The forward computation involves determining latitude, longitude +and back azimuth of a terminus point given the latitude and longitude of an +initial point, plus azimuth and distance. The inverse computation involves +determining the forward and back azimuths and distance given the latitudes and +longitudes of an initial and terminus point. + +Input coordinates can be given as python arrays, lists/tuples, scalars or +numpy/Numeric/numarray arrays. Optimized for objects that support the Python +buffer protocol (regular python and numpy array objects). |
