Minecraft NI map

A free, downloadable Minecraft map is available for Northern Ireland using Ordnance Survey of Northern Ireland (OSNI) digital map products. Land & Property Services (LPS) developed the map.

Minecraft fans can explore, build and create their own world across Northern Ireland.

The Minecraft NI map has over five billion blocks and equates to almost 14,000km² covering all of Northern Ireland.

Requirements

The Minecraft NI map pack is 1 GB in size. To download the map you will need:

  • a licensed copy of Minecraft for PC or Mac
  • 3 GB of free disk space
  • minimum of 2 GB of memory

Installation

Follow the installation instructions in the OSNI Minecraft NI readme file

Getting around in the Minecraft NI map

The initial start point when you enter Minecraft NI is Belfast City Hall. Begin by exploring Belfast city centre and decide where you want to go next.

You can:

  • navigate the map within the Minecraft Software
  • teleport to a specific location using the Minecraft co-ordinates generator

How to use the Minecraft Coordinates generator

You can teleport around the Minecraft map using the teleport command: /tp X Y Z. Use the Minecraft Coordinate generator link below to find the X and Z coordinates of where you want to go. Back in Minecraft use the teleport command to enter your location (the Y value is the elevation, a Y value of over 50 is usually a good starting point).

For example, coordinates to teleport to Belfast would be /tp 12274 50 10779, Slieve Donard in the Mournes would be /tp 12435 150 14576.  If you teleport somewhere and end up underground, try again with a higher Y value.

LPS created a story map on Spatial NI that shows how various local landscapes look in Minecraft.

How LPS made the map

Land & Property Services (LPS) used a custom built computer programme to create the Minecraft NI map in the Anvil file format.

For each 100 x 100km grid square:

  • load height data from the OSNI terrain files and interpolated to 25m
  • load image data from OSNI vector files
  • both datasets were processed in Arc GIS 10 and exported into images
  • using a custom generator, these two OSNI images representing terrain type and height are used to generate the world file

Each block represents a ground area of 12.5m². The raw height data is stored in metres and must be scaled to a suitable resolution. The maximum represented height of the landscape is 1500 m. Dimensionally, each map block is a cuboid measuring 12.5m x 12.5m x 5m.

How the data is represented

In Minecraft real life features are constructed using different material types available in Minecraft.  LPS  built the map using:

Legend of Minecraft images

Green clay represents areas in the Republic of Ireland. Minecraft NI is not compatible with the Ordnance Survey of Great Britain version.
