[postgis-users] ST_Azimuth on the spheroid

[Francis Markham]

Is there, or are we likely to see a way of calculating ST_Azimuth on the
spheroid?

Is an implementation, overloading ST_Azimuth to accept the GEOGRAPHY type to
be expected?

I suspect the code has already been written, given the existence of
ST_Distance_Spheroid which presumably uses Vincenty's Inverse formula (which
also calculates azimuth).

Cheers,

Francis Markham
