[postgis-users] ST_Azimuth on the spheroid

[Paul Ramsey]

Indeed, the code is there, it just needs to be exposed to SQL. Do you
build your own PostGIS Francis? If so you can open a ticket for the
feature and I'll provide a patch there you can apply. If not, it could
be a long wait for PostGIS 2.0 and new features. (several months)
