[postgis-users] Length, distance, area using SRID 6326

[Fermín Pieri]

Hi, I am using SRID 6326 as the spatial reference id of the geom column. But
when i try to use length, distance and area functions, the results are not
what i expect (of course, using spherical calcultations) Any idea? Opengis
specification says that this functions return the result using the SRID of
the geom column. Why postgis include distance_sphere, length_spheroid, etc.?
I tried length_spheroid and the result is what i need but it takes a long
processing time. I will appreciate somebody's help

Thanks
