If there is a better way to share this content, let me know. I just want people to have the map :) If you are unsure of it's contents, scan the link with Virus Total, a trusted virus checking site to see if the link is malicious. If you download the map which is not a Zip, just a JPEG, You can scan it as well with that or any other virus scanning tool. If you choose to do this, let people know its safe! I don't have any credibility here I know.
Peace!
