Yet (not) Another Maps Pack (YnAMP) provides Earth maps in different sizes with true starting locations, as well as a few more features. Read more about them in the civfanatics forum post.

If you run Civ6 on a PC, see the forum post above for installation instructions.

Mac Steam Users use the following command:

cd ~/Library/Application Support/Sid Meier's Civilization VI/Mods/

Mac non-Steam users use the following command:

cd /Applications/Civ6.app/Contents/Assets/Base/Assets

Once inside this directory, clone this repo with the following git command:

git clone https://github.com/Gedemon/Civ6-YnAMP.git

If you do not have git, it can be installed here.

Enjoy!
