At first, I was really confused because normally land masses are a brighter color than oceans. The colors should probably be inverted so that land has a color with detail and the ocean is all black to make it easier to parse which is which.
Keys are generated in pairs. The public key is a key you can safely share. Other users encrypt data with your public key, this data can only be decrypted with your private key. Private keys should be stored locally and securely.
They aren't. Not to be rude, but aosmith is almost certainly wrong about what "Public/Private" means in this context.
I have never seen a situation where the public and private key vary in length like that. It would also make no sense for the Private Key to be half the size as that key controls decryption and is the more important one to secure (and therefore be higher bit).
Public are the certs that can't be used for signing stuff, private are basically self-signed certificates (with some percent of error due to the way of detection).
