[postgis-users] ST_Distance_Spheroid SRID

[Francis Markham]

Hi all,

The documentation for ST_Distance_Spheroid (
http://postgis.refractions.net/docs/ST_Distance_Spheroid.html ) states
that it "does not look at the SRID of a geometry and will always
assume its in WGS 80 long lat."

What is WGS 80?  Is it WGS-84, GRS-80, or something else entirely?

Cheers,

Francis
