I've just discovered a mapping website that has something perfect for model making...
The site is called
http://www.what3words.comand its prime purpose is to make locating specific points anywhere throughout the world very easy to specify when identifying and/or telling others where the location is. Instead of using latitude and longitude values....which they consider to be too complicated

...they've split the whole of the world's surface up into 3m squares....and named each square with three names.....such as "elephant.sandwich.pint". Good idea? Well yes...and no! Either way, a side effect of this is that you can view anywhere in the world as a satellite view that is overlaid with a 3m square grid.
Here's an example:

This is going to make working out sizes of any building an easy and simple job!!!
