If you move the mouse pointer over the map, a box should appear top right. The letters and numbers in the box will show you the grid reference of the square the pointer is in. This is a 'four-figure' grid reference
The squares are outlined in blue, and are 1 km by 1km - known as a 'monad'.
The section of the map chosen to start with allows you to see some reference numbers on the map, which should match the numbers top right. The first two characters in the grid reference - the letters - denote a square 100 km by 100 km. They will change from SO to SP as you move the mouse pointer from left to right across the 00 line. These are the only two letters pairs that we need in Worcestershire.
The first two numbers - the 'eastings' - are for the numbers going across -
to the east!
The second two numbers - the 'northings' - are for the numbers going up You should be able to see more of these if you drag the map about by holding down the left mouse button, or using the arrows on the left had side of the map.
While 1 km accuracy is enough for many things, it would leave it almost impossible to re-find, and often a 'six-figure' grid reference is preferable. Use the links below to change pages.
