This article is designed as a guide to using grid
references. It teaches the basic principles of grid referencing, and allows
you to try out your skills as you learn them.
This article has recently been redesigned with animated diagrams. These
should load quickly as they are small gif format, but on really slow
connections they may take a few seconds. The cycles last between about 5 and
20 seconds - please be patient and watch them from the beginning - they
constantly repeat themselves if you miss them the first time.
Further work is required to complete this article. So far
you can learn about four and six figure references, and practise using them.
Over the next few days the article will be expanded with more practise
sections and explanation of the national grid.
In
the UK, all ordnance survey maps follow the National Grid. This divides the
country into 91 squares (13x7) each of which is 100km by 100km. These can be
further divided down. We will look at the "real" grid in more detail later, but
first let us look at how to take standard 4 figure grid references.
The first point to remember when taking a grid reference, is
to always take the eastings, then the northings. Put more simply "Along the
corridor and up the stairs".
