[postgis-users] very inaccurate distance using "distance_spheroid" on geometric coordinates

[Paul Ramsey]

ST_Distance_Sphere and ST_Distance_Spheroid return in meters, not  
kilometers, so they think the distance is about 495km.  What makes  
you so sure that's wrong? I checked in a transformed projection and  
got a similar result also.
