Explanation: 1 ] -The main aim of maps is to show the location of a place and distribution of variables. Some maps are prepared with special themes. Such maps are called Thematic Maps. Through such maps, distribution of various variables in a region is shown. Distribution of temperature, rainfall, population, etc. is shown on the map according to the data of these variables. These maps are useful to explain the distribution of these variables in the region. Such maps easily bring out the patterns of distribution. To draw distributional maps, we need statistical data of the variables. Distribution can be shown in the three following ways on a map:
- Dot method
- Choropleth method
- Isopleth method
2] - Choropleth method Isopleth method1
1) In choropleth method, the data 1) In isopleth method,the distribution
regarding various geographical was shown with the help of lines
variables is shown by shades or showing equal values.
tints of various colours.
2) While making such maps, the 2) When the distribution of a variable
data used for different variables is continuous , the isopleth method
is obtained through various is then used to show its distribution.
processes such as measurement, For example, altitude, temperature,
surveying etc. rainfall, etc.
3] - The distribution of population of a region can be shown by using dot method.and dot method is best suited to show it.
