PROCEDURE OF CONSTRUCTING DOT MAPS




A dot map is a statistical map that uses dots of fixed size to represent a fixed number of units in a particular area. They employ a base map of a concerned area and a dot is drawn exactly on the appropriate location on the map. they are useful in representing statistical data like population, plants in the forest, and so on.

The following are procedures used to construct dot maps:




  • Obtain the base map of the area you want to represent and divide it into required sub-regions.
  • Obtain and tabulate the data you want to represent corresponding with sub-regions in the base map.
  • Make a scale and estimate how many items will be represented by one dot.
  • Compute the number of dots to represent total items in each region by using the scale
  • Insert dots in particular sub-regions depending on the total items to be represented as computed earlier
  •  Label and give an appropriate title to your map.
