Hi,
 
            I have a point table with 150 000 records (bathymetric
survey).  The points can be really close from each other (sometimes < 1
mm) and I do not need as much precision.  I would like to filter the
table to have no point closer than 1 m from any other point. 
 
Any clue on how to do this?
 
Thank you
 
Simon
