What is OS Map Interpretation & Fieldwork Mapping?

Interpreting an Ordnance Survey (OS) map involves more than just finding locations; it's about understanding the landscape and the relationships between different features. This means identifying physical features like rivers and mountains, and human features like settlements, roads, and industry. For fieldwork, maps are crucial for planning routes, selecting sites for data collection (e.g., for a river study), and for presenting results, for example by using proportional symbols or desire lines.

Board notes: Map interpretation is a higher-level skill tested by all boards (AQA, Edexcel, OCR). Questions often ask students to describe the character of an area or explain the location of a feature using only map evidence. Fieldwork mapping skills are also explicitly tested, particularly in questions about geographical enquiry.

Worked example

Common mistakes

• 1Simply listing map symbols without interpreting them. Instead of saying 'there is a church, a pub, and a post office', you should infer that 'this is a village that likely provides services for the surrounding rural area'.
• 2Ignoring the contour lines when describing a route. When planning a walk or describing a road, you must refer to the relief, for example, 'the road follows the valley floor, avoiding the steep slopes on either side'.
• 3Producing a fieldwork map without the correct conventions. All maps should have a title, a north arrow, a key, and a scale to be geographically correct.

Frequently asked questions

• How can you tell what a building is used for on an OS map?

  The map key shows symbols for important buildings like places of worship, schools, post offices, and tourist information centres. The shape and layout of buildings can also give clues; for example, large rectangular buildings on the edge of a town might be a factory or a supermarket.

• What is a transect?

  A transect is a line along which you take measurements or make observations. For example, in urban fieldwork, you might use a transect line running from the city centre to the suburbs to record how land use, building height, or environmental quality changes with distance from the centre.
