Method Details

init (self, lat0, lon0, datum=Datum(name='WGS84', ellipsoid=Ellipsoids.WGS84, transform=Tran`...`, name='')
(Constructor)

New azimuthal GnomonicKarney 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:

ImportError - Package geographiclib not installed or not found.
AzimuthalError - Invalid lat0 or lon0.

Overrides: object.__init__

Property Details

geodesic

Get this projection's wrapped Karney Geodesic, provided package geographiclib is installed.

Get method:: _fget(inst)
Set method:: _fset_error(inst, val) - Throws an AttributeError, always.
Delete Method:: _fdel(inst)
