Hi Lynda
Your post is really sweet, and shows how thoughtful people in the mapping blogosphere can be -- thanks! -- and is also an encouragement to me to make the next set far better; as we discussed by email, good data in this area for various reasons are sparse, often unreliable, and full of caveats. I'm working on this and will let you know when I get a moment of free time to update, and improve, them. atb
