[postgis-devel] Box2D modify srid

[Etienne Bellemare]

But if you try an operation with a box2d, it will raise the fact that the
srid's are different. Even if the box doesn't have an srid and that it
shouldn't care.
So, for my own edification, once you setsrid it transforms from a box to a
geom as well as when you make an operation (e.g. st_dwithin) ?
