Note: The British Grid system is an alternative
to the more commonly used Ordnance
Survey Great Britain, OSGB. A relationship
between British Grid and OSGB may be
seen by comparing the following two sets
of coordinates which represent the same
location;
British Grid X:528481 E Y:179816 N
OSGB TQ 28481 79816
The Active 10 gives OSGB grid references to
10 gures. The most commonly used system
in the UK is the 6-gure grid reference. In the
example above, the 6-gure grid ref would be
(TQ) 284 798.
