color=#0000ff size=2>Not that newbie of a question. Actually its probably
not obvious but distance_sphere and distance_spheroid don't even look at the
srid of the geometry fed to them. If you give it a non-long lat
coordinates you will also get garbage results as I recall.</FONT></SPAN></DIV>

<DIV dir=ltr>Hi,<BR><BR>(This probably will score me some noob-points, but
whatever. Actually i might loose a few if i get to understand this.)<BR><BR>Why
do distance_spheroid et al. require that you specify the spheroid?<BR>Doesn't
the srid provide enough information?<BR><BR>cheers,<BR><BR>WBL<BR
