Maybe I'm dense but this seems simply wrong. You want to define the
values of the coordinates when they have no values? This sounds like I
give you a graph with the axes unlabeled and then you are going to
decide what the axes are. If we have no unit information we can only
plot this as x and y.
We could start guessing based on the size of the values but I don't
think that's what you are talking about.
Regardless, only the user can really start assigning 'default' CRS's;
uDig can only help to the extent of informing the user some key stuff is
missing and providing easy ways to fix missing info.
