[postgis-users] Looking for function to analyze linestring and points

[Baris YILMAZ]

Hi ,
   
  I have some points arbitrarily on a map, which are read from postgis database. And  I have a linestring which goes through the area of these points from west to east. Is there a function to find out, whether a  point falls on the to south of the linestring or the other part? 
   
   
  Any help will be appreciated.
   
  Thank you.
  Baris
