The map reference conversion spreadsheet (xlsm) will help convert between full national grid references and map tile references that use the 100km square letters. The map on the right shows Ordnance Survey (OS) maps of different scales according to the zoom amount. However, it is also useful to be able to read a grid reference from a map. The Ordnance Survey (OS) devised the national grid reference system, and it is heavily used in its survey data, and in maps based on those surveys. The OS maps for Great Britain are divided into a grid of 100km x 100km squares, each with an individual two letter reference prefix. Many biological recorders use hand-held GPS devices or apps on smart phones to record the grid references for their observerations. The first two numbers are the distance east from the western edge of the 100km square and the next two give the distance north from the southern edge of the 100km square.

The numbers of a grid reference identify a location within a 100km square. For the Outer Hebrides these are NA, NB, NF, NG, NL and HW and can be found in the corners of OS maps. The OS maps for Great Britain are divided into a grid of 100km x 100km squares, each with an individual two letter reference prefix. To enable us to check where an observation was made it is important for us to have a grid reference taken from an Ordnance Survey (OS) map or a GPS device. On the sparsely populated islands of the Outer Hebrides there are very few place names and on the OS maps these are in Gaelic.
