Question

Write three ways of representing scale on a map

Answer 1

there are three main methods of representing scale on a map;

1-  A statement - in this method scale is stated in words or we make a statement about it e.g., 1 cm to 1 km, 1 inch to 5 miles.

2-Linear or graphic scale-  in this method the scale is represented by a straight line divided into equal parts [primary and secondary] to show what these markings represent on the actual ground.

3- the numerator is always expressed as unity i.e., one unit map distance is equivalent to a number of units of ground distance. This fraction is called representative fraction.

Answer 2

The three methods used to represent the map scale are:

Bar Scales:

• Bar scales display scale using image format.

• The actual length of the bar scale indicates what that length represents in real world units.

Speaker Scale:

• For example the word scale, 1 ″ = 100 ′ means one inch of the map represents 100 feet down.

A representative fraction:

• This type of scale representation looks very similar to the representative part (RF).
• However, the representative part avoids the use of units in defining a map scale.
