Sweet mother of God, it’s the autist motherlode! The industrial folks over at MinecraftForum.net have collaborated to create the ultimate experience in exploratory MineCraft. After downloading the map, players can explore a fully playable 1:1 Planet Earth that includes cities, rivers, and caves, along with the appropriate biomes and ore-dumps.
The creators described it as follows:
“The world is fully playable (includes ores, trees, etc). Elevation has been scaled to fit the constraints of a Minecraft world. Sea level was adjusted to 40 blocks which puts Mt. Everest at 121 blocks high. The Earth was generated with various images from NASA (including landmass, satellite, elevation, and vegetation maps) using a custom python script incorporating codewarrior’s pymclevel python library.”
You can download the map here, but be warned: The file is a 450MB file, that uncompresses to 3.5GB. At the time of the writing, the server hosting the files were overloaded and we were told it would take up to 10 hours do download.
I've started my download already.
