Is it possible to use a fake projection in PostGIS?

I'm creating a spatial table in PostGIS. My geometries are going to be abstract, not related to a real world. So I need some fake SRID. What is the right way to do it?

Solution

  • If your coordinates are not part of any spatial reference system, use SRID=0.

    (Or if you have older PostGIS versions, this is SRID=-1)
