Symbols, Sketches and Plans - Lesson Summary

The letters, pictures, lines, and colours used on the map are called symbols. Symbols are used to represent different features on a map.

Symbols give more information in a limited space, make maps both easy to draw and easy to read, and help you find your way in an unknown area.

Maps use a universal language that everyone can follow. The universal symbols used in maps are referred to as conventional symbols.

According to an international agreement, symbols follow a common colour code.
  • Blue is used for representing water bodies,
  • Brown for mountains,
  • Yellow for plateaus, and
  • Green for plains
 
Using symbols gives you a number of advantages:
  • Give a lot of information in a limited space
  • Symbols makes it easy to draw and read maps

A sketch map is drawn without a scale, based on memory and observation, and rRepresents the main features of an area.

A plan is drawn to scale, represents a small area on a large scale and provides the finer details, such as the length and breadth of a certain area.
