Remlia Map Breakdown

I'm gearing up to run Princes of the Apocalypse, but in my home setting of Generica (of which Remlia is the main country where humans live).

I've run G+ games there before, but in different sections of the country. Here's a quick image to show where exactly Eastern and Western Remlia are located on the map proper.

Also I have no idea how the scale works. At times I've described Remlia being about as big as Washington state, other times its more on par with Ontario.
