What are the main symbols used in Ordnance Survey maps?

Ordnance Survey maps use symbols like contour lines, buildings, roads, water features, vegetation, and tourist information to represent features.

Ordnance Survey (OS) maps are a crucial tool for understanding the geography of an area. One of the most important symbols is the contour line, which shows elevation and the shape of the land. Contour lines are drawn at regular intervals, and the closer they are together, the steeper the terrain. This helps you visualise hills, valleys, and flat areas.

Buildings are represented by small black squares or rectangles, and different types of buildings, such as churches or schools, have specific symbols. Roads are another key feature, with different types of roads shown in varying styles and colours. For example, motorways are shown in blue, A roads in red, and minor roads in yellow or white.

Water features are also prominently displayed. Rivers and streams are shown in blue, with thicker lines for larger rivers. Lakes and reservoirs are shaded blue, and marshes or boggy areas are often marked with a blue, wavy pattern. Vegetation is indicated by different shades of green, with forests and woodlands shown as green areas with tree symbols.

Tourist information is also included on OS maps. Symbols for campsites, viewpoints, and picnic areas help users find places of interest. Public footpaths and bridleways are marked with dashed lines, making it easier for walkers and cyclists to navigate.

Understanding these symbols is essential for anyone using an OS map, whether for hiking, planning a trip, or studying geography. They provide a detailed and accurate representation of the landscape, making it easier to interpret and analyse the physical and human features of an area.
