The Minecraft Overviewer is a command-line tool for rendering high-resolution maps of Minecraft worlds. It generates a set of static html and image files and uses the Google Maps API to display a nice interactive map.
The Overviewer has been in active development for over a year and has many features, including day and night lighting, cave rendering, mineral overlays, and many plugins for even more features! It is written mostly in Python with critical sections in C as an extension module.
Full disclosure disclaimers of what The Overviewer is not.
It does not run fast. Because of the high level of detail, initial renders of a world can take some time. Expect minutes for medium worlds, hours for large to huge worlds. Subsequent renders are much faster due to the caching.
Also note that speed is improving all the time. We continually make efficiency improvements to The Overviewer. Besides, for the level of detail provided, our users consider it worth the time!
The Overviewer is not targeted at end users. We mainly see Overviewer fitting in best with server operators, rendering their server’s map for all users to view.
You are welcome to use The Overviewer for your single player worlds, and it will work just fine. However, since the only interface is currently command line based, you will need to know a bit about the command line in order to operate The Overviewer.
This is a quick list of what’s required to run The Overviewer. It runs on Windows, Mac, and Linux as long as you have these software packages installed:
The first three are included in the Windows download. Also, there are additional requirements for compiling it (like a compiler). More details are available in either the Building or Installing pages.
The Overviewer works with Linux, Mac, and Windows! We provide Windows and Debian built executables for your convenience. Find them as well as the full sources on our Github Homepage.
If you are running Windows, Debian, or Ubuntu and would like the pre-built packages and don’t want to have to compile anything yourself, head to the Installing page.
Running Windows and not familiar with the command line? Head to the Windows Newbie Guide page.
If you would like to build the Overviewer from source yourself (it’s not that bad), head to the Building page.
