Real World Map Minecraft

Being one of the largest custom maps in Minecraft means The Recreation of the Earth map is about as complete a scale of the real world as players are likely to. The download file is 4GB zipped and once unzipped it is 12GB This is an exciting Minecraft map that is an exact heightmap copy of Earth scaled at 1 1000 That.

Real world map in minecraft Jan 24, 2015, I had the idea to build a map of the real world in Minecraft. Now, I did it and here’s how it works.

To build a map based on real geographic data, basically two things are needed: • Geographic data of the world, mainly elevation information. Emantha neram chesanu ringtone. • The ability to create a map in Minecraft format. After some googling, I found which provides an elevation model of the whole earth with a resolution of 1 arc second (30 meters).

It’s freely available but quite big (500 GB). There are a lot of tools around Minecraft, but surprisingly, I found nothing that fitted my needs. Fortunately, the provides a detailed description of Minecraft’s file format.

It’s a tree of named values, something like a binary json. So I wrote my own file loader / saver. With these two ingredients, I could create my first maps.

I ended up with one single big file containing all elevation data and an index file that maps world coordinates to positions in the data file. The index fits into RAM, so one disk access per point is needed.

It’s ok, but surely, there are better solutions. To improve the map, I wanted to include lakes and rivers. I found, a data set which contains the shapes of the oceans, lakes and rivers of the world. Additionally, there’s which provides a map of sea depths. Together this allows to create pretty nice maps. I spent a lot of time flying through the world Hawaii Grand Canyon Swiss alps Norwegian fjords The difficulty here is to merge the three data sources into one consistent model. I found a solution that is not perfect (due to rounding errors or projection issues?) but works.

That’s the current state of this project. The source code can be found on but it’s pretty ugly. For the moment, I do not plan to continue, but I have several ideas how it could be improved: • Use data from to add borders, cities, streets or railroads.

• Use this to determine the type of floor (grass, forest, dirt, sand, ice etc). • Correct the inconsistencies between elevation and water models and add different projections.
