I find that an excellent proposal, right down to the's final paragraph 
(below), which would be particularly helpful as an additional tool for 
dialectologists used to handling isoglosses (something like isobars, for 
the uninitiated), which such geocoordinates could be used to define and 
further refine.

Maith thú, a Chaoimhín.
