Hi,

as far as I can tell, there's no built-in functionality to get a full plus 
code list for an arbitrary area. However, I implemented something like this 
a while ago, using a scanline algorithm typically used in computer 
graphics. I haven't looked at that code for years, there might still be 
one-off errors around the edges, but it generally works.

I just generated this list of full plus codes from the coordinate list in 
your KML file, I hope it helps.

Here's the code, in case you want to have a look at 
it:
