minecraft city maps fully furnished 1.12.2 on regular world

To make the image, I primarily used a C library called Cubiomes that simulates aspects of Minecraft's terrain generation code and is designed to be used to find special seeds.

At 6.13 GB, it's too large for me to easily upload in one session (I tried leaving it overnight, but at some point the upload ended while I was asleep, maybe my PC restarted on its own, IDK), so I've split the binary into two files, and included a Windows Batch file that will assemble the image from them (if you're not on Windows, the keyword you'll want to search is 'file concatenation', and the CRC32 checksum of the image is 454299DD). Here is a link to download the image file. Feel free to comment if you find that other image programs can open it. There may be more programs that can open it, but I stopped looking after finding one that worked.

And zooming and scrolling is actually surprisingly smooth. It takes about 10-20 minutes, but it does open it.

The Windows image viewing program can't open it, Chrome can't open it, Paint.NET can't open it, but GIMP can open it. Opening a 60k by 60k image 6.13 GB in size is of course, not easy. The map is colored based on the biome of that point, and for this, AMIDST's color palette is used (though admittedly, at this resolution, the palette could definitely use more contrast between land and water).

At this resolution, biomes are mostly shown with a few pixels (some small ones are only one though), and so this resolution is enough to show some shape of biomes and bodies of water (which are just biomes). Here's a zoomed in view of a small section around the origin. The image has a resolution of 60001 by 60001, a space of 1 km (1000 blocks) between each pixel, and is 6.13 GB (6,592,627,966 bytes) in size.
