[postgis-users] Moving point grid

[Guido Lemoine]

transform your points to a UTM projection (e.g. SRID=32632 for UTM Zone 
32 N,
hopefully, they're all in one zone), then translate -13000, -13000 and 
transform back
to SRID=4326.

select astext(transform(translate(transform(SetSRID(Makepoint(9.0, 
45.0), 4326), 32632), -13000, -13000), 4326));

yields POINT(8.83539247380864 44.88285511722)
