Statement scale is the type of map scale expression in which scale is expressed in form of a written statement, for example, one centimetre on the map represents ten kilometres on the ground. This can also be expressed in short as 1cm represent 10km or 1cm to 10km.
The following are features of statement scale;
- The scale is expressed as a word statement.
- The scales bear specific units of measurement. The unit of measurement used in the map is smaller than the actual measurements on the ground, for example, 1cm represents 10km
- The word ”represent” should be used. do not use ”equivalent” or ”equal”. For example, do not say one centimeter on the map is equal to ten kilometers on the ground. This is because the statement is not true. instead, say one centimeter on the map represents ten kilometers on the ground.
- The map distance always carries the digit 1 while that of the ground may be less than 1, 1, or more than one.
A statement scale is simple to express. However it may be difficult for users who are not familiar with the unit of measurement used in the scale. If the map is used or enlarged, the scale will not remain the same
