One solution would be to extend this new standard with a "box" variant that
would create a box instead of the circle that is created with the "u"
uncertainty parameter.

Something like: *geo:37.000000,-93.000000;box=10000*

I have had queries like this working at the state and county level for
sometime in the GeoSpecies Knowledge Base

See http://about.geospecies.org/sparql.xhtml

However, I think it would would be better if we had something that was at a
smaller spatial scale, uniform and global.

The EUNIS also has an "expectedIn" so it would be good if we can work out
some standard way of saying

<Organism> <expectedIn> <geographicalArea>
