Method Details

init (self, a_ellipsoid=Ellipsoid(name='WGS84', a=6378137, b=6356752.31424518, f_=298.`...`, f=None, path='', name='')
(Constructor)

New Solve instance.

Arguments:

a_ellipsoid - An ellipsoid (Ellipsoid) or datum (Datum) or the equatorial radius of the ellipsoid (scalar, conventionally in meter), see f.
f - The flattening of the ellipsoid (scalar) if a_ellipsoid is specified as scalar.
path - Optionally, the (fully qualified) path to the GeodSolve or RhumbSolve executable (filename).
name - Optional name (str).

Raises:

TypeError - Invalid a_ellipsoid or f.

Overrides: object.__init__
