Nortantis v1.0

An open source fantasy map generator for Windows and Linux.

It uses a simple tectonic plate simulation to create islands and continents with trees, rivers, and mountains. The result has the appearance of an old-fashioned hand-drawn map.


To run Nortantis you must have Java 10 or later installed. If you don't already have it installed, you can find it here. Make sure to choose 64-bit if you have a 64-bit computer (almost all computers are). With 32-bit Java you can't generate high resolution maps because it can't allocate enough memory.

Your computer must have at least 3 GB of RAM memory


The download above gives you a zip file containing an executable jar file and a folder of assets such as mountain and tree icons. The way to run Nortantis depends on your operating system:

-Windows - unzip the downloaded file, open it, and double click run.bat.
-Linux - unzip the downloaded file, open it, and run run.bash

Generating a map requires some intense computing, so it can take up to a minute depending on the speed of your computer and the size of the map you generate.

If you want to generate maps at higher resolutions than the default, you can modify run.bat (or run.bash for Linux) to increase the amount of memory Nortantis can use. Find the line that contains -XX:MaxRAMPercentage=50.0. The 50.0 is the percentage of RAM memory it can use. Change it to whatever limit you want up to 100.0. Make sure to include the .0 at the end because Java requires it. When done, that line should look like: When Nortantis opens it checks the amount of RAM allocated and adjusts the maximum on the Resolution slider in the Background tab to the maximum size of map you can generate with that amount of RAM.
