Comment(by nclay):

 I have already coded up a mask function that takes in a geometry and a x,
 y resolution and produces a mask.  That is all well and good if you know
 what resolution that you want you mask to be. It would be nice to be able
 to pass in a geometry and a SRID and have it pass out an appropriately
 sized mask.  This would enable, one to pass in a Geometry describing
 distances eg a circle 16 meters wide and have it project on to an
 appropriate resolution mask for that SRID.

 Can you think of anyway of doing this currently?
