Demo maps for Geo Mapgen (https://github.com/Gael-de-Sailly/geo-mapgen)

Geo Mapgen Demos

This repository contains land databases for my Minetest mod Geo Mapgen. This mod comes with a Python tool that converts raw elevation / land cover data into a database, that is read on map generation. However I can understand that this may be tedious for just generating one world, and it's perhaps more convenient to directly have access to the database. So I'll make here a collection of my favorite maps. If you want to add a map, please ask me on the forum topic or by forum PM.

Using the maps

  • Download and install Geo Mapgen
  • Create a blank Minetest world and enable geo_mapgen mod. Don't start the game.
  • Copy your desired data file from this repository to your Minetest world folder, and rename it heightmap.dat.
  • Start the game and enjoy!
