Method Details

init (self, lat1, lat2, k1=1, datum=Datum(name='WGS84', ellipsoid=Ellipsoids.WGS84, transform=Tran`...`, name='')
(Constructor)

New AlbersEqualArea2 projection.

Arguments:

lat1 - First standard parallel (degrees).
lat2 - Second standard parallel (degrees).
k1 - Azimuthal scale on the standard parallels (scalar).
datum - Optional datum or ellipsoid (Datum, Ellipsoid, Ellipsoid2 or a_f2Tuple).
name - Optional name for the projection (str).

Raises:

AlbersError - Invalid lat1m lat2, k1 or no convergence.

Overrides: object.__init__
