Understanding map symbols

Ordnance Survey maps use map symbols, known as a 'key' or 'legend', to show where things are on the ground. Using our map symbol guides below you can find out what everything means on the OS Explorer and OS Landranger maps, and on OS getamap.

The map symbols for 1:25 000 OS Explorer maps and 1:50 000 OS Landranger maps differ because of the scale of the mapping - OS Explorer maps show more detail because they cover a smaller area. 

Scroll down to watch the Simon King video on map symbols, or read on.

The type of symbols on Ordnance Survey maps can be broadly categorised as:

  • Contours - lines showing the height (elevation) and shape of the terrain;
  • Roads - types of roads from motorways to unfenced farm roads;
  • Leisure signs - showing atrractions, viewpoints, places to go, camping and caravan sites, national parklands and trails;
  • Terrain and landscape features - scree, mud, sand, rocky outcrops, cliffs; and
  • Paths - footpaths, bridleways and routes, some are rights of way, some aren't.
