... and from a comparison with GIS data, probably irrelevant. From our playing
with the GIS community there is such a scale disconnect (at the moment), that
sphericity and ellipsoidal issues with grid boxes scales of tens if not
hundreds of km just don't matter ...

Having said that, one day they will (maybe as mesoscale models are at the km
resolution now, they already are), so it's a great idea to be asking the
question now. So it's not so much does the information get recorded, but if
we did, where would we put it?
