Question

Differentiate:

Isoline map and Dot Density Map.

Answer 1

1. Isoline map:

• Isolines are lines drawn to link different places that share a common value. An Isoline is a line joining equal points.
• Eg: Isobars, Isotherms etc. 

2. Dot Density Map:

• A dot-density map is a type of Thematic map that uses dots on the map to show the values of one or more numeric data fields.
• Each dot on a dot-density map represents some amount of data. In a dot-density map, areas with many dots indicate high concentration of values
