astromodels.utils.vincenty module

astromodels.utils.vincenty.vincenty(lon0, lat0, a1, s)

Returns the coordinates of a new point that is a given angular distance s away from a starting point (lon0, lat0) at bearing (angle from north) a1), to within a given precision

Note that this calculation is a simplified version of the full vincenty problem, which solves for the coordinates on the surface on an arbitrary ellipsoid. Here we only care about the surface of a sphere.

Note: All parameters are assumed to be given in DEGREES :param lon0: float, longitude of starting point :param lat0: float, latitude of starting point :param a1: float, bearing to second point, i.e. angle between due north and line connecting 2 points :param s: float, angular distance between the two points :return: coordinates of second point in degrees
