How to Take a 4-Figure Grid Reference with Steve Backshall & Ordnance Survey

#GetOutside champion and naturalist Steve Backshall continues his series of map reading videos with Ordnance Survey by explaining how to work out a four-figure grid reference.

These look like this: SU 24 10

With a 4-figure grid reference you can find an area on a map, or take note of a location. Steve shows how you can calculate a 4-figure grid reference from an OS Map, and define a part of a map of one square km.

If you want more accuracy, there are also 6-figure grid references ? see the follow up video at https://www.youtube.com/watch?v=FXuo_...
