SO0285 National Grid Square

Based in the Mid and West Wales region of Scotland.

SO0285 is within the post town of Llandinam, Montgomeryshire.

The square is within Powys - Powys council.

The Point of Origin (0,0) is 415.25 Kilometres away. This is where the National Grid starts around 80 kilometres west of the Isles of Scilly.

This extract is taken from the Ordnance Survey six-inch to the mile series surveyed from 1888-1913. The scale is 1:10,560.

The Square overlayed over the map represents the extent of SO0285 and the vertical and horizontal line divides the square into four quadrants

Dividing the SO0285 Square to get a six figure Grid Reference

A helpful reminder for calculating grid references is across the landing and up the stairs.

For example if your house was located in a square that in the fourth square across and sixth square up and you wanted to work out its six figure grid refence.

First, You would divide the four figure grid reference into three parts. SO , 02 and 85

Count across starting with zero. This would give you three. Make a note that X for Across (A Cross) = 3.

Count up starting with zero. This would give you five. Make a note that Y = 5.

So to put it together SO + 02 + 3 + 85 + 5 would give you the six figure grid reference of SO023855

SO	02		85
SO	02	3	85	5

A six figure grid reference would be accurate to 10 metres. To achieve a greater level of accuracy this 10 metre square would be divided into a grid 10 by 10 and the process repeated.

This would produce an 8 figure grid reference that would be accurate to a square metre!
