Mastering Map Skills: Ordnance Survey Maps

Mastering Map Skills: Ordnance Survey Maps

Learning Objectives

At the end of the lesson, you will understand map symbols, Eastings and Northings, and know how to create 4 and 6 figure grid references.

What do you already know about reading maps and their symbols?

Understanding Map Symbols

Map symbols are pictorial representations of features on a map. They help identify physical and human-made features.

Eastings and Northings

Eastings run vertically, Northings run horizontally. They help locate points on a map grid.

4-Figure Grid References

A 4-figure grid reference identifies a square on the map. It's given as (Eastings, Northings).

Creating 4-Figure Grid References

To create a 4-figure reference, find the bottom-left corner of the grid square using eastings and northings.

6-Figure Grid References

A 6-figure grid reference gives more precise location. It uses (Eastings, Northings) with additional digits.

Creating 6-Figure Grid References

For a 6-figure reference, estimate the position within the grid square to add a third digit to both Eastings and Northings.

Interactive Map Activity

Practice identifying symbols and creating grid references on a sample Ordnance Survey map.
