The Secret Cartographer

What you'll make

A treasure map or desk-based route, a set of precise clues, a distance calculation and a route-choice explanation.

What you'll learn

• Scale and measuring distance
• Compass direction and map symbols
• Contour lines and height
• Four- and six-figure grid references — and how they differ from latitude and longitude

You'll need

Printed OS extract or library OS Explorer map (optional) · Ruler, string, paper

The practice map is INVENTED. For real map work, use a genuine OS extract under its licence. Every activity here uses buttons and typing, not dragging.
