Thematic Maps| Practical Work in Geography Class 12 Notes

Thematic Maps are part of the Practical Work in Geography Class 12. Thermic maps are those maps that denote the density of points on a geographic map by using different colors. The color scales denote the intensity of the hot spots. The pattern of these maps is very clear and they can visualize the different graphic regions by using some variables. These maps are not bounded by any geographic boundaries.

In this article, we are going to discuss the Practical Work in Geography Class 12 with the Thematic Maps in detail.

What is a Thematic Map?

Thematic Maps are individual tropic maps that focus on specific themes including rainfall, heat, precipitation, vegetation, population density, roads, and political boundaries. These maps make the spatial patterns more clear and give us an individual overview of these aspects of a specific location.

Here are the major specifications of the Thermic Maps as mentioned below.

• The Thematic Maps are very useful to analyze the raw information of a specific location.
• These maps give an overview of the geographic pattern and different trends based on the raw data sets.
• These maps are really useful for the fights as they can provide small redundancies between the consecutive images.

Let us discuss the different types of thermic maps as mentioned below.

Choropleth Thematic Map

Choropleth Thematic Map represents the data values of some specific locations with various colors and patterns. In this, the data can be plotted as the classes and each class carries a specific color.

These maps are generally used to –

• Measure the population density.
• Depict the total population of a location
• Represent the demographics and sales data

Bivariate Thematic Map

A Bivariate Thematic Map is generally used to represent two sets of data on the same map with different colors. These types of thermic maps are really complex and sometimes difficult to read.

These maps are generally used to show and analyze –

• Contrast Data Set
• Competitor Analysis
• A Year’s Performances

Dot Density Thematic Map

Dot Density thermic maps represent the data with dots. These maps are the better way to represent density. The dots are really helpful to identify the data in a high-density data set. These thermic maps majorly used to –

• Represent a large amount of data
• Analyze the spatial pattern with density

Isopleth Thematic Map

Isopleth thermic maps are used to represent the data with some colors and shades. These maps are similar to the choropleth maps. These maps are majorly used to represent those data that are not grouped yet. These maps are beneficial for depicting –

• Weather and Climate Patterns
• Data for Large and Huge Regions
• Changes over time and Distances

Heat Thematic Map

Heat Thematic Maps are generally used to measure the density by using different colors. The dark shades are mainly used to represent the higher density and white color is used to show the lower density areas. These types of maps are generally used for –

• Sales and Marketing analysis
• Measuring the Density
• Locate the Unreserved Regions

FAQs on Practical Work in Geography Class 12 Notes Thematic Maps

What is a thematic analysis map?

You can use thematic (map) analysis to analyze qualitative data from user studies, such as interviews, focus groups, workshops, diary studies, or contextual inquiries. It is possible to analyze data with behavioural elements or attitudes (thoughts, believes, and reported needs etc.)

What is the difference between a concept map and a thematic map?

A concept map is a type of map which represents suggested relationships between concepts and thematic web chart is a chart is a type of map which represents a particular theme connected with specific geographic area.

What is thematic map types?

Types of Thematic Maps. There are several different types of thematic maps. These types include isoline maps, cartogram maps, choropleth maps, graduated symbol maps, heat maps, dot-density maps, and flow-line definition maps.

Why is a thematic map?

A thematic map is also called a special-purpose, single-topic, or statistical map. A thematic map focuses on the spatial variability of a specific distribution or theme (such as population density or average annual income), whereas a reference map focuses on the location and names of features.

What is a thematic map example?

These are maps which depict information on a particular topic or theme. The detail portrayed on a thematic map may be physical, statistical, measured, or interpreted, and sometimes requires specialist knowledge by the map user. Weather, population density and geology maps are examples of thematic maps.

What is thematic web?

A thematic web chart is a specially made for the showing a geographical area as weather distribution and population density. It focuses in special themes of subjects and used to provide information about that location.
