Method Details

init (self, slat1, clat1, slat2, clat2, k1=1, datum=Datum(name='WGS84', ellipsoid=Ellipsoids.WGS84, transform=Tran`...`, name='')
(Constructor)

New AlbersEqualArea4 projection.

Arguments:

slat1 - Sine of first standard parallel (scalar).
clat1 - Cosine of first standard parallel (non-negative scalar).
slat2 - Sine of second standard parallel (scalar).
clat2 - Cosine of second standard parallel (non-negative scalar).
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 - Negative clat1 or clat2, slat1 and slat2 have opposite signs (hemispheres), invalid k1 or no convergence.

Overrides: object.__init__
