Converting Jezero Crator (Mars) Into Minecraft | HiRISE and World Painter

Welp. Minecraft needs a NASA Supercomputer to finish this project. How am I doing this? I'm taking grayscale images from HiRSE of Jezero Crator on Mars and using World Painter, I will eventually have a interactive, Minecraft world to view it in. For now, I cannot wait 4 hours to complete so I will have to size down.
