THE ORDNANCE SURVEY
MINECRAFT MAP OF GREAT BRITAIN 2.0

Created September 2014


The purpose of this map was to focus on gameplay and realism and we feel this has been achieved
with an increase of scale. The generation of ore and trees enables near normal gameplay to occur.
Lighting which was a major bug in the previous version has been fixed enabling mob spawning and day/night
to occur as normal.

INSTALLATION


Within OSGB.zip is a folder named OSGB which will need to be copied to your computers minecraft installation directory within the saves folder.

Mac (OS X)

In the Finder, from the Go menu, select 'Go to Folder', then type: ~/Library/Application Support/minecraft, and click Go.

Linux

~ is within your home directory, usually /home/YOURNAME, so ~/.minecraft would be /home/YOURNAME/.minecraft/.


Once located place the OSGB file within "/minecraft/saves" sub directory



CO-ORDINATES


The co-ordinate system within minecraft measures along the x and z and 
these are based on a scaled version of OSGB 1936 co-ordinate system.

The teleport command can be used to jump around the map.

/tp [x] [y] [z]

If you know the location of a place in Northings and Eastings, 
the exact position in minecraft can be calculated using the following.

Minecraft X = [Easting Co-ordinate] / 25
Minecraft Z = (1,300,000  -  [Northing coordinate]) / 25
