Elements of environments are climate, natural vegetation, water, soil, etc. These points differ from one place to another, which create difference in environment.

In a map, different colors are used for denoting these elements.

For example, various elements in climate like rain, temperature, air, humidity etc. are denoted by different numbers and these numbers are decoded at the bottom of the map adhering to global rules of mapping.
