meter`). `name` - Optional name for the projection (`str`). Raises: `AzimuthalError` - Invalid `lat0` or `lon0`. Overrides: object.__init__

Property Details

### geodesic Get this projection's exact geodesic (GeodesicExact). Get method: _fget(inst) Set method: _fset_error(inst, val) - Throws an `AttributeError`, always. Delete Method: _fdel(inst)
